Class 1 Laser product, Luokan 1 Laserlaite, Laser Klasse 1, Appareil A'Laser de Classe 1 4008217 Rev B Prisma T1/E1/J1 Media Converter Module Installation Instructions 7 Product Description Prisma T1/E1/J1 Module Each Prisma T1/E1/J1, TP/FX module includes one RJ-48 and one pair of ST or SC fiber optic connectors (or one small form factor duplex connector) and requires one slot in any SNMP-manageable Prisma MediaCenter™ chassis or an unmanaged MediaCPE™ chassis. Also available for single-strand fiber, the Prisma T1/E1/J1, TP/SSFX module includes one RJ-48 and one SC fiber optic connector. Prisma T1/E1/J1, TP/SSFX modules allow two wavelengths to share one fiber strand — Full-Duplex data travels on different wavelengths (1310 nm and 1550 nm) — doubling the capacity of installed fiber. Note: In order to function correctly, you must have a Prisma T1/E1/J1 module at BOTH ends of the conversion. The data transmitted on the fiber ports can only be received and interpreted by the receive fiber of another Prisma T1/E1/J1 module. Prisma T1/E1/J1 Module Illustration Refer to the following illustration for a view of the module front panel. 8 Prisma T1/E1/J1 Media Converter Module Installation Instructions 4008217 Rev B Configuration Instructions Introduction The Prisma T1/E1/J1 module can be configured for various features (see DIP Switch Settings later in this document) that help improve the performance and reliability for your T1/E1/J1 requirements. The following instructions are for both managed and unmanaged modules. Managed Modules To manage Prisma T1/E1/J1 modules, an SNMP agent must be present i.e., the MediaCenter chassis with embedded management. When using Prisma T1/E1/J1 modules in a managed environment, manually configure the features that you cannot configure via management software prior to installation of the module. (See Choosing Your Settings and DIP Switch Settings later in this document for configuration instructions/description of the functions). After completing necessary pre-installation settings, install the Prisma T1/E1/J1 module (see Module Installation Instructions later in this document), and configure additional features via the software. The features that are configurable via management software include: Loop Back Selection, Transmit Data Source, Line Encoding, NRZ (Non-Return-to-Zero), and Receive Equalizer Gain Limit (EGL). Within the PrismaView™ software for media conversion, these settings are configured in the Module Detail section of the main viewing screen, under the picture of the module. Refer to the help file for more information. When installed in a MediaCenter chassis, Prisma T1/E1/J1 modules are only SNMPmanageable and software configurable is connected to a Prisma T1/E1/J1 module installed in a managed chassis. Some features may not be software configurable on a remote unit. Note: Management software overrides any hardware settings (e.g., jumper, switch, etc.), so you MUST configure a module that will be managed via the software. Until a module installed in a managed chassis is configured via the software, the module (and its LEDs) may not work properly. Important: When testing, it is recommended that you test your modules first in an unmanaged environment. To do this, turn the SNMP management switch to OFF on a MediaCenter chassis, or remove the management module from a MediaCenter chassis. Follow the unmanaged configuration instructions, then install the module, connect the cables, and test the LEDs. When finished, reactivate management and configure the unit via the software. Continued on next page 4008217 Rev B Prisma T1/E1/J1 Media Converter Module Installation Instructions 9 Configuration Instructions, Continued Unmanaged Modules Before installing, an unmanaged Prisma T1/E1/J1 module can be configured for its selectable features via DIP switches located at position S3 and S2 and jumpers located at positions JP1 and JP2 in the PCB.

