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.

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.
