GENERAL 1.01 This section describes ADC’s E1 Digital Signal Cross-Connect (DSX) System, which serves as centralized termination, test access, cross-connect points and distribution frames for digital equipment. DSX System components are available that work with the E1 bit rate and signal level of 2.048 Mbps. 1.02 Signals from all digital equipment are maintained at an equal level at the DSX by a number of methods which compensate for the various cable lengths. This allows for testing, patching, and rearranging of equipment at the DSX without having to readjust signal levels. 1.03 ADC’s DSX Systems are suitable for both large and small offices, and customer premises. Each can be designed and configured by the user or by ADC to meet the specific requirements of the office in which it is to be located. Systems are modular and can be designed to handle all cross-connect requirements in an office, or to supplement existing office crossconnect systems. DSX Systems can be expanded later by simply adding more DSX assemblies. 2. FUNCTIONAL DESCRIPTION 2.01 A DSX System consists of any number of individual DSX terminations to which network elements are connected and cross connected. Each digital E1 circuit requires two DSX terminations as shown in Figure 1-1. Each DSX termination consists of access points and two cross-connect terminals. The circuit is completed by cross connecting the IN and OUT circuits, either by jumpers at the cross-connect terminals or patch cords to the jacks. Page 1-1 © 1996, ADC Telecommunications, Inc.

Digital DSX Circuit 2.02 Typical DSX circuits for E1 systems are shown in Figure 1-2. Cables from the equipment inputs and outputs are connected to the DSX equipment IN/OUT terminals. By means of cable connected between DSX cross-connect terminals, any equipment input or output may be connected to any other equipment input or output.

Typical DSX Circuits Page 1-2 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 In Figure 1-2, network elements A, B, and C are connected to the DSX equipment 2.03 IN/OUT terminals of three different DSX jacks. Network elements A and C are then connected together at the DSX by patch cords on the cross-connect terminals. The corresponding tracer lamp terminals (TL) are also jumpered together. Cross-connected elements A and C can now be identified, monitored and tested as follows: • Circuit Identification – Insertion of a functional or dummy plug into either of the two DSX MON jacks causes the tracer lamps at each end of the corresponding cross-connect jumper to flash for about thirty seconds and then remain lit. This gives a visual indication of the equipment units that are jumpered together. • Bridged Testing – Test equipment patched into either of the MON jacks allows testing without interrupting the signals between the A and C equipment. • Split-circuit Testing – Test equipment patched into an IN or OUT jack splits the A-to-C equipment circuit for direct testing of either equipment unit. In addition, patch cords can be used to split cross-connected network elements, and 2.04 connect either of the two elements to a third element. In Figure 1-2, network element C is temporarily patched to network element B. As shown in Figure 1-2, numerous testing and patch-around configurations are possible, 2.05 all of which are established permanently or temporarily at the centrally located DSX System. As a result, many benefits can be immediately realized in the following areas: Note: The Operation section of this Manual provides schematic diagrams and step-bystep procedures for most of the functions performed at the DSX. A. Testing and Fault Isolation By terminating all digital operational and test equipment at one central point (the DSX), 2.06 overall office equipment preventive and corrective maintenance can be performed at that central location. Identification of existing or developing problems is readily accomplished at the DSX by: • Bridged or intrusive testing at DSX jacks connected directly to network element inputs and outputs. • Patching in spare equipment for suspected faulty units. B. Interoffice Service Restoration The loss of a major facility between two locations may isolate or greatly reduce the 2.07 service capability between the two sites. To temporarily restore partial communications between these two sites, several circuits can be rerouted through a third site by simple patch arrangements at the DSX Systems at the three sites. After the facility is repaired, these temporary patches are easily removed and normal service between the two sites is restored. Page 1-3 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 C. Exchange Layout The DSX makes it possible to add equipment to an exchange without major changes in 2.09 the exchange layout. Equipment is simply installed where space is available and then wired to the DSX. Cross-connect jumpers on the DSX connect the equipment into the desired exchange configuration. D. Digital Switch Cutover The DSX simplifies the cutover of a new digital switch. When a digital switch is 2.10 installed, it is terminated on the DSX. The existing cross connections serving the analog switch are then replaced by temporary patch cords and new cross-connect jumpers are installed for the digital switch. Cutover to the new switch is then completed by removing the temporary patch cords. E. Exchange Record Keeping The DSX minimizes record keeping by providing large designation strips and cards for 2.11 labeling of connected equipment locations and other terminations. In addition, color-coded tracer lamps are available to readily identify different types of equipment cross connected at the DSX. 3. SYSTEM COMPONENTS All DSX circuits are available in various bay configurations, which include both 3.01 prewired and stand-alone modules. The DSX bays may also be provided with various types of test equipment and signal sources, and are equipped with the necessary panels and hardware for connecting and routing cables and wires between bays and bay lineups. The following paragraphs briefly describe the bays, modules, and panels available for 3.02 designing a DSX System. System components are described in detail in ADC’s DSX Product Catalogs. A. High-Density Bays Three types of high-density, DSX bays are available. All high-density bays are 3.03 preassembled and prewired, and may be ordered custom-built to meet specific exchange needs. These bays do not require spacers between bays for cable management. Standard High-Density Bays Standard high-density bays are of various sizes and circuit capacity, with a 2.13 m (7.0 3.04 ft) bay containing as many as 832 DSX circuits.

