As demand and bandwidth needs increase in today's telecommunications and data network. Large economies of scale can be achieved by substituting multiple single T1 trunks with a single DS3. A DS3 will reduce overall expenses and control costs by combining data and voice applications over one circuit. The benefits can be reaped as soon as you subscribe to more than 8 T1 circuits simultaneously.

The T3Mux is a M13 Multiplexer that interfaces with the DS3 network via two BNC coaxial connectors, one for Rx (Input) and one for Tx(Output). The T1 connectors are RJ48, there are two T1 ports per connector, each in a DSX pinout.
The T3Mux offers a simplified and user-friendly management console accessible via Ethernet or RS232. It features a VT100 terminal interface for system manage-ment, DS1 and DS3 Interface configuration.

Cables
All cables for the T3Mux are sold separately. Each of the 14 physical RJ45 ports on the device provide two separate T1 circuits via a splitter cable or direct connection to a Sangoma A108 card. The following cables are available:
- T3 coax cables (Tx and Rx pair) (CABL-646): For connecting DS3 circuit to the multiplexer
- Dual T1 port-splitter cable (CABL-630): For connecting each RJ45 connector on the multiplexer to two T1 circuits
- Standard T1 cable (CABL-614G): For connecting two T1 circuits between T3Mux and Sangoma A108 model cards
