ZyXel C1100z "Timeout while collecting signal attn data"
« on: April 07, 2017, 02:04:11 AM »

Hi,

I recently got DSLStats functional with the C1100z by using the C1000 Zyxel profile. Everything except 'signal attenuation' is functional. This is the error popping up on the event log...

Code: [Select]
06 Apr 2017 19:39:50 Timeout while collecting signal attn data
06 Apr 2017 19:39:50 Telnet timeout
06 Apr 2017 19:40:20 Timeout while collecting signal attn data
06 Apr 2017 19:40:20 Telnet timeout
06 Apr 2017 19:40:50 Timeout while collecting signal attn data
06 Apr 2017 19:40:50 Telnet timeout
06 Apr 2017 19:41:20 Timeout while collecting signal attn data
06 Apr 2017 19:41:20 Telnet timeout
06 Apr 2017 19:41:50 Timeout while collecting signal attn data
06 Apr 2017 19:41:50 Telnet timeout
06 Apr 2017 19:42:20 Timeout while collecting signal attn data
06 Apr 2017 19:42:20 Telnet timeout
06 Apr 2017 19:42:50 Timeout while collecting signal attn data
06 Apr 2017 19:42:50 Telnet timeout
06 Apr 2017 19:43:20 Timeout while collecting signal attn data
06 Apr 2017 19:43:20 Telnet timeout

The line is an ADSL2+ Annex A line.

This is the stats tab...

Here's the --stats portion from the modem on telnet...

Possible that the C1100z does not support this additional reporting mode?

Am on firmware version CZW002-4.12.009.0.

Looks like it to me.
In DslStats, under "configuration", "items to monitor" uncheck "signal attenuation in stats".

I would say that j0hn is right. A separate command is used to collect the signal attenuation values, and the timeout occurs when it fails to collect the expected output within the timeout period.
