Per Channel Receive Signaling (Pages 9 and 0AH) (E1)
Page 09H, addresses 10001 to 11111, and page 1AH addresses 10001 to 11111 contain the Receive Signaling
Control Words for CAS channels 2 to 16 and 18 to 32. Table 137 illustrates the mapping between the addresses of
these pages and the CAS channel numbers. Table 138 describes bit allocation within each of these registers.

Transmit Message Mode. If high, the data from the corresponding address
location of Tx message mode buffer is transmitted in the corresponding PCM30
time slot. If zero, the data on DSTI is transmitted on the corresponding PCM30 time
slot.
Alternate Digit Inversion. If one, the corresponding transmit time slot data on
DSTI has every second bit inverted. If zero, this bit has no effect on channel data.
Remote Time Slot Loopback. If one, the corresponding PCM30 receive time slot
is looped to the corresponding PCM30 transmit time slot. This received time slot will
also be present on DSTO. If zero, the loopback is disabled.
Local Time Slot Loopback. If one, the corresponding transmit time slot is looped
to the corresponding receive time slot. This transmit time slot will also be present on
the transmit PCM30 stream. If zero, this loopback is disabled.
Transmit Test. If one, a test signal, either digital milliwatt (when control bit ADSEQ
is one) or PRBS (2
PCM30 time slot. More than one time slot may be activated at once. If zero, the test
signal will not be connected to the corresponding time slot.
Receive Test. If one, the corresponding DSTo time slot will be used for testing. If
control bit ADSEQ is one, a digital milliwatt signal will be transmitted into the DSTo
channel. If ADSEQ is zero, the receive channel will be connected to the PRBS (2
- 1) detector
Serial Signaling Enable. If one, the transmit CAS signaling will be controlled by
programming Page 05H. If zero, the transmit CAS signaling will be controlled
through the CSTI stream.