Typical DSX Super High-Density Maintenance Bay B. Skeleton Bays The Skeleton Bay is designed to ease the expansion of the DSX by providing all cable 3.10 management before it is needed. Without the Skeleton Bay concept, as installed DSX line-ups are expanded, DSX panels. Jumpers are often restricted from running in any direction since jumper rings did not exist at unequipped panel positions. When jumpers are pulled too tight across unequipped positions, feeding them into new rings is difficult, if not impossible. Jumpers often cut across corners as they transition from vertical to horizontal wireways. Page 1-8 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 The Skeleton Bay concept allows existing jumpers to remain undisturbed when adding 3.11 panels to the DSX, and jumper routing is not restricted in any direction since all wireways are already established. Skeleton Bays are the recommended rack and cable distribution system for use with DSX lineups. Figure 1-7 shows the components that are included with the Skeleton Bay.

Skeleton Bay Components C. Drop-In Bays Drop-in Bays are also preassembled and prewired; however, they are comprised of any 3.12 of the various DSX modules and panels described in the following paragraphs. Input/output and cross-connect terminals and corresponding patching jacks and indicators all reside on each DSX assembly rather than in individually segregated fields across the bay. These bays may be shipped with any number of DSX modules or panels installed, and as termination requirements increase, additional modules can be “dropped in” in the office and wired into the existing bay. A 2.13 m (7.0 ft) drop-in bay provides for termination of up to 924 circuits. D. DSX Modules and Panels Bantam jack DSX modules are available in various sizes and configurations and may 3.13 contain up to 90 individual DSX positions to which digital equipment may be terminated and cross connected. The front and rear views of a typical 64-circuit module are shown in Figures 1-8 and 1-9. Page 1-9 © 1996, ADC Telecommunications, Inc.

DSX-Best-64 Module (Rear View) A combination 120Ω/75Ω panel is available for terminating a mixture of E1 120Ω and 3.14 75Ω cables. Use of this panel should be limited to small office applications since large office jumper management systems generally cannot support a mixture of coaxial and twisted-pair cross-connects. It is recommended that no more than two bays of combination panels be used; therefore future office growth should be seriously considered prior to installation. Interbay Patching Modules Interbay patching modules are jackfields used for patching between bays and lineups 3.15 when patch cord lengths become prohibitive. These modules allow use of a series of short patch cords to connect any DSX terminations in the same or other DSX lineups. The point of signal origin on a bay is patched to the closest interbay module and from there the signal is transmitted via hardwired connections to other interbay modules in the bay lineup(s). The point of signal destination is then patched to its closest interbay module to complete the circuit. Interbay patching modules are available with Bantam jacks as shown in Figure 1-10. 3.16 This panel is equipped with busy indicators to show which jack circuits are in use at any time.

