Name
Functional Description
7
TXMSG
Transmit Message Mode. if high, the data from the corresponding address
location of Tx message mode buffer is transmitted in the corresponding PCM 30
time slot. If zero, the data on DSTI is transmitted on the corresponding PCM 30
time slot.
6
5
ADI
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.
RTSL
Remote Time Slot Loopback. If one, the corresponding PCM 30 receive time slot
is looped to the corresponding PCM 30 transmit time slot. This received time slot
will also be present on DSTO. If zero, the loopback is disabled.
4
3
LTSL
TTST
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 PCM 30 stream. If zero, this loopback is disabled.
Transmit Test. If one, a test signal, either digital milliwatt (when control bit ADSEQ
15
is one) or PRBS (2 -1) (ADSEQ is zero), will be transmitted in the corresponding
PCM 30 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.
2
RTST
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
15
channel. If ADSEQ is zero, the receive channel will be connected to the PRBS (2
- 1) detector
1
0
RPSIG
- - -
Serial Signaling Enable. If one, the transmit CAS signalling will be controlled by
programming Page 05H. If zero, the transmit CAS signalling will be controlled
through the CSTI stream.
Unused.
