Telecommunications systems consist of two dis- tinct areas of responsibility: the user side and the network side. Users interface their equipment to the network with some type of communications termi- nating equipment. Examples of these include multiplexers, channel banks, Tl CSUs and DSWCSUs. (Analog modems too, but this devel- opment focuses on digital communications.) The pur- pose of network terminating equipment is to con- vert the electrical (RS-232, V35 EIA-530, etc.) interface on the user's equipment to a 4-wire inter- face compatible with the carrier's digital network.
