Overview
The 2346 Managed T3 Fiber Optic Modem converts and extends T3/DS3 signals between devices
located up to 100 Km apart. Use the modem to extend a PBX, router, video codec, M13 multiplexer,
or ATM switch. The 2346 receives and transmits 44.736 Mbps data on single mode or multimode
fiber optic cable.

The 2346 can be used in a variety of chassis. To install a 2346 in a UCS 1000 or UCS 1001 chassis,
you must use a Model 1230 Bus Access Module (BAM); however, you can install a 2346 directly in a
UCS 1002 or standalone enclosure.
•
The UCS 1000 Chassis can hold up to 15 model 1230 BAMs with up to two 2346 modems per
BAM. This allows a total of 30 2346 modems per UCS 1000.
•
The UCS 1001 Chassis can hold up to two model 1230 BAMs with up to two 2346 modems per
BAM. This allows a total of four 2346 modems per UCS 1001.
•
The UCS 1002 Chassis directly hosts up to fourteen 2346 modems, or thirteen 2346 modems with
the optional Domain Management Module (DMM) installed.
•
Each standalone enclosure, such as a Model 1020 or 1030E, holds one 2346 modem.
The 2346 is hot swappable; you can insert or remove it at any time without disrupting the data
transfer of other modules in the chassis.
