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 (within
the XRT75R03) into various loop-back modes.
The relationship between the settings for this input pin, the
corresponding LLB_n bit-field and the resulting Loop-back
Mode is presented below.

E3 Mode Select - Channel_n:
This READ/WRITE bit-field, along with Bit 1 (STS-1/
DS3_n) within this particular register, is used to configure a
given channel (of the XRT75R03) into either the DS3, E3
or STS-1 Modes, as depicted below.
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.
