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-820-
CORE. This function transmits an Alarm Indication Signal (AIS) on the line whenever
the received signal is lost. Line faults can easily be isolated to one line section and do
not propagate over multiple-line sections as they do with normal line repeaters.
Each module includes one RJ-48 connector and one pair of ST or SC fiber optic
connectors. These modules can be installed in any iMediaChassis but can only be
managed through the iMediaChassis. The iMcV-T1/E1/J1-LineTerm modules must be
deployed in pairs (one at each end of a fiber line). The data transmitted on the fiber
ports can only be received and interpreted by another iMcV-T1/E1/J1-LineTerm unit.
The iMcV-T1/E1/J1-LineTerm is also available with single-strand fiber allowing two
wavelengths (1310 nm and 1550 nm) to share one fiber strand, essentially doubling
the capacity of installed fiber. With the single-strand version, the HOST and
REMOTE must be ordered with opposite transmit and receive wavelengths for proper
operation.
Installation
The iMcV-T1/E1/J1-LineTerm modules can be installed in any iMediaChassis series.
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 by removing the
screws on the outside edges of the bracket. Slide the module into the chassis card
guides until the module is securely seated in the connector. Secure the module to
the chassis by tightening the captive screw. Save any blanks removed during
installation for future use.
Crossover/Straight-Through Connection
iMcV-T1/E1/J1-LineTerm comes with an RJ-48 UTP connector that features a push-
button switch, located next to the port, for selecting a crossover connection, push-
button IN. A straight-through connection is selected when the push-button is OUT.
When unsure what type of connection is needed, set the push button to the position
that turns the LOS LED off.
Configuration
Proper configuration of the iMcV-T1/E1/J1-LineTerm is required for maximum
performance and reliability. The following sections describe the prerequisites and the
configurations available for both managed and unmanaged modules.
