• Manufacturer Part Number: mt9074ap1
• Description: T1/e1/j1 Single Chip Transceiver With Wide Dynamic Range Liu
• Manufacturer: Zarlink Semiconductor

Serial per channel transmit signaling control through CSTI is selected when RPSIG bit is zero. Table 132 describes
the function of CSTI time slots 1 to 30. if MSN bit is high, CSTI time slots 17 to 31 are selected. if MSN bit is low,
CSTI time slots 1 to 15 are selected.
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
(when n = 1 to 15), and are the A, B, C, D signaling bits associated with channel n.
