Data Sheet
NOTE: This table illustrates bit mapping on the serial input stream - it does not refer to an internal register.
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 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.
