Bit 2: Transmit B8ZS Enable (TB8ZS).
0 = B8ZS encoding disabled
1 = B8ZS encoding enabled
Bit 1: Transmit Alarm Indication Signal (TAIS). Configuration bit TCR4.TAISM spe
cifies the type of AIS signal.
0 = Transmit data normally
1 = Transmit an unframed all-ones code at TPOS and TNEG
Bit 0: Transmit Remote Alarm Indication (TRAI). Configuration bit TCR4.T
RAIM specifies the type of RAI signal.
0 = Do not transmit remote alarm indication
1 = Transmit remote alarm indication
Register Name:
TCR1-E1
Register Description:
Transmit Control Register 1 (E1 Mode)
Register Address:
base address + 0x604
Bit # 7 6 5 4 3 2 1 0
Name TTPT T16S - TSiS TSA1 THDB3 TAIS TCRC4
Default 0 0 0 0 0 0 0 0
Bit 7: Transmit Timeslot 0 Pass Through (TTPT).
0 = FAS bits/Sa bits/Remote Alarm sourced internally from the TAF and TNAF re
gisters
1 = FAS bits/Sa bits/Remote Alarm sourced from the formatter’s TSER input
Bit 6: Transmit Timeslot 16 Data Select (T16S). See section 10.11.3.1.1..
0 = timeslot 1
6 determined by the TSSIE and THSCS regi
sters
1 = source timeslot 16 from the TS regi
sters
Bit 4: Transmit International Bit Select (TSiS).
0 = sample Si bits at formatter’s TSER input
1 = source Si bits from TAF and TNAF registe
rs (in this mode, TCR1-E1.TTPT must be set to 0)
Bit 3: Transmit Signaling All Ones (TSA1).
0 = normal operation
1 = force timeslot 16 in every frame to all-ones
Bit 2: Transmit HDB3 Enable (THDB3).
0 = HDB3 encoding disabled
1 = HDB3 encoding enabled
Bit 1: Transmit AIS (TAIS).
0 = transmit data normally
1 = transmit an unframed all-ones code at TPOS and TNEG
Bit 0: Transmit CRC-4 Enable (TCRC4).
0 = CRC-4 disabled
1 = CRC-4 enabled
