Register Address:
181h + (200h x (n - 1)) + (2000h x [(n - 1) / 8]): where n = 1 to 16
Bit
# 7 6 5 4 3 2 1 0
Name TTPT T16S TG802 TSiS TSA1 THDB3 TAIS TCRC4
Default
0 0 0 0 0 0 0 0
Note: See
for T1 Mode.
Bit 7: Transmit Time Slot 0 Pass Through (TTPT)
0 = FAS bits/Sa bits/Remote Alarm sourced internally from the
registers.
1 = FAS bits/Sa bits/Remote Alarm sourced from TSERn.
Bit 6: Transmit Time Slot 16 Data Select (T16S). See Section
on software signaling.
0 = Time slot 16 determined by the
–4 and
–4 registers.
1 = Source time slot 16 from
–16 registers.
Bit 5: Transmit G.802 Enable (TG802). See Section
.
0 = Do not force TCHBLKn high during bit 1 of time slot 26.
1 = Force TCHBLKn high during bit 1 of time slot 26.
Bit 4: Transmit International Bit Select (TSiS)
0 = Sample Si bits at TSERn pin.
1 = Source Si bits from
and
registers (in this mode,
.7 must be set to 0).
Bit 3: Transmit Signaling All Ones (TSA1)
0 = Normal operation.
1 = Force time slot 16 in every frame to all ones.
Bit 2: Transmit HDB3 Enable (THDB3)
0 = HDB3 disabled.
1 = HDB3 enabled.
Bit 1: Transmit AIS (TAIS)
0 = Transmit data normally.
1 = Transmit an unframed all-ones code at TTIPn and TRINGn.
Bit 0: Transmit CRC-4 Enable (TCRC4)
0 = CRC-4 disabled.
1 = CRC-4 enabled.
