Performance Monitoring threshold levels for 15-minute

Protection Configuration Menu
Figure 16 represents the OC-3 MUX Protection
Configuration menu where Manual Switches and
Switch INHIBITS are set. A manual switch will not
override a Switch Inhibit. Descriptions of the menu
options are explained in the following subsections.
MUX Operational Status
The MUX Operational Status field indicates whether
the module is the Active controller of the clock source
copy switching (Online) or in Standby mode (Offline).
MUX APS Lockout Status
THe MUX APS Lockout Status indicates whether the
clock controller is allowed to switch to the protection
(ALLOWED) or are prohibited from switching to
protection (INHIBIT). MUX APS Lockout overwrites
DS3 APS Lockout.
MUX APS Switch
The MUX APS Switch option is used to manually
switch the DS3 traffic and the Clock Controller. When
traffic is split, all traffic will follow the Clock
Controller. When switching the Clock Controller, the
MUX also attempts to force the Access cards to switch
to receive the DS1 traffic from the Online MUX.