Bantam Interbay Module Cross-Aisle Panels Cross-Aisle Panels are comprised of double-sided wire-wrap terminals, with one side 3.17 used to terminate tie cables to another lineup and the other side used to terminate cross-connect wires. Cross-connects between lineups are completed by connecting short jumpers at each end of the tie cables to the selected DSX circuits. This eliminates the need to place long overhead jumpers. Cross-Aisle Panels are available in several configurations and circuit quantities, one of which is shown in Figure 1-11. 1 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 TL T R T1 IN R1 90 95 100 TL T OUT R T1 IN R1 OUT 8593-A Figure 1-11.

Typical Miscellaneous Jackfield Repeaters 3.20 Various models of repeaters are available for regenerating low level digital signals. These repeaters are contained on circuit cards and plug into a variety of chassis and panels. Dual Intraoffice Repeater The Dual Intraoffice Repeater regenerates any standard E1 (2.048 Mbps) signal. Each 3.21 repeater consists of a pair of signal regenerators on a single printed circuit board. Depending on the mode of operation required, the two regenerators may be configured to operate in the same direction or in opposite directions. An artificial line at the repeater input provides shaped line loss for an input signal level 3.22 of 0 to -27 dB relative to the Digital Distribution Frame signal level. The repeater output provides the standard E1 signal level up to a distance of 165 m. (543 ft.). Selectable equalization networks correct for the following distances over 120-ohm twisted-pair cable: • 0 to 67 meters (0-to 220 ft.) • 67 to 134 meters (220 to 440 feet) • 134 to 200 meters (440 to 655 ft.) Page 1-12 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 Typically located between DSX bays where cross-connects exceed the 18 meters (59 ft.) 3.23 limit or when network element cabling exceeds the 165 meters (543 ft.) limit. >165 M NETWORK ELEMENT DSX 0 - 165 M INTRAOFFICE REPEATER 0 - 165 M >18 M DSX DSX 0 - 165 M INTRAOFFICE REPEATER 0 - 165 M 8669-B Figure 1-13. Dual Intraoffice Repeater Schematic Dual Bridging Repeater The Dual Bridging Repeater shown in Figure 1-14 has two regenerators that, depending 3.24 upon the mode of operation, are configured to operate in the same direction or in opposite directions. Each repeater output will provide the standard E1 level signal up to 45.72 m (150 ft.). This repeater automatically compensates for a flat loss input signal level of -14 to -26 dB, relating to the DSX/DDF level. Typically this type of repeater is used to temporarily reroute service without service interruption. Page 1-13 © 1996, ADC Telecommunications, Inc.

PIX-DSX Bays The PIX-DSX Bay, shown in Figure 1-22, is modular for easy expansion at the user's 3.32 site. Each 2.13 m (7.0 ft) bay may contain up to 832 DSX circuits (13 DSX mounting shelves by 64 circuits each). The modular design allows for installation of a minimal system configuration to meet the immediate needs of a site, and then expanding it as necessary® by adding individual PIX-DSX circuit cards. Up to eight circuit cards are plugged into octapak housings that fit into a mounting shelf. 8490-A Figure 1-22. PIX-DSX Bay Page 1-18 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 PIX-DSX Shelf The PIX-DSX Shelf, shown in Figure 1-23, provides the mounting for up to eight 3.33 octapak housings across the width of the bay. Shelves are available in heights of 11.43 and 12.7 cm, widths of 48.26 or 58.4 cm (19 and 23 inches) and depths of 30.48 or 38.1 cm. Brackets and rings across the front bottom of each shelf provide for management of cross-connect wiring to the vertical wire rings at the sides of the bay. They are also available for either waterfall or standard equipment cabling arrangements. The 12.7 cm high shelves provide better management of cross-connect wiring, while the 38.1 cm deep shelves provide better management of network element cabling. 6900-A Figure 1-23. PIX-DSX Shelf All network element (NE) cabling to the PIX-DSX Bay is terminated on the rear of 3.34 octapak housings. This allows for cabling of an entire PIX-DSX Bay and then purchase and install individual circuit cards as they are required for service. All NE E1 cable leads and crossconnect terminals are accessible from the front of the bay for full front installation, operation, and maintenance. This allows PIX/DSX bays to be located back-to-back or against a wall.

