About the iMcV-DS3/E3/STS-LineTerm
iMcV-DS3/E3/STS-LineTerm is an SNMP manageable module that converts standard
thin coax signals ( DS3, E3/STS, STS ) 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 or MediaChassis
series, but can only be managed through a SNMP manageable iMediaChassis. DS3
Line Term modules must be configured as Host and Remote. To configure a module
as a Remote, set DIP Switch #10 to ON.
In addition, it is available with single-strand fiber: iMcV-DS3/E3/STS-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 as HOST and REMOTE must have opposite transmit and receive wavelengths
iMcV-DS3/E3/STS-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/STS-LineTerm unit.
Installation
iMcV-DS3/E3/STS-LineTerm modules can be installed in any iMediaChassis or
MediaChassis series, but can be managed only through the iMediaChassis. 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.
NOTE
It is not recommended that the iMcV-DS3/E3/STS-LineTerm module be installed in an IE-
MediaChassis/1-DC chassis (850-33100). The power source in this chassis is not isolated and
cannot support positive referenced ground systems typically used in Telco environments. The
IE-MediaChassis/2-DC and the iMediaChassis/6-DC are suitable alternatives.
