SRCG1:

The SRCG1 bit value ORed with input TPOHINS selects the source for the

G1 octet on a bit by bit basis. If the OR results in a logic 0, the G1 bit position

is derived internally as required. If the OR results in a logic 1, the G1 bit

position is inserted with the value sampled on TPOH.

SRCB1:

The SRCB1 bit value ORed with input TPOHINS selects the source for the B1

octet on a bit by bit basis. If the OR results in a logic 0, the internally

calculated bit interleaved parity value is inserted in the B1 bit position. If the

OR results in a logic 1, the B1 bit position is inserted with the value sampled

on TPOH.

SRCF1:

The SRCF1 bit value ORed with input TPOHINS selects the source for the F1

octet on a bit by bit basis. If the OR results in a logic 0, the F1 bit position is

determined by the SPLT F1 Octet Register. If the OR results in a logic 1, the

F1 bit position is inserted with the value sampled on TPOH.

SRCZN:

The SRCZN bit value ORed with input TPOHINS selects the source for the Zn

octets (where n=1 to 4 for the DS1 or E1 PLCP frame formats, n=1 to 6 for

the DS3 PLCP frame format, and n=1 to 3 for the G.751 E3 PLCP frame

format) on a bit by bit basis. If the OR results in a logic 0, the Zn bit position

is forced to a logic 0. If the OR results in a logic 1, the Zn bit position is

inserted with the value sampled on TPOH.
