SYMBOL
POSITION NAME AND DESCRIPTION
THE
TDC1.7
Transmit HDLC Enable.
0 = disable HDLC controller (no data inserted by HDLC controller into
the transmit data stream)
1 = enable HDLC controller to allow insertion of HDLC data into either
the Sa position or multiple DS0 channels as defined by TDC1 (see bit
definitions below).
TSaDS
TDC1.6
Transmit Sa Bit / DS0 Select. This bit is ignored if TDC1.7 is set to zero.
0 = route Sa bits from the HDLC controller. TD0 to TD4 defines which Sa
bits are to be routed. TD4 corresponds to Sa4, TD3 to Sa5, TD2 to Sa6,
TD1 to Sa7 and TD0 to Sa8.
1 = route DS0 channels from the HDLC controller. TDC1.5 is used to
determine how the DS0 channels are selected.
