Per Channel Receive Signalling (Page 06H)
Page 06H, addresses 11H to 1FH contain the Receive Signalling Control Words for PCM 30 channels 1 to 15 and
16 to 30.
Serial per channel receive signalling status bits also appear on ST-BUS stream CSTo. Table 66 describes the
function of CSTo time slots 1 to 15, and Table 67 describes the function of CSTo time slots 17 to 31, when page
01H, address 1CH, bit 1, MSN = 1. If MSN = 0, the signalling nibble appears at least significant bits (bits 3-0).

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.
Transmit Signalling Bits for Channel n + 15. These bits are
transmitted on the PCM 30 2048 kbit/sec. link in bit positions five to eight
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 + 15.
