Access Multiplexer for 4x ISDN (S0) Chapter 1 General Information The AMX4S0 (4x ISDN Access Multiplexer) is a fiber modem for the conversion of 4 independent electrical S0 interfaces to an optical interface. The operation of the ISDN interfaces as TE or NT can be set with a DIP switch. This allows the user to either connect two telecommunication installations (cross connection) or extend existing ISDN S0 buses for ISDN telephones. Optionally, the S0 buses can be supplied separately, individually and short circuit-proof with 40V S0 supply voltage. For the transmission via optical fiber cables, various fiber optic modules with a transmission range of up to 60 km are available on special request.

User Manual
Status and control elements: Clearly visible LEDs indicate the presence of power, link activity, and status of the terminal device, loop and error status. Speed and operating mode of the individual interfaces can be set with DIP-switches ”MODE“.
Optical interface: The optical interface can also be found on the front panel of the AMX4S0. Depending on the device model, it allows the connection to multimode or single-mode optical fiber.
Front Panel View
S0 interfaces: The physical connections for the available S0 interfaces are on the back panel. The device is powered via adapter (lockable connector).
Back Panel View 19“ panel frame 1 HE: Dimensions (HxWxD): 4,4 x 48,3 x 0,3 cm One 1-HE panel frame can accommodate up to 3 desktop units. For assembly, remove the plastic panel in front and mount the desktop unit by using the 4 screws included in the delivery.

Interfaces
The following interfaces are available: o The LINK interface is for connection to the optical fiber network o 4 x ISDN S0 interfaces o Power to the AMX4S0 is supplied via the power socket. The socket is equipped with a locking mechanism to prevent accidental unplugging of the adapter.

The clock frequency is forwarded from the telecommunication installation via the optical fiber link to the ISDN terminal devices connected.
Setting of the DIP switches in location (1) with the telecommunication installation (PABX) must be as follows: Setting
Function TE configuration (S0 I/F 1-4)
Setting of the DIP switches in location (2) with ISDN phone must be as follows:

Function NT configuration (S0 I/F 1-4)
CAUTION! As the ISDN S0 interfaces here are operating in NT-MODE, the ISDN S0 cross cable (blue cable) must be used.
Chapter 4 Safety Regulations Only qualified persons should install AMX4S0. Do not open the aluminum housing or the wall plug adapters. Warranty is void if seals are broken. Keep FiberSprinter-S0 dry and clean. Please use the dust covers for the optical interfaces if no fiber is connected to it. Arcutronix AMX4S0 optical systems use semiconductor lasers as transmission sources. Infrared laser beam is invisible and has the potential to harm your eyes. You should be aware of corresponding laser safety regulations. Avoid looking into the laser beam from a short distance. All of arcutronix AMX4S0 series are Class 1 laser systems in accordance with international laser safety standard IEC/EN 825-1.
