Per Channel Transmit Signalling (Page 5)
Table 12 describes Page 05H, addresses 10001 to
11111, 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 the RPSIG bit is high.
After a RESET or RST function, this page will be
deselected (CSTi2 selected). RPSIG must be made
high before the page can be programmed.
Serial per channel transmit signalling control through
CSTi2 is selected when RPSIG is low. Table 13
describes the function of ST-BUS time slots 1 to 15,
4-258

Transmit Signalling Bits for Cha nnel
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 associ-
ated with channel n.
Transmit Signalling Bits for Cha nnel
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.
