Per Channel Transmit Signalling (Page 05H)
Table 62 describes Page 05H, addresses 11H to 1FH, which contains the Transmit Signalling Control Words for
PCM 30 channels 1 to 15 and 16 to 30. Control of these bits is through the processor or controller port when page
01H, address 1AH, bit 3, RPSIG = 1.
Serial per channel transmit signalling control through CSTi is selected when bit RPSIG is zero. Table 63 describes
the function of CSTi time slots 1 to 15, and Table 64 describes the function of CSTi 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.
