- USING CAT5 AND ANALOG PHONES FOR VOIP SYSTEM CODE
- USING CAT5 AND ANALOG PHONES FOR VOIP SYSTEM SERIES
Then there was the time in a Network Plus class where the instructor stated the color code "did not really matter as long as it is the same on both ends.", but that is a tale for another day. He also paid more consideration to my opinions on the phone system and cabling in general not to mention the bill for my troubleshooting. I am not sure what the implied threat was but I do know that as of that first Monday morning after the rework, ALL the message waiting indicators worked flawlessly. So, in a huff, he told me he was going to redo all the cabling to 568B and that "it had better work". I would no longer troubleshoot until the cabling was corrected as I had already eliminated all other causes that I could think of. I eventually asked him to stop calling me on this issue. If anything, he became more upset because this would mean reterminating both ends of the cables. I further explained this was engineered for noise rejection and to offer the maximum bandwidth capability, particularly at the greater distances that the specification called for. I removed the jacket from the cable and showed him how each pair had a different twist rate. It would certainly fail a certification attempt. I replied that while that would be true in the case of continuity, the cable could not be considered CAT5E because the standard was not followed. The Patton 4118/JS/EUI would convert SIP to analog and connect to FXS ports (ports to which an analog phone or.
USING CAT5 AND ANALOG PHONES FOR VOIP SYSTEM SERIES
For your application, we recommend that you consider Pattons 411x series devices. But gateways work in both directions - POTS to VoIP, and VoIP to POTS. As long as Side A and Side B were the same, the cable would work. For VX, gateways can take a POTS line and convert it to SIP for the VX to use. The IT person became most upset at this suggestion and insisted that color codes were not important. Either way, there is no additional cabling for power. For analog systems, use RG59 Siamese cable to combine the video and power cables into one jacket. I commented that these phones, which happened to be on the longer runs, were possibly not working properly because the standard was not adhered to. For IP networks, built in POE adapters make sending the power through the existing ethernet cable easy.
The IT person had followed their own color code instead of 568A or 568B. One interesting trouble ticket I had was a case where a handful of IP phones would not show the Message Waiting Indicator when a message was left. Especially if not trying to utilize any streaming or other bandwidth intensive apps like VoIP or video. I am sure we all have seen cases where cables much longer than this will appear to work OK.
The 100 meter distance is just a specification that a cable cannot exceed this distance and be considered a CAT5 cable.