PIX-E1 Loop-back Interface Card (LBIC) Each PIX-E1 Loopback Interface Card (LBIC) provides a high density, loopback/E1 3.42 termination. The LBIC also provides remote loopback capability for routine maintenance and troubleshooting. The LBIC operates at the standard E1 (2.048 Mbps) signal and is transparent to line 3.43 code, framing format, and Bipolar Violations (BPVs). The LBIC terminates the Network OUT E1 line and regenerates the received signal to the Customer IN side. It has input sensitivity down to 27 dB below a nominal E1 level (3 V peak). The LBIC recognizes In-Band Loopback codes in -2 an environment with a bit error rate of up to 10 . Additional factory set In-Band Loopback codes are also available. Figure 1-29 shows a typical PIX-E1 LBIC connection. Note: In-band testing is intrusive. Page 1-22 © 1996, ADC Telecommunications, Inc.

Typical PIX-E1 LBIC Connection When the LBIC loses its +5 V power, E1 signal from the Network OUT to Customer IN 3.44 experiences a momentary hit but recovers when the transmission path is switched to an on-board un-regenerated signal path. The signal from Customer OUT to Network IN is not affected. When power is restored or applied to the LBIC, the LBIC will default to normal mode operation, regenerating the Network OUT signal to Customer IN. PIX-E1 Cross-Aisle Repeater Circuit Cards Each PIX-E1 cross-aisle repeater circuit card incorporates standard ADC Bantam jacks 3.45 with a E1 regenerator. The regenerator is located in the E1 circuit transmission path just before the OUT jack as shown in the connection diagram in Figure 1-30. These repeaters are used to regenerate the E1 signal at a DSX when the cross-connect distance exceeds 18 m (59 ft). Page 1-23 © 1996, ADC Telecommunications, Inc.

