the power switch to the ON position
• if the power switch is set to the ON position, follow Procedure 3-1 to
troubleshoot the DSLAM for power up problem

Problem indication: No POTS service to the affected subscribers (VDSL/ADSLx
service is ok).

the problem, replace the DSLAM.
3 Check the condition of the POTS lines and connectors.

If this step results in POTS service to the affected subscribers but there is still
no VDSL/ADSLx service to them, follow Procedure 3-3 to troubleshoot VDSL/
ADSLx service problems.
If this step results in ADSL service to the affected subscribers but there is still
no POTS service to them, follow Procedure 3-4 to troubleshoot POTS service
