Installation, SPM, Maintenance, and Troubleshooting Supplement
When you select this test from the maintenance screen, the system sends a
request to the telephone at that extension (station), asking for the telephone’s
classmark. You can request the Station Responding Test locally or remotely.
Use the following sequence to run a Station Responding Test:
Menu: Maintenance
→Port→Type station no.→Enter→Test
The system responds with one of four results:
■ Pass—An identifiable classmark was received. This screen also indicates
the name of the device that returns the classmark (“Profile”).
■ No Response—No classmark was received. (Tip/ring devices respond this
way.)
■ Invalid Response—A classmark was received, but the system cannot
identify it.
■ Intermittent Response—A classmark was not consistently received.
Touch-Tone Receiver Test 9
The Touch-Tone Receiver Test runs as an audit on the system. It is not a
demand test but runs continuously in the background as a maintenance check.
This test checks every touch-tone receiver (TTR) in the system modules,
including those in the MERLIN Messaging System.
If a TTR fails the test, a permanent error is logged and the TTR becomes
maintenance busy. If 50% or more TTRs become maintenance busy at the
same time, and another permanent error is logged. (See “Error Codes” on page
9-10 for the new error codes.) The Touch-Tone Receiver Test itself does not
maintenance busy out 50% or more TTRs.
The Station Responding Test does not work for tip/ring devices
because tip/ring devices do not have classmarks.
