My customer is your CBS customer, and they have issues...

**Edited by Moderator**

I am a tech with a local low voltage company and my customer is having intermittent issues.

The service address is as follows:

X X X

X X X X

X X X

The modem RF levels are very good :

Frequency	801000000 Hz
Signal To Noise Ratio	43.1 dB
Power Level	8.7 dBmV The Downstream Power Level reading is a snapshot taken at the time this page was requested. Please Reload/Refresh this Page for a new reading

Upstream	Value
Channel ID	3
Frequency	24800000 Hz
Power	41.3 dBmV

The issue is with the HSI service regularly dropping out and the log file is as follows each time there is an issue. This is from yesterday. Whenever the issue occurs the cs experiences connectivity issues and severe lag. They have had several tech appts and since it is an intermittent issue, they are never able/interested to diagnose and repair the issue beyond the local level.
