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.

Per Time Slot Control Words(Pages 7 and 8) (E1)
The control functions described by Table 135 are repeated for each PCM-30 channel. Page 07H addresses
10H to 1FH correspond to time slots 0 to 15, while page 08H addresses 10H to 1FH correspond to time slots
16 to 31.Table 136 illustrates the mapping between the addresses of these pages and the CEPT channel
numbers.
