The resources for a 12.2 kbps voice service channel are regarded as a "point". 
Other service channel resources can be converted into a multitude of points. 

 

The E1/T1 performance routine test shows the quality of the E1/T1 cable.  

This test has no negative effect on the services, and can be done by the MML 
command only.  

The E1/T1 cable has no physical damage but has error bit in transmission.  

Follow the steps below to perform an E1/T1 performance routine test:  

1) 

Execute the MML command of STR E1T1RTTST. 
An E1/T1 performance routine test is started. 

2)  Note down the ID for the task under test. 

 

z

 

When the E1/T1 routine test is started, the NodeB assigns an ID to each task and 
sends it to you. With this ID, you can query the task under test.  

z

 

If you lose the ID, execute the MML command of LST RTTST to get it. 

 

3)  Wait for a while longer than the test time set by the MML command of STR 

E1T1RTTST. Execute the MML command of STP RTTST to stop the test.  

Then the system displays the E1/T1 performance routine test result. 

You can tell the E1/T1 link status through E1/T1 performance routine test in real time. 
Any error in the test results indicates a line fault.
