Phenomenon Descr
When I was implementing Broadband Service then I found the
iption:
repeated online and offline of ADSL port.
Before implementing this service i didn't check the
SNR Margin at the port. I found same problem for
many eqipment. And finally I checked the line condition
at the port. At some ports the supported Upstream Channel
SNR Margin was 16.5 dB and downstream Channel SNR Margin was 23 dB
but configured Upstream Channel SNR Margin is 31 dB and
downstream Channel SNR Margin is 46 dB (As per Configuration).
Due to this mismatch the problem was arised.
This SNR Margin check was applicable for all versions.
Alarm Informatio
Null
n:
Cause Analysis: The problem was arised due to faulty physical line.
The available physical line didn't support the
required SNR Margin for the Line Profile configured.
Handling Proces
To solve this problem i changed the physical line to
s:
another line and check the line conditions. The SNR Margin
of new physical line were matched with our requirements.
To check the SNR margin i use this command
"display line operation port port_no."
Suggestions and
This will be very useful when we are implementing any
Summary:
service on any port. Before providing any service to a
customer ( on any particular port ), we should check the
SNR Margin for that particular physical line.
By doing this we can imlement the service according
to the standards.
