About the iMcV-T1/E1/J1 The iMcV-T1/E1/J1™ chassis mounted media conversion module allows you to extend the distances between T1, J1, and E1 copper telephony systems by adding a fiber segment. The distances you can add range from 2km to 100km depending on the module used and the fiber type available.
Configuration The iMcV-T1/E1/J1 module is factory-configured to use the following default features: • • • • • • • • • • • T1/E1 Mode.................................................................................................... T1 Receive Equalizer Gain Limit (EGL): .......................-30 dB (Limited Long Haul) Line Encoding: .................................................................... AMI (Passive Mode) Transmit LIU Waveshape (Build-out): ................
Available configurations enabled by DIP switches (and iView2): T1 Mode Configurations (default) E1 Mode Configurations • Receive Equalizer Gain Limit (EGL) iView2 o -36 dB (Long Haul) o -30 dB (Limited Long Haul) (default) • Line Encoding iView2 o B8ZS o AMI (default) • Transmit LIU Waveshape (Build-out) o DSX-1 (0 to 133 ft) 0 dB CSU (default) o DSX-1 (133 to 266 ft) o DSX-1 (266 to 399 ft) o DSX-1 (399 to 533 ft) o DSX-1 (533 to 655 ft) o -7.5 dB CSU o -15 dB CSU o -22.
Installation At the central location the iMcV-T1/E1/J1 unit is typically installed in a managed chassis such as the iMediaChassis or the iMediaCenter.
MediaChassis The MediaChassis provides a typical unmanaged chassis suitable for all remote installation locations. NOTE Chassis may also be available in Industrial Ethernet (IE) configurations. Each module requires one slot in the chassis. To install a module, remove the blank brackets covering the slots where the module is to be installed (if present) by removing the screws on the outside edges of the bracket.

Unmanaged Modules Before installing the iMcV-T1/E1/J1 module into an unmanaged chassis, configure the module hardware-selectable features via DIP switches located at position S3 and S2 on the PCB (refer to the DIP Switch Table section for more information). The jumpers located at positions JP1 and JP2 are factory configured— DO NOT CHANGE. Description of DIP Switch-Selectable Options The iMcV-T1/E1/J1 module includes movable DIP switches for hard switching the optional features.
Receive LIU Termination (Line Termination) This option allows you to set the receive termination. This is used to properly terminate cables in order to prevent signal reflections which can cause signal degradation. Transmit Data Source This option allows you to set the module to send normal data (default) or to send specific test-patterns of data to determine problems along the cable as a diagnostic tool.
Remote Management This option allows you to enable Remote management on the module. The remote management feature is designed to work only on the remote module of the Local/Remote pair. With Remote management enabled, you can easily perform the following: • • • Test the line integrity of the remote copper port. Use the Local unit to configure all SNMP-configurable features for both units. Use the Local unit to download firmware for both units.
Module LED Functions This section describes the LEDs and their functions. The Fiber port LED RM is the only LED that should be lit on the modules under normal operating conditions. Copper Port LEDs LPBK Glows green when the module is set to one of the Loopback modes. NO LNK Glows green when a UTP link is NOT established. PBEO Only used when the Transmit Data Source option is set to Pseudo-random Bit Sequence.
Testing To test a media converter by itself, first make sure you have an appropriate fiber patch cable, then perform the following steps: 1. Connect the media converter to the T1/E1 device with a standard UTP cable. If the NO LNK LED for the copper port remains on, you are not receiving a valid signal. Push the crossover push button on the front of the unit. Verify that the NO LNK LED for the copper port is off. 2.
The iMcV-T1/E1/J1 can be configured to use the following loopback test modes: • Local Fiber Loopback Mode This setting tests the path from the CO copper port to the Local iMcV-T1/E1/J1 module fiber port and back. • Remote Fiber Loopback Mode This setting tests the path from the CO copper port to the Remote iMcV-T1/E1/J1 module fiber port and loops it back. • Remote Copper Loopback Mode This setting tests the path from the CO copper port to the Remote iMcV-T1/E1/J1 module copper port and loops it back.
Remote Fiber Loopback Mode To set the loopback testing mode to Remote Fiber Loopback Mode, perform the following: 1. Set the Local iMcV-T1/E1/J1 module Loopback to None (DIP switch S3-3=On and S3-4=On) 2. Set the Remote iMcV-T1/E1/J1 module to Local Loopback (DIP switch S3-3=Off and S3-4=On). This configuration allows you to test the path from the CO copper port to the Remote iMcV-T1/E1/J1 module fiber port and loop it back. The transmitted data is sent unhindered and the received data is ignored.
Testing with Pseudorandom Bit Sequence (PRBS) To test the copper segment from the Remote module to the Customer Premises Equipment (CPE) by using PRBS, perform the following: 1. Set the CPE to loopback the signal. 2. Set the Remote module to generate PRBSs (DIP switch S2-9=On and S2-10=Off). Check the LEDs to verify errors are not received (refer to the Module LED Functions section for more information).
