Loop-Back Select - RLB Bit - Channel_n:
This READ/WRITE bit-field along with the corresponding LLB_n bit-field is
used to configure a given channel into various loop-back modes ass shown
by the following table.
Loop-Back Select - LLB Bit-field - Channel_n:
See the table (above) for RLB_n.
E3 Mode Select - Channel_n:
This READ/WRITE bit-field, along with Bit 1 (STS-1/DS3_n) within this reg-
ister, is used to configure a given channel into either the DS3, E3 or STS-1
Modes.
0 - Configures Channel_n to operate in either the DS3 or STS-1 Modes,
depending upon the state of Bit 1 (STS-1/DS3_n) within this same register.
1- Configures Channel_n to operate in the E3 Mode.
