Per Channel Transmit Signalling (Pages 5 and 6) (E1)
Page 05H, addresses 10000 to 11111, and page 06H addresses 10000 to 10111 contain the Transmit
Signalling Control Words for Channel Associated Signalling (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.
Serial per channel transmit signalling control through CSTI is selected when RPSIG bit is zero. Table 132
describes the function of CSTI time slots 1 to 30. if MSN bit is high, CSTI time slots 17 to 31 are selected. if
MSN bit is low, CSTI time slots 1 to 15 are selected.

Transmit Signalling Bits for Channel n.
These bits are transmitted on the PCM
30 2048 kbit/sec. Link in bit positions one to four of time slot 16 in frame n (when
n = 1 to 15), and are the A, B, C, D signaling bits associated with channel n.
