Overview
The Model 2345 managed T3 fiber optic modem with Optical Line Interface Module (OLIM) extends
T3 (44.736 Mbps) signals between devices located up to 120 Km apart. The OLIM supports
multimode and single mode fiber. Use the modem to extend a PBX, router, video codec, DS3
multiplexer, or ATM switch.
The 2345 transports B3ZS or AMI coded data. The 2345 supports both framed and unframed modes.
Framed mode supports C-bit Parity or M-13 framing patterns, can correct polarity errors, and gathers
DS3 statistics. Unframed mode passes data with full transparency.
The 2345 can be used in a UCS 1000 or UCS 1001 chassis or directly as a standalone.
•
The UCS 1000 Chassis can hold up to 15 model 2345 modems; you can manage each 2345 either
directly through the serial port or through the Domain Management Module (DMM) within the
domain.
Note: The Chassis Interconnect Module (CIM) must be present in the UCS 1000 chassis in order
for the DMM to recognize the 2345 modules.
•
The UCS 1001 Chassis can hold up to two model 2345 modems; you can manage each 2345
directly through the serial port.
•
The standalone 2345 provides one modem that you can manage directly through the serial port.
The 2345 is hot swappable; you can insert or remove it at any time without disrupting the data
transfer of other modules in the chassis.
