Signaling Bit A in Channel 24

TS1.0
Signaling Bit D 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 DS2152
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 3ms to update the TSRs. In the D4 framing mode, there are only 2
signaling bits per channel (A and B). However, in the D4 framing mode the DS2152 uses the C and D bit
positions as the A and B bit positions for the next multiframe. The DS2152 will load the values in the
TSRs into the outgoing shift register every other D4 multiframe.
7.2 HARDWARE BASED SIGNALING
7.2.1 Receive Side
In the receive side of the hardware based signaling, there are two operating modes for the signaling
buffer: signaling extraction and signaling reinsertion. Signaling extraction involves pulling the signaling
bits from the receive data stream and buffering them over a four multiframe buffer and outputting them in
a serial PCM fashion on a channel-by-channel basis at the RSIG output. This mode is always enabled. In
this mode, the receive elastic store may be enabled or disabled. If the receive elastic store is enabled, then
the backplane clock (RSYSCLK) can be either 1.544 MHz or 2.048 MHz. In the ESF framing mode, the
ABCD signaling bits are output on RSIG in the lower nibble of each channel. The RSIG data is updated
once a multiframe (3 ms) unless a freeze is in effect. In the D4 framing mode, the AB signaling bits are
output twice on RSIG in the lower nibble of each channel. Hence, bits 5 and 6 contain the same data as
bits 7 and 8 respectively in each channel. The RSIG data is updated once a multiframe (1.5 ms) unless a
freeze is in effect. See the timing diagrams in Section 15 for some examples.
The other hardware based signaling operating mode called signaling reinsertion can be invoked by setting
the RSRE control bit high (CCR4.7=1). In this mode, the user will provide a multiframe sync at the
