Nevada connectivity & audio issues >>UPDATED
Last updated on October 29, 2010 by The C.A.R.L.A. Team | This article is Archived | Permalink
>> UPDATE << The Nevada ring is back on normal mode. The audio still has occasional issues and there are dead keys sometimes originating from the Nevada Hub (CARLA 18). we are still having issues with audio and signalling on the new IP circuit.
Recently we had to change the circuit design that feeds the Nevada ring (CARLA 18, 21, 22, 23, 24) from the rest of the network to an IP based connection.
This created an issue with the tx & rx audio quality on that connection. It basically sounds like a Nextel or cell phone going "digital" at times or just choppy. This problem needs further troubleshooting to remedy the issue.
More recently (Monday) there was a power outage at CARLA 5's site which also houses phone and data equipment and acts as our data hub, of which some circuits interface with the RF network at the site. Some of the digital cross connect equipment experienced a brownout and lost all the configuration files. This was ugly. Parts were replaced and the slow process of manually configuring all the ports and cross connect information from scratch started. They are not completely done and as a result we have lost the circuit feeding the Nevada ring temporarily.
In the interim we have cut over to the RF back-up path that connects CARLA 18 to the Vaca Hub via CARLA 8 as the hop point. The only issue with this is the added delay for another site in the path. An extra 1/2 to 1 second should be added as a beginning pause so traffic to & from Nevada doesn't get chopped off in the beginning of a sentence.
Once the permanent circuit to Nevada is re-established we will probably revert to that as long as the audio issue doesn't become intolerable. Hopefully that will happen this week.
We'll send updates as needed.
