Telenetics 2185
•When operating with control signal contention, the 2185 is trans- parent to the data stream.
•When operating with data contention, subchannel data must be mark idle and 16 consecutive marks cannot appear in mid-mes- sage. The minimum data rate for an external clock is 50 bps.
Port-Sharing Mode
In the port-sharing mode, the 2185's main channel is connected directly to a CPU or controller port (DTE). Subchannel devices communicate with the 2185 via modem links. Figure 1-1 shows a typical port-sharing application.
