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 front panel, shown in Figure 1, includes:
• Electrical and optical connectors
• Reset switch
• LEDs for:
• System status
• Configuration
• Electrical signal

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.
