S1REGEN
The S1 register enable (S1REGEN) bit controls the insertion of the synchronization status
message in the data stream. When S1REGEN is set to logic 1, the SSM from the TRMP
Transmit S1 and Z1 register is inserted in the S1 byte of STS-1/STM-0 #1 according to the
priority of Table 10. When S1REGEN is set to logic 0, the SSM from the TRMP Transmit
S1 and Z1 register is not inserted.
Z1REGEN
The Z1 register enable (Z1REGEN) bit controls the insertion of Z1 growth bytes in the data
stream. When Z1REGEN is set to logic 1, the Z1 byte from the TRMP Transmit S1 and Z1
register is inserted in the Z1 bytes according to the priority of Table 10. When Z1REGEN
is set to logic 0, the Z1 byte from the TRMP Transmit S1 and Z1 register is not inserted.
Z2REGEN
The Z2 register enable (Z2REGEN) bit controls the insertion of Z2 growth bytes in the data
stream. When Z2REGEN is set to logic 1, the Z2 byte from the TRMP Transmit Z2 and E2
register is inserted in the Z2 bytes according to the priority of Table 10. When Z2REGEN
is set to logic 0, the Z2 byte from the TRMP Transmit Z2 and E2 register is not inserted.
E2REGEN
The E2 register enable (E2REGEN) bit controls the insertion of line order wire in the data
stream. When E2REGEN is set to logic 1, the line order wire from the TRMP Transmit Z2
and E2 register is inserted in the E2 byte of STS-1/STM-0 #1 according to the priority of
Table 10. When E2REGEN is set to logic 0, the line order wire from the TRMP Transmit
Z2 and E2 register is not inserted.
NATIONALEN
The national enable (NATIONALEN) bit controls the insertion of national bytes in the data
stream. When NATIONALEN is set to logic 1, an all one or an all zero pattern is inserted
in the national bytes according to the priority of Table 10. When NATIONALEN is set to
logic 0, no pattern is inserted. The Z0DEF bit in the TRMP Configuration register defines
the national bytes of ROW #1.
NATIONALV
The national value (NATIONALV) bit controls the value inserted in the national bytes.
When NATIONALV is set to logic 1, an all one pattern is inserted in the national bytes if
enabled via the NATIONALEN register bit. When NATIONALV is set to logic 0, an all
zero pattern is inserted in the national bytes if enabled via the NATIONALEN register bit.
