Serial per channel receive signaling status bits appear on ST-BUS stream CSTo. Table 136 describes the bit
allocation within each of the 30 active ST-BUS time slot of CSTo. Depending on the state of MSN bit (Page 1, 14H)
either lower or higher signaling nibble is used.

Receive Signaling Bits for Channel n. These bits are received on the PCM30
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 signaling bits associated with channel n.
Transmit Signaling Bits for Channel n. These bits are transmitted on the PCM30
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 signaling bits associated with channel n.
