Span Filter Config

Type

EXS API and SwitchKit API message

Description

This message is used to configure the detection of a Carrier Group Alarm (CGA), such as an AIS (Alarm Indication Signal) or LOF (Loss of Frame).

The "CGA Detected" validation timer determines how long a CGA alarm must be detected before the Excel platform informs the host with an Alarm message. The default is 2.5 seconds. The host will also receive a DS0 Status Change message of "Out Of Service" for the channels on the span.

The "CGA Cleared" validation timer is initiated after a CGA alarm has been detected and then clears. It determines how long the Excel platform must go without detecting a CGA alarm before informing the host with an Alarm Cleared message. The default is 12 seconds. The host will also receive a DS0 Status Change message of "In Service" for the channels on the span.
