The AUPC channel is MUXed onto the data and transmitted at an overhead rate of 16/15
of the main channel. The AUPC feature allows remote communication between a local
modem and a remote modem. Refer to Figure 10-1 for a modem block diagram with the
AUPC interface option. EIA-422, or V.35 interfaces are available for terrestrial data input
and output. These interfaces can be selected via the front panel.
