Co-Located Terminals

Any combination of subchannel DTE devices and subchannel DCE devices is possible. For example, local subchannel terminals can be co- located with modes that communicate with devices at remote sites. Fig- ure 1-3 shows an example of co-located terminals in the port-sharing mode. Co-location of ports and modems is also possible in the modem- sharing mode.

Cascading the 2185

The 2185 can be cascaded to increase the number of channels connected to the main channel controller. Cascading is accomplished by connect- ing the main channel of one unit to a subchannel of another unit. See Figure 1-4.
