SPE_TSTS3TMSLOT[1:0]
Transmit STS-3 Time-Slot Value.
Two-bit value
selects one of three STS-1 time slots within an STS-3
in the transmit direction.
00 = No output.
01 = STS-1/TUG-3 data for slot 1 in STS-3/STM-1.
10 = STS-1/TUG-3 data for slot 2 in STS-3/STM-1.
11 = STS-1/TUG-3 data for slot 3 in STS-3/STM-1.
Receive STS-1 Mode.
When 1, STS-1 mode is
selected for receive data. When 0, STS-3/STM-1.
Receive Serial STS-1 SPE Mode.
When 1, serial data
demapped from STS-1 SPE is sent out to an external
serial interface.
Receive DS3 Output Type.
Two-bit value selects one
of three DS3 output devices.

SPE_RDS3OUTTYP[1:0]
00 or 01 = DS3 data to M13 block.
10 = DS3 data to loopback (RX to TX).
11 = DS3 data to external clear channel.
Receive VT or DS3 Output.
When 1, VT data is out-
put; when 0, DS3 data is output.
Receive AU-3/STS-1 or TUG-3 Demapping.
When 1,
AU-3/STS-1 demapping is selected; when 0, TUG-3
demapping is selected.

SPE_RSTS3TMSLOT[1:0]
Receive STS-3 Time Slot.
Selects one of three STS-1
time slots within an STS-3/STM-1 frame in the receive
direction.
00 = No selection.
01 = STS-1/TUG-3 data from slot 1 in STS-3/STM-1.
10 = STS-1/TUG-3 data from slot 2 in STS-3/STM-1.
11 = STS-1/TUG-3 data from slot 3 in STS-3/STM-1.
Transmit Serial Sync Position Within a Byte Bound-
ary.
Selects one of eight positions for the bit sync of the
serial transmit data stream (previously known as the
NSMI interface data).
Receive Serial Sync Position Within a Byte Bound-
ary.
Selects one of eight positions for the bit sync of the
serial receive data stream (previously known as the
NSMI interface data).
Reserved.
