Avaya 03-300430 사용자 설명서

This test is destructive.
The One-Way Span test allows 1-way span testing to and from remote test equipment or 
another Avaya communications system. This tests all circuitry and facilities from the local UDS1 
board to the remote test equipment or other Avaya communications system.
The test is destructive and can only be initiated with the test ds1-loop location 
one-way-span-test-begin command.
Each trunk or port on the UDS1 Interface circuit pack must be busied out using busyout 
board location before running the One-Way Span test.
The One-Way Span test has the UDS1 Interface circuit pack transmit a framed 3-in-24 test 
pattern and attempt to receive and verify the pattern. If the UDS1-BD board receives a framed 
3-in-24 test pattern sent from another Avaya communications system or test equipment at the 
far end of the DS1, it begins counting bit errors within the received pattern.

Note:

: If the One-Way Span test is run between a UDS1 Interface circuit pack and 

an MM710 DS1 Interface Media Module on a G700 Media Gateway, the test will 
fail because the MM710 does not frame-align its test pattern.

The status of the One-Way Span test is available in the hardware error log via Error Type 3902. 
Several distinct Aux values give the user information of the status of the test.
The list measurements ds1 summary command shows the length of time the test has 

been running (Test Duration field) and number of bit errors detected (Loopback/Span Test 
Bit-Error Count field). If the test pattern is being sent cleanly over the span from the far end, 

the number of bit errors should be very low. The Test Duration field will show 0 until the test 
pattern is received from the far-end. Upon receiving the test pattern, the board will begin 
calculating the test duration and number of bit errors. The command will also display the 
Loopback/Span test executing (Test field), the type of pattern generated for the Loopback/Span 
test (Pattern field), and whether the pattern (i.e., 3-in-24 Pattern) is synchronized 
(Synchronized field).
To terminate the test, enter test ds1-loop location end-loopback/span-test or 
release board location.   Using release board restores each trunk or port on the 

UDS1 Interface circuit pack to the in-service state.