Knowledge of the distance to the main office and the troubleshooting capabilities desired must be known in order for installation to be successful. T1/E1/J1 Selection This feature selects the data rate that the module will be converting from either T1, E1, or J1. The default is OFF, with T1 mode selected. Receive Equalizer Gain Limit This option allows the user to compensate for diminishing signal intensity over the data line by adjusting the sensitivity of the UTP receiver. By setting the Receive Equalizer Gain Limit (EGL) correctly, the reliability of the signal is ensured. Line Encoding This option allows the user to set the transmit/receive encoding for HDB3, B8Z3, or AMI. Transmit LIU Waveshape (Line Buildout) This option controls the waveshape being output by the transmitter. This helps to correct problems related to cabling (i.e., cross-talk, electromagnetic interference, etc.). Improperly setting this switch causes signal degradation. Receive LIU Termination (Line Termination) This option sets receive termination. This is used to properly terminate cables that prevent signal reflections that can cause signal degradation. Transmit Data Source This is a diagnostic tool that sends specific patterns of data to determine problems along the cable. The user can set the module to send either a PRBS (pseudorandom bit sequence), an alternating ones and zeros (TAOZ), or an unframed all ones (TUA1) code, depending on your diagnostic needs. The default is with both switches in the ON position (standard data). Jitter Attenuator Select The user selects Jitter Attenuation on the UTP transmit or receive side. This decreases jitter in the data stream that increases data reliability. The jitter attenuator is always enabled. Continued on next page 14 Prisma T1/E1/J1 Media Converter Module Installation Instructions 4008217 Rev B Choosing Your Settings, Continued Remote Management This mode allows for the configuration of a remote unit, facilitating easy testing of the line integrity of the remote unit’s copper port. As Prisma T1/E1/J1 modules are always deployed in pairs, if remote management is desired, the Remote Management feature must be enabled on the REMOTE unit only. When Remote Management is enabled, the local unit can configure all SNMP-configurable features for both units. Refer to the Module LED Indicators later in this document for functionality. Note: When the Remote Management feature is enabled on the remote unit, the remote unit’s chassis must have SNMP-management disabled (i.e., the SNMP switch turned OFF on the MediaCenter chassis). Loopback Selection This is another diagnostic tool that enables the user to test the integrity of the line by allowing the data to be looped back. Loopback test modes include: Fiber Analog Loopback, Fiber Digital Loopback and Twisted Pair Digital Loopback. Monitor/Boost Mode This mode boosts the UTP receive signal (i.e., internal linear gain boost). This helps the UTP receiver to compensate for line loss. NRZ (Non-Return-to-Zero) A method for transmitting and recording data so that it keeps the sending and receiving clocks synchronized. This is especially helpful in situations where bit stuffing is employed— the practice of adding bits to a data stream so it conforms with communications protocols. 4008217 Rev B Prisma T1/E1/J1 Media Converter Module Installation Instructions 15 Crossover/Pass-Through Connection Introduction The Prisma T1/E1/J1 module comes with an RJ-48 UTP connector that features a push-button switch, located next to the port, for selecting a crossover workstation or pass-through repeater/hub connection. To select a cross-over connection, press the push-button IN. A pass-through connection is selected when the push-button is OUT. If unsure what type of connection is needed, set the push-button switch to the position that DOES NOT make the NO LNK LED glow. 16 Prisma T1/E1/J1 Media Converter Module Installation Instructions 4008217 Rev B Module Installation Instructions Electrostatic Discharge Precautions Electrostatic discharge (ESD) can cause damage to the plug-in Media Converter modules that install into the chassis. Always observe the following precautions when installing or handling an add-in module or any board assembly. 1. Do not remove the module from its protective packaging until you are ready to install it. 2. Wear an ESD wrist grounding strap before handling any module or component. If you do not have a wrist strap, maintain grounded contact with the system unit throughout any procedure requiring ESD protection. WARNING: Integrated circuits and fiber optic components are extremely susceptible to electrostatic discharge damage. Do not handle these components directly unless you are a qualified service technician and use tools and techniques that conform to accepted industry practices. 3. Hold boards by the edges only; do not touch the electronic components or gold connectors. 4. After removal, always place the boards on a grounded, static free surface, ESD pad, or in a proper ESD bag. Do not slide the board over any surface. Continued on next page 4008217 Rev B Prisma T1/E1/J1 Media Converter Module Installation Instructions 17 Module Installation Instructions, Continued Installing the Prisma T1/E1/J1 Module Follow these steps to install the Prisma T1/E1/J1 module in a Prisma MediaCenter chassis or Prisma MediaCPE chassis. CAUTION: RJ-48 connectors are not for use with telephone networks. If used in this manner, damage to the telephone network may result. 1. Turn the chassis power switch to OFF and disconnect the chassis from the power source. 2. Remove the blank bracket (if present) covering the slot where the module is to be installed by removing the screws on the outside edges of the bracket. 3. Slide the module into the chassis using the card guides until the module is seated securely in the connector. 4. Secure the module to the chassis by tightening the captive screw(s). Note: Save any “blanks” removed during installation for future use should your configuration requirements change. 18 Prisma T1/E1/J1 Media Converter Module Installation Instructions 4008217 Rev B Fiber Optic Cleaning Guidelines Cleaning Optical Connectors Cleaning fiber-optic connectors can help prevent interconnect problems and therefore aid system performance. When optical connectors are disconnected and reconnected, the fiber surface can become dirty or scratched. The goal of cleaning the fiber optic connectors is to remove all dust and contaminants without leaving any residue. Required Equipment The following equipment is required to clean the ends of fiber-optic connectors. • Optical-grade (91%) isopropyl alcohol • Lint-free wipes • Compressed air (also called “canned air”) Tips for Optimal Fiber-Optic Connector Performance Follow these guidelines to ensure optimal connector performance. • Connect or disconnect optical connector performance. • Always use compressed air before cleaning the fiber-optic connectors. • Use end caps on connectors when they are not in use. • Always use compressed air to clean the end caps. • Use optical-grade isopropyl alcohol of at least 91% or greater. Anything less than 91% isopropyl may leave a film on the fiber surface, creating more problems. • Do not contaminate your alcohol supply. − Use a sprayer (a fountain pump is also adequate) − Do not put used alcohol back into the main container • Use only lint-free wipes. Never use “Kleenex-type” tissues. • If you have any degraded signal problems, clean the fiber-optic connector. Continued on next page 4008217 Rev B Prisma T1/E1/J1 Media Converter Module Installation Instructions 19 Fiber Optic Cleaning Guidelines, Continued Cleaning Optical Connectors Follow these steps to clean an optical connector. 20 1. Remove loose dirt or dust from the end of the connector by using compressed air (canned air) to blow dirt off the fiber and the connector. 2. Dampen a lint-free wipe with optical-grade isopropyl alcohol. If no wipes are available, use ferrule cleaner, part number 468517. 3. Clean the end of the connector using the lint-free wipe or ferrule cleaner. 4. Inspect the end of the connector for obvious contamination. 5. Mate the connector with an adapter or cover with an end cap.

