Phone service is lost (IP

Phones display SYSTEM

BUSY when they go offhook),

and a MOSS alarm appears

in the CDE forms header.

A database from

another system with

different MOSS

options has been

installed in the

controller.

Enable the correct options to

restore phone service and clear

the MOSS alarm. See “Enabling

MOSS Options” on page 88..

DNIC set displays WAITING

FOR SYNC or WAITING

FOR COMM at 20 second

intervals.

The set is having

trouble communicat-

ing with the Periph-

eral Bay MCC.

The likely cause is

one of the following:

• Defective Digital

Line Card.

• Defective bay

controller card.

• Defective set.

• Loose or

improperly

installed wiring.

Check the wiring. If the problem

persists, replace the set. If the

problem affects multiple sets on

the same card, replace the card. If

the problem affects sets on

different cards, and other causes

can be ruled out, then replace the

bay control card.
