Esa Ram Diagnostics; Escalation To Manual Maintenance; Loading Esa Static Translations Data - Nortel DMS-100 Series Maintenance Manual

ESA RAM diagnostics

The ESA processor is provided with a RAM diagnostic test. Operating
company personnel can use the TST command to implement this test. The
system can also implement this test during an RTS. The ESA RAM
diagnostic test consists of the following tests:

Escalation to manual maintenance

Manual maintenance can be required for certain testing conditions. The
following paragraph describes these conditions.

Loading ESA static translations data

This section describes how to manually load the ESA processor with static
translations data. Static translations data are part of DMS CC translation
data that the system downloads to the ESA processor.
The steps to manually download static data are:
1 Display the ESA MAP level for the desired RLCM.
2 Make sure the ESA processor is InSv or ISTb
3 Type:
4 Press: ENTER
If this process fails, the ESA processor becomes SysB.
a message test

— 6X75 status to ESA processor
— ESA processor to 6X75 control
— A-bus interface to ESA processor and memory
— frame interrupt generator
— clock synchronization hardware
— tone generator
— ESA messaging hardware
the 6X75 card test, which includes the following:
— status and control test
— RAM test