In addition, complete installation instructions are provided in separate installation guides specific to a particular chassis, panel, or module. Refer to the Related Manuals listing in the front of this manual for the ADCP number corresponding to a specific installation manual. 2. EXCHANGE REQUIREMENTS 2.01 Details of conditions required to install the DSX System in a central exchange are described in the Global DSX (E1) Planning and Engineering Manual, ADCP-80-351. A proper installation can not be accomplished unless the site has been appropriately prepared in accordance with the guidelines provided in the Planning and Engineering Manual. Additional installation-related specifications are provided below. A. Space and Floor Loading 2.02 The DSX System consists of various modules and panels mounted in one or more 48.26 cm (19 in) or 58.42 cm (23 in) equipment racks. The height of the racks may be 2.13 m (7 ft), 2.74 m (9 ft), or 3.5 m (11.5 ft). Approximate dimensions of the specific system purchased may be ascertained by examination of the system design as shown in ADC’s DSX Product Catalogs. A fully configured uncrated DSX bay may weigh up to 239 kg. (525 lb). Page 2-1 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 B. Environment Operational The DSX System will operate in any ambient temperature and humidity within the 2.03 following ranges: • Temperature: 0° C (+32° F) to +50° C (+122° F). • Humidity: 5% to 95% relative humidity without condensation. Shipping and Storage The DSX System can be shipped and stored in any ambient temperature and humidity 2.04 within the following ranges: • Temperature: –40° C (–40° F) to +70° C (+168° F). • Humidity: 5% to 95% relative humidity without condensation. 3. UNPACKING AND INSPECTION Caution: A crated DSX bay may weigh as much as 318 kg. (700 pounds), depending on its size and configuration. An adequately rated and secured block and tackle or overhead hoist must be used while uncrating, positioning and securing each bay. 3.01 Remove all items from their shipping containers. Each chassis, module and panel includes a separate package of parts. Verify that all parts on the packing slip have been received, before shipping containers are discarded. If there are any damaged or missing parts, file a claim with the commercial carrier and notify ADC as defined in Section 5 - General Information. 4. HARDWARE INSTALLATION A. Bay Positioning and Mounting 4.01 Set each DSX bay in its assigned position according to the predefined layout. Secure each bay to the floor and to adjacent bays or frames, using spacers between bays where specified by system design. If overhead support is required, secure the bays to the overhead supports using appropriate hardware. Refer to the Unequal Flange and Network Rack Installation Guide, ADCP80-345, for detailed installation instructions. Page 2-2 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 B. Chassis, Module and Panel Positioning and Mounting The unmounted package of parts contains mounting brackets, cable rings, designation 4.02 strips, installation drawing, etc. Place mounting brackets on the chassis, modules or panels and install them in their assigned bay positions using 12-24 × 0.95 cm (0.375 in) mounting screws. The remaining parts should then be placed as shown on the installation drawing. Note: The 12-24 × 0.95 cm (0.375 in) mounting screws must be ordered separately. Longer screws should not be used since they could damage cables on unequal flange type racks. ETSI/IEC Cabinet Installation If you are installing an ADC DSX chassis into an existing ETSI-compatible cabinet, the 4.03 DSX chassis mounting brackets must be replaced with adapters to conform to the mounting hole spacing of the ETSI cabinet. Refer to the Planning and Engineering Manual, ADCP-80-351, for detailed adapter bracket specifications and ordering information. 5. SYSTEM WIRING AND CABLING Wiring and cabling the DSX System into the office requires connection of office power 5.01 and ground, wiring of cross-aisle and interbay patching panels, cabling of network element input/output circuits, and installation of all cross-connect jumpers. The following paragraphs give procedures for installing all wiring and cabling, although all high-density bays and some drop-in (module) bays are shipped with intrabay wiring already installed. Caution: The system power input must be off or disconnected at the office distribution panel, before connecting any DSX wiring or cabling. A. Power Wiring The DSX System operates on -48 Vdc filtered power, fused or breakered at the power 5.02 distribution panel. Approximate current requirements can be calculated based on a single flashing Bantam LED draws .010 Amps. The number of LEDs lit at any one time will depend on local patching and testing 5.03 procedures. It is recommended that individual DSX modules or panels be fused at the fuse panel with a 0.5 Amp. fuse and connected to the fuse panel using 0.511 mm (24 AWG) solid copper wire. Each high-density bay or fuse panel dedicated to an individual DSX bay serving only tracer lamps and LEDs should be connected with 0.813 mm (20 AWG) solid copper wires to the power supply and fused with a 3.0 Amp. fuse. Page 2-3 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 B. High-Density Bays Standard and waterfall high-density bays normally have battery and ground terminal 5.04 strips or blocks as shown in Figures 2-1 and 2-2. These terminals are located at the rear of the bay to provide connection to the power and ground. Connect power and ground to the HighDensity DSX bays as follows. 1. Connect –48 power to the –48 V terminals on the terminal strip/block. 2. Connect –48 Vdc power ground to the B GND terminals on the terminal strip. 3. Connect office frame ground to the C GND terminal. This is the recommended chassis grounding procedure. Note: The metal strap between the C GND (chassis ground) and S GND (shield ground) terminals may be removed to isolate shield ground from chassis ground. 1 2 3 4 5 6 7 8 9 10111213 C GND B GND S GND 1 2 3 4 5 6 7 8 9 10111213 –48 V 8441-A Figure 2-1.

Typical Information Shown on DSX Installation Drawings At the back of the module are terminal blocks designated TB #1 through TB #15. The 5.14 top row of terminal blocks (TB #1 through TB #7) is used for the cross-connect jumpers, while the bottom row (TB #8 through TB #15) is used for terminating the network elements. Page 2-8 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 TB #1 through TB #3 and part of TB #4 are used to cross-connect the B CKTS, and the 5.15 remaining part of TB #4 along with TB #5, TB#6 and TB #7 are used to cross-connect the A CKTS. The upper two rows of pins on these terminal blocks are internally wired to the output jacks, and the lower two rows are internally wired to the input jacks. TB #8 through TB #10 and part of TB #11 are used to terminate network element inputs 5.16 and the remaining part of TB #11 along with TB #10 through TB #15 are used to terminate network element outputs. The upper two rows of pins on these terminal blocks are internally wired to the corresponding A jacks, and the lower two rows are internally wired to the corresponding B jacks. The connection table in Figure 2-7 shows the same terminal block information in tabular 5.17 form. The table shows circuits 1 and 32 of the A CKTS and circuits 1 and 32 of the B CKTS. Information on the remaining circuits can be interpolated from the table. The left half of the table shows cross-connect terminal block information (TB #1 through TB #7) and the right half of the table shows network element input/output terminal blocks (TB #8 through TB #15). For each circuit, the table identifies the terminal block (TB), vertical row of pins and individual pins. F. Cable Routing DSX Systems are wired to the office equipment by means of cables at the back of each 5.18 bay. All cabling should be in accordance with the rules defined in the DSX System Design section of the Global DSX (E1) Planning and Engineering Manual, ADCP-80-351. If the cables are routed to the bay from above, cable attachment should start with the 5.19 lowest panels/modules and work up as shown in Figure 2-8. If the cables are coming from below, cable attachment should begin at the top as shown in Figure 2-9. Page 2-9 © 1996, ADC Telecommunications, Inc.

