BB Loop Back
Status: Programs the modem for baseband loopback operation (test mode).
When baseband loopback is turned on, the data and timing signals
are hard-wired (via relays) from the demodulator to the modulator on
the modem side of the interface. The DTE baseband signals are also
looped back from the transmitter data and clock to the receiver data
and clock on the customer side of the interface. This is a
bi-directional loopback of the baseband data. Refer to Figure 3-28 for
a block diagram of baseband loopback operation.
