Default
Bit 0/Transmit CRC4 Enable (TCRC4)
Bit 1/Transmit G.802 Enable (TG802). See Section
Bit 2/Transmit HDB3 Enable (THDB3)
Bit 3/Transmit Signaling All Ones (TSA1)
Bit 4/Transmit International Bit Select (TSiS)
Bit 5/Transmit Unframed All Ones (TUA1)
Bit 6/Transmit Time Slot 16 Data Select (T16S). See Section
Bit 7/Transmit Time Slot 0 Pass-Through (TFPT)
0 = CRC4 disabled
1 = CRC4 enabled
0 = do not force TCHBLK high during bit 1 of time slot 26
1 = force TCHBLK high during bit 1 of time slot 26
0 = HDB3 disabled
1 = HDB3 enabled
0 = normal operation
1 = force time slot 16 in every frame to all ones
0 = sample Si bits at TSER pin
1 = source Si bits from TAF and TNAF registers (in this mode, E1TCR1.7 must be set to 0)
0 = transmit data normally
1 = transmit an unframed all-ones code at TPOSO and TNEGO
0 = time slot 16 determined by the SSIEx registers and the THSCS function in the PCPR register
1 = source time slot 16 from TS1 to TS16 registers
0 = FAS bits/Sa bits/remote alarm sourced internally from the TAF and TNAF registers
1 = FAS bits/Sa bits/remote alarm sourced from TSER
