Description T1 channel does not contain frame control information, perform timeslot division, or
perform timeslot binding after it is configured to work in unframed mode. Its 24
timeslots and F-bit works as a path to form a serial interface at 1.544Mbit/s.
When the T1 channel is set to work in unframed mode, it does not include frame
control information and does not allow timeslot division or bundling. Its 24 timeslots
and F-bit form a 1.544 Mbps serial interface as a channel.
T1 commands are available with the CPOS(T) interface module but not with the
CPOS(E) interface module.
