About the iMcV-T1/E1/J1-LineTerm iMcV-T1/E1/J1-LineTerm is an SNMP-Manageable module that convert standard TDM-based copper transports ( T1, E1, J1) to a single-mode or multi-mode fiber signal. It performs a standard “Line Termination” function as defined in GR-820CORE. This function transmits an Alarm Indication Signal (AIS) on the line whenever the received signal is lost.
Prerequisites The iMcV-T1/E1/J1-LineTerm conforms to any T1/E1/J1-based environment. Ensure all of the relevant information about the expected installation environment is available before configuring the module.
Managed Modules The iMcV-T1/E1/J1-LineTerm modules are installed as a HOST-REMOTE pair and can be remotely managed when the HOST is installed in an iMediaChassis with an SNMP Management module. For a managed environment, first manually configure the desired features through DIP Switch settings to ensure this configuration is maintained if management is ever lost.
Unmanaged Modules Before installing the module in an unmanaged chassis, manually configure all of the desired DIP Switch selectable features. Modules must be configured as a HOSTREMOTE pair via DIP Switches. Modules are shipped in the default setting as a HOST. HOST: S3-2 OFF REMOTE: S3-2 ON DIP Switches The iMcV-T1/E1/J1-LineTerm DIP Switches are located on S2 and S3 on the PCB.

This feature can be controlled by SNMP–Management software (iView2) when the HOST iMcV-T1/E1/J1-LineTerm module is installed in a managed chassis. Fault Loopback This switch enables or disables the Fault Loopback feature on the copper port. A normal copper line fault LOS will cause Remote Alarm Indictor (RAI) to be sent on to the fiber line segment causing the normal AIS to be sent on the far end copper port. This feature provides for a fault indication to be sent back to the copper line as an AIS signal.
This feature can be controlled by SNMP-Management software (iView2) when the HOST iMcV-T1/E1/J1-LineTerm module is installed in a managed chassis. T1, E1 and J1 Selection This switch selects the data rate to use on the copper line. The data rate selections available include the following: • • T1/J1 (1.544 Mbps +/- 32 ppm) E1 (2.048 Mbps +/- 32 ppm) By default this feature is set to T1. This feature can be selected only by setting the DIP Switches manually.
LED Operation The iMcV-T1/E1/J1-LineTerm module features several diagnostic LEDs per port. The following LED display functions are provided: Copper Port LEDs ER LOS PRBS TEST Flashes yellow whenever a line code violation is received. Glows red when the RJ-48 is receiving no signal and is in an LOS ALARM state. This condition will also send an RAI signal to the fiber port. If the Fault Loopback is set to ON, an AIS will also be sent to the local copper port.
Loopback Testing The iMcV-T1/E1/J1-LineTerm includes three Loopback test modes: Copper Loopback, Fiber Loopback and Internal Fiber Loopback. The following illustrations show the path that a signal takes in each of the Loopback test modes. Each Loopback performs the following: • Copies the incoming signal back out to the origin while continuing to transmit this signal downstream. • Blocks upstream data from transmitting on the looped data line.

Installation Troubleshooting General Troubleshooting • The copper port can easily be tested using the internal PRBS signal generator and detector and a physical wire loop on the copper interface. • The fiber port is internally tested at all times by a working pair of units. With one unit configured for Local Management (S3-2 set OFF) and the other for Remote Management (S3-2 set ON), the fiber line is verified if the RM LED is ON at both ends of the fiber line.

Fiber Optic Cleaning Guidelines Fiber Optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust, which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules. 1. Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier; low-quality components can cause many hard-to-diagnose problems in an installation. 2.
