Distributed Communications System (DCS)

Distributed Communications System (DCS) allows two or more switches to provide transparency

for certain attendant and voice terminal features as if the cluster were a single large switch. DCS

simplifies dialing procedures between locations and allows the use of some of the system’s

features between locations. To clarify this further, if you have two switches in the same company

that are networked together but do not have DCS, if a call from one display terminal is made to

another display terminal, the terminal receiving the call displays only the trunk line over which the

call was placed. If the switches have DCS, however, the extension from which the call is made

appears. Another example is that the Leave Word Calling button can be used where two

switches have DCS. Figure 4 shows how the DCS can be connected to the system.
