NAME AND DESCRIPTION
Signaling Bit D in Channel 24
A(1)
TS1.0
Signaling Bit A in Channel 1
Each Transmit Signaling Register (TS1 to TS12) contains the Robbed-Bit signaling for eight DS0
channels that will be inserted into the outgoing stream if enabled to do so via TCR1.4. In the ESF
framing mode, there can be up to 4 signaling bits per channel (A, B, C, and D). On multiframe
boundaries, the DS2151Q will load the values present in the Transmit Signaling Register into an outgoing
signaling shift register that is internal to the device. The user can utilize the Transmit Multiframe
Interrupt in Status Register 2 (SR2.6) to know when to update the signaling bits. In the ESF framing
mode, the interrupt will come every 3 ms and the user has a full 3 ms to update the TSRs. In the D4
framing mode, there are only 2 framing bits per channel (A and B). However in the D4 framing mode,
the DS2151Q uses the C and D bit positions as the A and B bit positions for the next multiframe. The
DS2151Q will load the values in the TSRs into the outgoing shift register every other D4 multiframe.
8.0 SPECIAL TRANSMIT SIDE REGISTERS
There is a set of seven registers in the DS2151Q that can be used to custom tailor the data that is to be
transmitted onto the T1 line, on a channel by channel basis. Each of the 24 T1 channels can be either
forced to be transparent or to have a user defined idle code inserted into them. Each of these special
registers is defined below.
