About the iMcV-DS3/E3-LineTerm
iMcV-DS3/E3-LineTerm™ is an SNMP manageable module that converts standard
thin coax signals ( DS3, E3, STS-1 ) to a single-mode or multi-mode fiber signal. It
performs the standard “LineTermination” (GR-820-CORE) function of these TDM-
based line signals. This function transmits an Alarm Indication Signal (AIS) on the line
whenever a 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 pair of BNC connectors and one pair of ST or SC fiber
optic connectors. This module can be installed in any iMediaChassis™, MediaChassis
or iMediaCenter™ chassis but can only be managed through a SNMP manageable
iMediaChassis™.
In addition, it is available with single-strand fiber and the iMcV-DS3/E3-LineTerm
BNC/SSFX modules allow two wavelengths (1310 nm and 1550 nm) to share one
fiber strand, essentially doubling the capacity of installed fiber. The single-strand
versions at HOST and REMOTE must have opposite transmit and receive wavelengths
For example, one that transmits at 1310 nm must be paired with another that
receives at 1310 nm.
iMcV-DS3/E3-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-DS3/E3-LineTerm unit.
Configuration
Proper configuration of the iMcV-DS3/E3-LineTerm is required for maximum
performance and reliability. The following sections describe the prerequisites and the
configurations available for both managed and unmanaged modules.
Prerequisites
The iMcV-DS3/E3-LineTerm conforms to many DS3/E3/STS-1-based environments.
Ensure all of the relevant information about the expected installation environment is
available before configuring the module. This information includes
•
Distance of the coax run (450 feet MAX)
•
Distance of the fiber run (Must match fiber transceiver selected)
•
Troubleshooting requirements
