Advance Information
Per Channel Receive Signalling (Pages 9 and 0AH) (E1)
Page 09H, addresses 10001 to 11111, and page 1AH addresses 10001 to 11111 contain the Receive
Signalling Control Words for CAS channels 2 to 16 and 18 to 32. Table 137 illustrates the mapping between the
addresses of these pages and the CAS channel numbers. Table 138 describes bit allocation within each of
these registers.
Serial per channel receive signalling status bits appear on ST-BUS stream CSTo. Table 139 describes the bit
allocation within each of the 30 active ST-BUS time slot of CSTo.

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