m. The circuit pack’s message buffer is full. This may be caused by having
many display phones with heavy traffic connected to the circuit pack. No
action is necessary.
n. Internal system error. No action is necessary.
o. There is a problem with the voice terminal EEPROM. When the voice
terminal is repaired the alarm will be resolved with the passing of time.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. By clearing error codes associated with the Voice and
Control Channel Local Loop Around Test, for example, you may also clear errors
generated from other tests in the testing sequence.
Digital Terminal Remote Loop Around Test
(#1201)
This test checks the integrity of the connection between the SPE and the attached
Digital Terminal and the ability of the terminal and the associated port to send and
receive data.
A request is presented to the terminal to go into loop back mode. Then data is
sent to the terminal and when received back, checked for consistency. This test is
run as a part of the craft command “test long” procedure. It is not included in any
error recovery strategy and generates no Error Log entries or alarms. To begin the
test, Maintenance will ask Call Processing to make the associated end point and
port “Maintenance Busy”. This test will succeed if the endpoint is “idle”. If the
reserve request fails then the test will abort. If the request succeeds then the SPE
sends a message to loop around both information channels for the digital terminal.
First the primary information (voice, Information Channel 1 or I1) channel loop
back test is run. The test is performed by sending a digital count from the
Table 10-210.
