CO trunks GRD -start...what does RVSD mean?

[dweiss]

This is a snapshot of seven 2-way CO trunks in an Option 11C, REL 25.4. I manage Can someone tell me what the RVSD in parenthesis stands for? I have five users in this office, and they are complaining that they occasionally get a busy signal when they try dialing out (both long-distance and local calls), and I am trying to trouble shoot the issue. The route for these trunks is RO 5, and SRCH is LIN, and ICOG is IAO. So, what is RVSD?, and how can I ensure that outbound calls are looking at the group of seven CO lines correctly. BTW...inbound calls to these trunks (hunting set up on the carrier end) is working beautifully. I am thinking I may have a glare situation, but before I start chasing leads....thoughts?

REQ: stat 5
00 = UNIT 00 = IDLE (TRK)(CO GRD )
01 = UNIT 01 = IDLE (TRK)(CO GRD )
02 = UNIT 02 = BUSY (TRK)(CO GRD )
03 = UNIT 03 = IDLE (RVSD) (TRK)(CO GRD )
04 = UNIT 04 = IDLE (RVSD) (TRK)(CO GRD )
05 = UNIT 05 = BUSY (TRK)(CO GRD )
06 = UNIT 06 = BUSY (TRK)(CO GRD )

It means the tip and ring of the trunk is reversed. The polarity needs to be correct for ground start trunks to work.

I would also do a trace on the one's that say busy and make sure there are real calls up on them. But the one's that say RVSD are not functioning and wont work until the polarity issue is resolved.

KCF...that is what I suspected...thanks! Owe you one. I am a remote admin, so I have to get a tech out to change the polarity.

That error can be misleading sometimes. Most of the times the trunk is reversed, on occasion the trunk is just dead form the telco. Regardless, dispatch is needed.

Disable and enable the trunks then if you can have someone access that trunk you'll see if it was a hick up or if they really are reversed. I've had them go reversed in the past just becuase the CO was doing some maintenance down the line somewhere.

Have the tech take a card with him too of it's a long drive. I have seen lightning take these cards out on occasion. If you do try the disable/enable then on COT trunks you can actually make a call on them through your remote access in LD 36.

Command is

call tn then the number to call

So you would do

call 4 4 then the number you want it to call back to

Hawk...I see the errors in the call logs as well (TRK xxxx...dont remember the exact code right now), since the system's install a couple of weeks ago. I mentioned them to the installing tech, and he waived off my concerns. So, now I am having him go back out and flip the pairs at one end on each of those two trunks...no if, and's, or but's. I believe that it was a polarity issue from the git-go, and if not, a glare issue. I will keep your tip in mind, and give it a go if flipping the pairs at one end doesn't correct it. Thanks!
