General Description
The Kentrox D-SERV DSU/CSU is a low cost, intelligent, single port
T1 DSU/CSU that provides channelized connections to T1 or
Fractional T1 (FT1) services. The serial data signal can operate in
increments of 56 Kbit/s or 64 Kbit/s, up to the full band width of
1.536 Mbit/s. The network T1 signal is always 1.544 Mbit/s. The CSU
portion of the D-SERV DSU/CSU insures that the signal is compatible
in format and pulse density with T1 requirements. The D-SERV
DSU/CSU provides line protection from voltage spikes, surges and
line crossings coming from the public network. In addition, the
D-SERV DSU/CSU generates alarm signals and performs loop backs
to aid in the turn up and trouble-shooting of expensive T1 circuits.
