NAME AND DESCRIPTION
TUA1
TCR.7
Transmit Unframed All 1’s.
0 = Normal operation.
1 = Replace outgoing data at TPOS and TNEG with unframed all
1’s code.
TSS
TCR.6
Transmit Signaling Select
1
0 = Signaling data embedded in the serial bit stream is sampled at
TSER during timeslot 16.
1 = Signaling data is channel associated and sampled at TSD as
shown in Table 6.
TSM
TCR.5
Transmit Signaling Mode
1
0 = Channel Associated Signaling (CAS).
1 = Common Channel Signaling (CCS).
INBS
TCR.4
International Bit Select
0 = Sample international bit at TIND.
1 = Outgoing international bit = TINR.7.
NBS
TCR.3
National Bit Select
0 = Sample national bits at TIND.
1 = Source outgoing national bits from TINR.4 through TINR.0.
XBS
TCR.2
Extra Bit Select
0 = Sample extra bits at TXD.
1 = Source extra bits from TXR.0 through TXR.1 and TXR.3.
TSA1
TCR.1
Transmit Signaling All 1’s
0 = Normal operation.
1 = Force contents of timeslot 16 in all frames to all 1’s.
ODM
TCR.0
Output Data Mode
0 = TPOS and TNEG outputs are 100% duty cycle.
1 = TPOS and TNEG outputs are 50% duty cycle.