Cable Routing from Bottom to Top All cables should be secured to brackets at the back of the bay (waterfall bays) or within 5.20 the duct (non-waterfall bays). The cable jacket should be stripped from an area past the last tie on the cable bracket at a level about even with the wire-wrap pins to which the wires will be connected. A six-inch service loop should be left before the cable is routed to the wire-wrap terminals. Network Elements Cabling Using cables and wire-wrap tools, connect the network elements to their designated DSX 5.21 input/output circuits, maintenance panels and modules. Typical connections are defined in the installation drawings accompanying the DSX equipment. Refer to Figure 2-7. Terminate cabling for each network element input circuit to one pair of IN wire-wrap 5.22 terminals, and each output circuit to one pair of OUT wire-wrap terminals. Cross-Aisle Panel Cabling Cross-aisle tie cables between lineups in E1 systems should be interconnected in a 5.23 manner similar to Figure 2-10 or 2-11. Connect the tie cables to the terminals on the rear of the cross-aisle panels as defined in the accompanying installation drawing. The OUT terminals of the originating cross-aisle panel connect to the IN terminals of the terminating cross-aisle panel, and the IN terminals of the originating cross-aisle panel connect to the OUT terminals of the terminating cross-aisle panel.

Cross-Connect Wiring Cross-connect jumpers should be routed as shown in Figures 2-16 and 2-17. Whenever a 5.26 cross connect changes direction, it should do so at a point where a ring, tray or fanning strip is placed. This will allow the cross connect to be dressed neatly with no strain and without interfering with any other portion of the bays. All cross-connect jumpers should use the horizontal wireways between bays, and the vertical wireways within the bay. To prevent unnecessary jumper buildup and congestion, all discontinued cross connects should be removed from the DSX wireways.

Recommended Cross-Connect Wiring in Super High Density Bays All cross-connects should be routed on the same horizontal wireway as the originating 5.27 point and then vertically in the wireway nearest the termination point. The cross-connects should be threaded behind the horizontal wireways in all vertical ducts with approximately 12.7- to 17.8 cm (5- to 7-in) of slack. The slack should remain in the horizontal wireways when entering and leaving the vertical duct. The DSX drop-in modules with cross connects in place holds wire congestion to a 5.28 minimum if all recommendations are carefully followed. This not only simplifies installation, but also provides for quick wire traceability and easy DSX expansion and maintenance. Page 2-15 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 DSX Cross Connects Using five-conductor 0.511 mm (24 AWG) jumpers, cross-connect DSX circuits as 5.29 shown in Figure 2-17. Terminal identification is as shown in the installation drawing accompanying each module/panel (see Figure 2-8). • Connect the TL of the first termination to the TL of the second termination (green wire). • Connect the OUT of the first termination to the IN of the second termination (blue wire and blue and white wire). • Connect the IN of the first termination to the OUT of the second termination (orange wire and orange and white wire). Remove any discontinued jumper by disconnecting each end and cutting off the bare 5.30 ends. Remove each end of the jumper from the vertical wireways, and carefully remove the jumper from the horizontal wireway by pulling at either end. This method will allow the jumper to be removed without snagging or placing undue strain on the remaining jumpers. Page 2-16 © 1996, ADC Telecommunications, Inc.

