Receive Line Interface Selection: The receive line interface for channel
n is selected according to the following table:
RnLINT1
Receive Line Interface High Z or 0 Selection: Enabled only when the
RnLINT1 and RnLINT0 controls bits are set to 00. A 0 forces the line inter-
face output signals to a high Z state. A 1 forces the line interface output
signals to the 0 state. The TU/VT must be selected to drive the receive
output low. If using Single Unidirectional Ring mode, forcing outputs to
zero state is inhibited.
Receive Line Rate Selection: A 1 selects the E1 line rate for channel n. A
0 selects the DS1 line rate.
REI and RDI Disabled: Enabled when the single unidirectional mode
(control bits TnSEL1, TnSEL0 are equal to 01) is selected. A 1 disables
receive side alarms or an out of range condition from generating RDI. In
addition, the REI value is transmitted as a zero.
Channel n A/B Drop/Add Bus Selection: The table below lists the selec-
tion criteria for the eight available modes of operation of channel n:
Not used:
Transmit VT/TU Overhead Byte Selection: Enabled with the VT/TU
transmit line interface is selected. A 0 enables the output clock TVTCn to
be gapped during the four overhead byte times. A 1 enables the clock to
be symmetrical. Except for bits 1 and 2 in the K4 byte, the remaining bits
in the four overhead bytes are ignored.
Transmit Single Bit RDI Enable: A 1 configures the A and B add sides
for channel n for single bit RDI operation. A 0 configured add channel for
three bit RDI.
