SYS-LINK (System Links)

MO's Name (in

System links are packet links that originate at the Packet Interface board and

traverse various hardware components to specific endpoints. The hardware

components involved on the forward and reverse routes can be different,

depending upon the configuration and switch administration. Various types of

links are defined by their endpoints:

Expansion Archangel Link terminating at an Expansion Interface board. This

link carries CCMS messages.

Indirect Neighbor Link terminating at a Switch Node Interface board

PNC ATM Control Link terminating at a PNC ATM-EI board. This link carries

ATM signaling commands from CaPro to the remote TN2238 (ATM-EI)

ISDN-PRI D-Channel Link terminating at a Universal DS1 board

Remote Socket Control Link terminating at a C-LAN board

Remote Socket Link terminating at a C-LAN board

Recording System Link Events

The system links MO records every error encountered on the links. Most of these

events are not extraordinary unless they occur with an alarming frequency. The

events are logged as they occur, leaving a "trail" to help analyze abnormal

behavior exhibited by the endpoints attached to the links or the links themselves.

When a link goes down, an alarm is raised immediately. For EAL, INL, and PACL

link types a MINOR alarm is raised; for every other link type a WARNING alarm is

raised. Other alarming conditions that do not cause the link to go down get a

WARNING alarm, regardless of the link type.
