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 zero, the internally calculated bit interleaved parity
value is inserted in the B1 bit position. If the OR results in a logic one, 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 zero, the F1 bit position is determined by the SPLT F1
Octet Register. If the OR results in a logic one, 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 zero, the Zn bit position is forced to a logic zero. If the OR results in a logic one, the Zn
bit position is inserted with the value sampled on TPOH.
