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.
