Warning Messages

While problems that generate warning messages do not prevent CMS from
managing calls, they do adversely affect call management in various ways.
This section describes those effects and gives instructions for correcting the
problems.
WARNING--CU 2 Faulty or Disconnected.
Effect on Call Management: CMS manages calls somewhat more slowly
without CU2. You may notice an increase in abandoned calls during periods
of heavy incoming call traffic until you correct this problem.
Contact the MERLIN LEGEND system manager before attempting these
corrective actions.
Possible Cause
A cable connection
between the CU2 jack on
the CMS card and the
control unit is loose.
Either the cable or the jack
assigned to CU2 on the
control unit is faulty.
Corrective Action
1. Unplug the CU1 cable from the CMS PC
and plug it to the CMS supervisor tele-
phone. If the phone does not work, go to
step 2.
2. Make sure the connections between the
CU2 jack on the CMS PC and the control
unit are secure.
Test at the control unit with a console in
3.
the jack for CU2. If it works there but not
at the PC, the problem may be wiring.
When you can interrupt call management for a
few minutes,
1. Reverse the cables plugged into the CU1
