SATURN USER NETWORK INTERFACE FOR 2488 MBIT/S
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 4. 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
4. 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 4. 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 enable via
the NATIONALEN register bit. When NATIONALV is set to logic 0, an all zero pattern is
inserted in the national bytes if enable via the NATIONALEN register bit.
UNUSEDEN:
The unused enable (UNUSEDEN) bit controls the insertion of unused bytes in the data
stream. When UNUSEDEN is set to logic 1, an all one or an all zero pattern is inserted in the
unused bytes according to the priority of Table 4. When UNUSEDEN is set to logic 0, no
pattern is inserted.
UNUSEDV:
The unused value (UNUSEDV) bit controls the value inserted in the unused bytes. When
UNUSEDV is set to logic 1, an all one pattern is inserted in the unused bytes if enable via the
UNUSEDEN register bit. When UNUSEDV is set to logic 0, an all zero pattern is inserted in
the unused bytes if enable via the UNUSEDEN register bit.
