* A 22-type OLIU in a function unit is in “linear” (unprotected or 1+1 line protected), not a ring configuration.
† This table refers to only “low-speed” STS-1 interfaces.
‡
This entry represents the hairpin local drop cross-connection between a channel on an OC-1 ring terminating
on a pair of 26G2-U OLIUs and a DS1 port in the low-speed group associated with the 26G2-U OLIUs. The
MXRVO functionality on the 26G2-U OLIUs is used. Note that it is NOT possible to connect between a channe
on an OC-1 ring terminating on a pair of 26G2-U OLIUs and a 26G2-U/DS1 combination in a different function
unit.
§ MXRVO functionality within the 26G2-U OLIU is NOT used. Rather, a separate pair of MXRVOs in a different
FN group are used.
¶ Cross-connections from one OC-1 ring to a different OC-1 ring in a different function unit.
** One of the pair of function unit slots will be empty.
†† Cross-connections from one OC-1 ring to a different OC-1 ring in the same function unit.
‡‡ The mixing of 0x1, Pass-Through, and local Add/Drop cross-connects is supported beginning with R13.0.
§§ The mixing of 0x1, Pass-Through, and local Add/Drop cross-connects is supported beginning with R11.0.
