ERR5306 Jumping from card to card

[30n30w]

Has anyone seen Err5306 be something other than a bad port on a card, or wet pairs? Is it possible that it’s one of the common cards? Conf/TDS or DTR? Guesses?

I’ve been dealing with an intermittent problem (not the 61c rel 4.5 grounding – it’s perfect according to the NTP’s) that seems to be randomly jumping from pair to pair on a 300 pair cable that feeds multiple buildings. Originally, it was mostly analog phones in one building. As I disable those ports, and in two cases jacked the analog message waiting line cards; the problem started up on other ports, and they are all over the switch – analog, digital, different shelves, etc… I have a splice that I suspect, but jumping from pair to pair kinda means there is induced voltage, and when one pair is disconnected it takes the next best path to ground? All the bond clamps on the underground are intact and verified as being good grounds.

I’ve got ports that are cross connected, (but no phone instrument at the other end) phantom dialing internal extensions, leaving static messages on voicemail boxes and in a couple of cases, dialing 911!
I’m scratching my head and chasing gremlins…. Any thoughts?

Does it seem to be consistant no matter which unit is active? That could be a tough animal to track down.....

As I disable port/pairs that are showing errors, I'm getting the same errors a random about of time later on port/pairs that have been working fine in the past; or even fine a few minutes before. I just don't get it....nasty little gremlins!

Is your feeder cable grounded and if so, is it grounded one end or both ends?

 

[30n30w]

There are 4 total splice points and the sheath is bonded correctly together at each - and at each point they bond to a ground rod within the vault. At each vault, takeoff cable bonds to the 100pr protector can which are all grounded to the telco frame in each building. I really don't think the grounding is at issue here - it all appears and tests (ohms jacket to jacket and jacket to ground rod, plus ground rod to nearest building ground) I think it's a bad splice on one of the takeoff cables in one building, but I've never seen things jump all over the main cable like this - I've got issues now in multiple buildings and the only common points are a major splice can (bone dry) within the switchroom and the switch itself for the majority of the pairs.

Not an expert on grounding by any means, but I thought they were only supposed to be grounded at one point, so you do not introduce ground loops, ie the ground in one location may not be the same as a ground in another so you get current flow.

You always ground and bond the cable sheath and ground the protectors at both ends. Also where ever there is a splice the sheath needs to be grounded and passed thru.

This is the error you are getting????

ERR5306 Digit dialed exceed maximum allowed. More than 10 digits received.
Action:
Severity: Minor. Critical to Monitor: No. SNMP trap: Yes

Regarding Grounding: There seems to be two schools of thought - ground one end only or ground everything; I have actually tried it both ways in this case, but it doesn't seem to make any difference to the problem I'm dealing with.

And Yes - this is the error: (small sample)


ERR5306 0000401F 00000C88

I know these two happen to be a couple of analog lines for a fire alarm panel; but they just started showing up after disabling a different analog phone.

There may be two schools of thought on grounding but there is only 1 right way to do it. Ever been in a C.O. and seen the grounding and bonding there? Then go the customer premise and see that it is grounded and bonded there also. The reason for that is if you lose ground on one end then you still have it on the other. It will also be grounded and bonded in each pedestal where there is a splice. Anyway, enough about that. It is not your problem and the error code it is throwing doesn't lead me to believe that it is even a cabling issue.

Because it crosses shelves, sides, and cards, it has to be something common - since it happens regardless of Core 0 or 1, that would leave CNI, Conf/TDS, and DTR correct?

Per Sig is a core card - it would change from side to side correct? (I haven't thought about these cards in a long time!....) Start troubleshooting at the core and work you way out....

 

[KCFLHRC]

Actually your per sigs are always active no matter what core you are running on. They aren't really a core card. Your core cards are CPU, Sys. Util and CNI in a 61. All other cards are active regardless of what CPU you are running on. It could be a per sig or a 3PE. I always start simple, start at the set and work your way back. You may have just cause thinking it is cabling,and it could be, the odd thing is the error code doesn't really support that theory. I would definitely remove the jumpers that don't have phones plugged in. Having a digital TN out there not knowing where it is terminating is never a good thing. Same goes for analog but I have seen digital ports take whole IPE shelves down.