ADCP-80-352 1st Edition, Issue 1, October 1996 PROCEDURE 3 DIGITAL OFFICE EQUIPMENT TEST This procedure is used to test two network elements wired together at the DSX System. The units can be tested either with or without interruption of the circuit cross-connect. Note: Many of the office test equipment units and signal sources are accessible at the DSX Miscellaneous Jackfield. These can be patched directly from the Miscellaneous Jackfield to the DSX jacks. STEP PROCEDURE 1 To test a circuit at the cross-connect point of the two network elements without interrupting the cross-connect circuit, plug the appropriate test unit into the desired monitor jack and perform the tests. Note: When a plug is inserted into the monitor jack, the tracer lamps of the corresponding cross-connected circuits will flash for about 30 seconds and then remain lit. 2 To open a cross-connect circuit and test a network element whose output is wired to the DSX, plug the appropriate test unit into the OUT jack of the circuit to be tested. 3 To open a cross-connect circuit and test a network element whose input is wired to the DSX, plug the appropriate test unit into the IN jack of the circuit to be tested.

ADCP-80-352 1st Edition, Issue 1, October 1996 PROCEDURE 8 INTERBAY PATCHING BY MEANS OF SHORT PATCH CORDS This procedure is used to patch between bay lineups or between distant bays in the same lineup, without the use of long patch cords. Patching is accomplished with several short patch cords, using the multipled, hardwired Interbay Patching Panels. A typical example is when a DSX circuit in bay 2 is patched to a DSX circuit in bay 18 of the same lineup using Interbay (IB) Patching circuit 3. STEP PROCEDURE 1 Install patch cord between DSX OUT jack in bay 2 to IB IN jack 3R on bay 4. (Busy LEDs on jack 3 of IB panels in bays 8, 12,16 and 20 will light). 2 Install patch cord between IB OUT jack 3L on bay 16 to DSX IN jack in bay 18. (Busy LEDs on jack 3 of IB panels in bays 8 and 12 will remain lit, LEDs on jack 3 of IB panels in bays 16 and 20 will be extinguished). 3 Install patch cord between DSX OUT jack in bay 18 to IB IN jack 3L on bay 16. 4 Install patch cord between IB OUT jack 3R on bay 4 to DSX IN jack on bay 2. Note: Busy LEDs on jack 3 of IB panels on bays 8 and 12 will remain lit until patches are removed. IB jack circuit 3 between bays 16 and 20 may be used for another patch.

Troubleshooting Troubleshooting of the DSX System consists of visual inspection and continuity testing. 3.03 Cross-connections can be quickly checked by bridging them with patch cords to the corresponding IN and OUT jacks. Refer to the Maintenance section of ADCP-80-311 for specific fault isolation processes for the PIX-E1 Repeater Shelf. B. Tracer Lamp Replacement Burned out tracer lamps are replaced at the front of the DSX bay. Lamps are removed by 3.04 pulling them from the panel sockets. No special tools are required. Replacement lamps must be inserted with the negative (–) terminal up. C. Fuse Replacement Burned out fuses are replaced at the front of the fuse panel. Fuses are removed by pulling 3.05 them from the panel sockets and installed by pressing them into the panel sockets. No special tools are required. Caution: A replacement fuse must have exactly the same current rating as the fuse being replaced. D. Jack Replacement 3.06 Bantam jacks can be replaced at the front of the bay. Use of ADC’s jack repair kit is recommended to support the jack panel during jack replacement. The jack repair kit consists of two panel supporting brackets, five DSX jacks, a Phillips screwdriver, and the necessary mounting screws. If this kit is not used, or if the jack panel is not mounted by screws at the front of the bay, another means of panel support must be provided. Proceed as follows to replace a DSX jack. Caution: The –48 Vdc power must be turned off or disconnected from the bay/panel during jack replacement. 1. The support brackets included with the jack repair kit include two sets each of three pieces identified in Figure 4-1. Depending on how the front panel assembly attaches to the DSX module either brackets A & B will be used or A & C will be used. If the mounting screws holding the front panel are attached from the front, use brackets A & B. If the mounting screws holding the front panel attach from the side, brackets A & C should be used. See Figure 4-2. Page 4-2 © 1996, ADC Telecommunications, Inc. ADCP-80-352 1st Edition, Issue 1, October 1996 5.35 CM 3.53 CM BRACKET #A 6/32 (2) BRACKET #B BRACKET #C LEFT RIGHT 8482-A Figure 4-1.
