Good source for jack pinouts 2

[mrgauth]

I am not a phone guy or anything and looking for a place to see what the pinouts should be for a rj11 jacks if I want to wire a simple loopstart line or DID. I know they only involve two wires, but on which pins to they go on one of those rj11's.

I know you voice guys are laughing, but a web page that has all of this crap, and more, for us non voice savvy guys would be great to know.


Thanks way in advance.

will get you basic pinouts.

A DID is not wired differently than any other connection, that's a function of you phone system and provider.

Yes, but a DID line is polarity sensitive. Because they are normally Wink Start.

An analogue DID trunk is polarity sensitive because of the way the circuit functions. Without the polarity function there would be NO wink, delay-dial or answer supervision. There are three types of start signals: Wink, Delay-dial, and Immediate.

An RJ specification is not a piece of hardware. It is a wiring arrangement. An RJ11 is a wiring arrangement for Tip&Ring analogue dialtone on a 6 position modular jack, using pins 3&4 for the line. Modular plugs are NOT "RJ" anything!! Data and Category anything has nothing to do with "RJ" either!!

HOPE THIS HELPS!

I'm going to ask a really stupid question here, but the answer could help me fix a major PITA I'm having...

On the buttset, red and black, which one is tip and which one is ring. I'm sure I could look it up, but then you guys wouldn't have anything to chuckle about.

As far as I understand it, I have a fractional T1 coming into a building I take care of the phone system in. it's hooked up to an AdTran 624 and broken out into an RJ21 that is provisioned for 12 standard trunks and 4 DID trunks. The vendor had a lot of trouble getting it up and running and I finally sorted it all out. It ran fine for a year and then there was an issue - somebody messed with stuff, and I need to make sure the polarity is still right (just because the white/blue is punched down on Tip on both the RJ and the trunk block does not mean it's not reversed coming out of the AdTran - that's how I fixed it the first time)... It would be nice to know when I kook the wires up and get the green light on the buttset which order I punch them down in!

 

[SYQUEST]

One simple rule for this is: RING is RIGHT, RIDGE, RED!

I learned this from an old phone guy back in the 1960s. The RIGHT binding post is RING, the RIDGE on drop wire is RING, and RED is RING!

At least that is one thing that has not changed!

Thank you. Have a star.
