Any abnormal condition detected either:
- By these 3745 error detectors, or
- In the network
is signalled to the MOSS. Then, the MOSS:
Builds a BER and stores it on the disk for future use
Depending on the severity of the event, builds an ALARM message for the
3745 console(s)
Depending on the severity of the event, sends relevant information to the host
through NCP or PEP which, in turn, builds:
– An ALERT message for the NetView console, or
– An INOP message for the VTAM console, if NetView is not installed, along
with a logging record (Logrec) for the VTAM log file.
Errors detected in the integrated DCE can be handled as:
1. An error of a controller component
2. A network error.
A failure of the integrated DCE is also notified by an indicator on the LIC 5 or 6.
The local operator can then investigate the source of failure using the 5869
Portable Keypad Display. The automatic fault isolation procedure, triggered by
pressing the
Diag key, helps identify the faulty element, for example:
The local DTE or DCE
The line
The remote DTE or DCE.
