Baseband Modem TS7-G

The Multi Data Digital TS7-G digital service units/modems are probably the best performing, best value baseband products available today. A great deal of research has gone into the designing and production of these DSU/modems. The design is compact at just 7” x 4” yet resilient due to the RFI compliant metal casing. A full array of LED´s give indication of modem status at all times and to assist in trouble-shooting on any network a comprehensive range of diagnostic tests are also provided.

With the distances that the TS7-G can operate over they cannot be termed as “Short Haul” and indeed the TS7-G is particularly suited to 64,000 bps digital service provision over long distances either in-house or for PTT´s needing to link customer premises to local exchanges to provide “kilostream” facilities. The difference to the standard TS7-X is that, the TS7-G includes a G.703 interface to directly connect into transmission equipment and carry the 64 kbps signal up to 20 km further, either on 2 or 4 wires and provide a coherent clocking to the modem tail, synchronizing it with the network. In addition, the TS7-G can work with the TS7-X and the TS7-X-V, so the interface at the other end of the link must not be G.703 again.

For central site installations the TS16 provides the ideal solution. Any mix of TS6, TS7-X and TS7-G DSU’s, up to 16 units can be fitted. Like all Multi Data Digital high quality products the TS7-G and TS16 are also guaranteed for 2 years and technically supported for their lifetime.
