Per Channel Transmit Signaling (Pages 5 and 6) (E1)
Page 05H, addresses 10000 to 11111, and page 06H addresses 10000 to 10111 contain the Transmit Signaling
Control Words for Channel Associated Signaling (CAS) channels 2 to 16 and 18 to 32 respectively. Table 132
illustrates the mapping between the addresses of these pages and the CAS channel numbers. Control of these bits
for any one channel is through the processor or controller port when the Per Time Slot Control bit RPSIG bit is high.
Table 133 describes bit allocation within each of these registers.

Errored Frame Alignment Signal Counter Overflow Latch. This bit is
set when the errored frame alignment signal counter overflows. It is
cleared after being read.
CRC Error Counter Overflow Latch. This bit is set when the crc error
counter overflows. It is cleared after being read.
E Bit Counter Overflow Latch. This bit is set when E bit counter
overflows. It is cleared after being read.
Bipolar Violation Counter Overflow Latch. This bit is set when the
bipolar violation counter overflows. It is cleared after being read.
Pseudo Random Bit Sequence Error Counter Overflow Latch. This
bit is set when the PRBS error counter overflows. It is cleared after being
read.
Pseudo Random Bit Sequence Multiframe Counter Overflow Latch.
This bit is set when the multiframe counter attached to the PRBS error
counter overflows. It is cleared after being read
Unused.
