This object indicates which working section is the APS
primary section. In G.783 AnnexB, the K1/K2 Bytes are
received on the secondary Section. All the Switch
Requests are for a switch from the primary section to
the secondary section. The object csApsActiveline will
indicate which section is currently carrying the
traffic. Once the switch request clears normally,
traffic is maintained on the section to which it was
switched by making that section the primary section.
Possible values:
workingSection1(1): Working Section 1 is Primary Section
workingSection2(2): Working Section 2 is Primary Section
none(3) : none.
