• Description: E1 Single Chip Transceiver
• Manufacturer: Mitel Networks Corporation

Preliminary Information
Per Channel Transmit Signalling (Page 05H)
Table 62 describes Page 05H, addresses 11H to 1FH, which contains the Transmit Signalling Control Words for
PCM 30 channels 1 to 15 and 16 to 30. Control of these bits is through the processor or controller port when
page 01H, address 1AH, bit 3, RPSIG = 1.
Serial per channel transmit signalling control through CSTi is selected when bit RPSIG is zero. Table 63 describes
the function of CSTi time slots 1 to 15, and Table 64 describes the function of CSTi time slots 17 to 31, when page
01H, address 1CH, bit 1, MSN = 1. If MSN = 0, the signalling nibble appears at least significant bits (bits 3-0).

Table 62 - Transmit Channel Associated Signalling

Table 63 - Transmit CAS Channels 1 to 15 (CSTi)
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.
Unused.
Transmit Signalling Bits for Channel n + 15. These bits are
transmitted on the PCM 30 2048 kbit/sec. link in bit positions five to eight
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 + 15.
