Description: An entry is created when an APS pair is configured. To create an entry, the following objects must be specified: csApsWorkingIndex, csApsProtectionIndex, csApsEnable, csApsArchMode. The protection line must not be active, i.e, ifAdminStatus must be 'down', while configuring APS. An entry is created by setting the value of 'csApsEnable' to csApsEnabled (2) and deleted by setting it to csApsDisabled (1). Once a line is configured as working line or protection line, it remains in that role until APS is disabled on that sonet line pair. It remains in the working/protection role even after the card is reset.
