T1 Access Unit with High Speed Data, FXS and E&M
In the example shown in the following diagram, data and regular voice traffic are
transported by the T1 access unit and the APL modem. E&M-type voice (in
Transmit mode only) is being used to transport the APL modem traffic, while FXS
is employed to transmit regular voice traffic.
Another variation of this application would have the lines connected to the
telephones terminate at a switch in the cloud, where they could be connected to
any other telephone in the world.