LEDs Near the Untwisted-Pair Port The module front panel contains the following LEDs near the untwisted-pair port. Untwisted-Pair LED Description LPBK • Glows green when module is in Loopback mode. NO LNK • Glows green when a link is NOT established. PBEO • When Transmit Data Source is set to pseudorandom bit sequence, this LED glows yellow when Prisma T1/E1/J1 module receives a pseudorandom bit sequence with errors. • The LED stays off when the converter receives a pseudorandom bit sequence without errors. • When Transmit Data Source is set to any other configuration besides pseudorandom bit sequence, this LED remains off as well. Continued on next page 4008217 Rev B Prisma T1/E1/J1 Media Converter Module Installation Instructions 21 Module LED Indicators, Continued LEDs Next to the Fiber Optic Port The module front panel contains the following LEDs next to the fiber optic port. Fiber Optic LED Description NRZ • Glows green when NRZ is enabled. RM • Glows green on the remote unit when Remote Management is enabled. • Glows green on the local unit when it has discovered a manageable remote unit. 22 NO LNK • Glows green when a link is NOT established. SYM • Glows yellow when a symbol error has occurred. Prisma T1/E1/J1 Media Converter Module Installation Instructions 4008217 Rev B Troubleshooting General Troubleshooting • During installation, first test the fiber and UTP connections with all troubleshooting features disabled, then enable these features, if desired, just before final installation. This reduces the features’ interference with testing. • When working with units where the features cannot be disabled, you must establish BOTH your UTP and fiber connections; the NO LNK LEDs should not be lit (i.e., NO LNK LED not lit = good connection, NO LNK LED lit = problem). • To test a media converter by itself, first make sure you have an appropriate fiber patch cable, and then follow these steps to test. 1. Connect the media converter to the UTP device with a UTP cable. 2. Loop a single strand of fiber from the transmit port to the receive port of your media converter. Note: For single-strand fiber products, connect a single fiber cable from the local site Prisma T1/E1/J1 modules to a remote site’s Prisma T1/E1/J1 module. 3. Verify that you have a valid connection for both the twisted pair and fiber ports (see Module LED Indicators) on your media converter. Continued on next page 4008217 Rev B Prisma T1/E1/J1 Media Converter Module Installation Instructions 23 Troubleshooting, Continued Loopback Testing Prisma T1/E1/J1 modules include three loopback test modes: fiber digital loopback, twisted pair digital loopback and fiber analog loopback. A digital loopback test retransmits the signal after regenerating its bits and reconditioning the signal, while an analog loopback test simply redirects the incoming signal back out to the origin. The following illustration shows the path that a signal takes in each of the three loopback test modes. The following illustration shows the path that a signal takes in each of the three loopback test modes. Loopback testing aids in troubleshooting problems with network connections should they occur. “Looping" received data back onto the transmit path helps determine whether a connection is still valid. Twisted pair digital loopback tests isolate problems on the copper run between a T1/E1 converter and the connected device, while fiber digital loopback tests isolate problems on the fiber run. Continued on next page 24 Prisma T1/E1/J1 Media Converter Module Installation Instructions 4008217 Rev B Troubleshooting, Continued The following four illustrations show a typical progression of digital loopback tests; this series allows you to individually test each segment of the conversion. Start by checking the copper segment at the local side, then the copper segment at the remote side, etc. Continued on next page 4008217 Rev B Prisma T1/E1/J1 Media Converter Module Installation Instructions 25 Troubleshooting, Continued Testing with Pseudorandom Bit Sequence (PRBS) To test using pseudorandom bit sequence, configure the Prisma T1/E1/J1 modules for No Loopback, and then configure the Transmit Data Source to “Transmit Pseudorandom Bit Sequence”. Refer to DIP Switch Settings earlier in this document for all settings. Configure the local router for loopback, conduct the test, and then refer to the Module LED Indicators earlier in this document to verify errors were not received. 26 Prisma T1/E1/J1 Media Converter Module Installation Instructions 4008217 Rev B For Information If You Have Questions If you have technical questions, call SciCare™ Broadband Services for assistance.
