SPE_T_STS1_MODE
Transmit STS-1 Mode.
When 1, STS-1 mode is
selected for transmit data; when 0, STS-3/STM-1.
Transmit Serial STS-1 SPE Mode.
When 1, serial
data is accepted through an external serial interface
and mapped to STS-1 SPE.
Transmit DS3 Source Type.
Two-bit value selects
one of three DS3 input sources.

SPE_TDS3SRCTYP[1:0]
00 or 01 = DS3 data from M13 block.
10 = DS3 data from loopback (Rx to Tx).
11 = DS3 data from external clear channel.
Transmit VT or DS3 Input.
When 1, VT input data is
selected; when 0, DS3 input data is selected.
Transmit AU-3/STS-1 or TUG-3 Mapping.
When 1,
AU-3/STS-1 mapping is selected; when 0, TUG-3 map-
ping is selected.
