Bit #
Name
The Transmit Channel Idle Code Enable Registers (TCICE1–4) are used to determine which of the 24 T1 channels
(or 32 E1 channels) from the backplane should be overwritten with the code placed in the Transmit Idle Code
Definition Register (TIDR1–32).
Bits 7 to 0: Transmit Channels 1 to 32 Code Insertion Control Bits (CH[1:32])

Register Description:
Register Address:
Bit #
Name
The Transmit Jammed Bit Eight Stuffing Registers (TJBE1–4) select which of the 24 T1 channels (or 32 E1
Channels) to insert jammed bit eight stuffing. These registers are enabled by TCR4.TJBEN.
Bits 7 to 0: Transmit Channels 1 to 32 Jammed Bit Eight Stuffing Control Bits (CH[1:32])
0 = Do not insert data from the Idle Code Array into the transmit data stream.
1 = Insert data from the Idle Code Array into the transmit data stream.
0 = Do not affect data in this channel.
1 = Replace the channel with TJBES if the channel is all zeros.
