mscApsWorkingLine 1.3.6.1.4.1.562.36.2.1.134.11.1.2

This attribute is a link to the Path component whose parent Sonet or Sdh component provides the Aps' working line. A value must be defined for this component. The working line must exist under the same Lp as the protection line and must link to a Path component under the same type of port component (Sonet or Sdh) as the protection line. Valid workingLine and protectionLine pairs must exist. For the 1pOC12SmLrAtm card, the workingLine must be lp/n sonet/0 path/ 0. For other APS compatible cards, the workingLine and protectionLine pairs must use port 0 with port 1 and port 2 with port 3. For example, if the workingLine is linked to a path on port 0, then the protectionLine must be linked to a path on port 1. Sonet APS is available on cards of type 2pOC3SmAtm2, 2pOC3MmAtm2, 4pOC3SmIrAtm, 4pOC3MmAtm, and 1pOC12SmLrAtm.
