Objective Line Evaluation function used to measure the potential capacity of Single/Multiple ADSL lines.


Prerequisites The N2510 is in the normal state.

You have logged in to the N2510 and have the rights to manage the device.

Procedure 1. Choose one single port and start the ”Line Evaluation” function;

2. Input with one group ports, these ports can be some ports of one DSLAM or some ports under different DSLAM, and check the “Line Evaluation” function.

Monitor the specific time range for 1 single port.

e. The system can support output the result for the whole network, one province,

several DSLAM, one DSLAM or 1 port.

Note:

a. The report is output by daily, weekly, monthly.

T01-0602 SELT test for Single/Multiple lines

Objective SELT test function used to measure the line quality of Single/Multiple ADSL lines.




The DSLAM software should support SELT function and better the Modem is not connect with DSLAM, generally the SELT is used before the service deployment.

Note:

For the MA5600 IP DSLAM, the current popular ADSL2+ card is H569ADEE,



Page 18 of 21


and the software version should be newer than 327, otherwise this ADSL2+ Service card does not support SELT. Check card version:

#display version frame/slot

Procedure 1. Choose one single port of the ADSL2+ card under-test and start the ”SELT” function and record the time.

2. Test 30 ports of the ADSL2+ card under-test at one time, because every DSLAM support 1 SELT session at the same time, so we should choose 30 different DSLAMs.

Expected result The general “SELT” result as following: The “SELT” function’s parameters are displayed successfully:

a. Brief information are expected to display as:

- Customer ID - CPE Status

- Attainable Rate US (kbit/s) - Port

- Attainable Rate DS (kbit/s) - Test Time

- Line Length (m) - Modem Status

b. Detailed information are expected to display as:

- Inband Noise

- DMT Margin vs.Rate (US)

- DMT Margin vs.Rate (DS)
