I for one think it is a great idea to buy a book with hard earned money and wait a few days to a week just to get an answer to a question that is freely available on the internet immediately. Hard pressed to think of anything in the "book" that is not on with wiki with more up to date and useful information. -----Original Message----- From: Alexander Lopez

The "telco guys" probably did something non-industry standard and reversed send and receive in the jack that they plugged the CAT5 into. Sure it works, sure it is easier, sure it is not the correct way of doing things.

I have used cross-connect wire from the spool to make T1 crossover cables with RJ45 ends. All that matters is that pin one goes to four and two goes to five on both ends. ________________________________ From: asterisk-users-bounces@lists.digium.com on behalf of Andrew Sent: Sat 4/22/2006 2:51 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: Pinouts for T1/E1

Can't anyone stop self-promotion and tell the poor guy what he needs. A T1/E1 X-over cable using an RJ-45 (8-cond.) is pinned out as follows: 1 - 4 2 - 5 3 - NU 4 - 1 5 - 2 6 - NU 7 - NU 8 - NU NU = Not Used I have not in my experience seen any problems with using a Good Quality Cat5 vs. Cat 3 (telco standard) cable for X-connects. YMMV, but you should be fine. As far as the shielding

My telco used cat5 as well for the demarc to CPE. It's also with noting that many channel banks, such as my Atlas, and zapata.conf itself also have parameters to allow you to tune the gains to compensate for cable signal loss. I've never had to touch them, and my CPE is about 300 feet from the PRI demarc (with an ordinary Cat5 cable connecting them)

I was once told by a lineman that the cables they use didn't have that many twists in them because it wasn't needed, and that the extra twists would effectively use more cable and thus cost and weigh more than triple what they do now. He told me that with the number of twists in the Cat 5 cable it would cancel out any interference, but he also stated that the effective length was

At Sangoma we do quite a lot of back-to back T1 and E1 connections. T1 is not a very fussy connection, as the baud rate is only about 750 kbps. In our experience, for error free communications you can use the following rules of thumb: Up to 50 ft: Flat patch cable Up to 500 ft: Ordinary twisted telephone cable Cat 5 may be overkill unless you are going hundreds of feet.

I'm connecting a T1 PCI card to a Nortel Option 61 switch T1 card. My Sangoma A102D shipped with 2 T1 cables - which I assume are straight through. Do I need to make crossover cables for this scenario? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

Hi, Digium's E400P has RJ45 conector and my E1 link has BNC concetor. Could someone tell me the cable pinouts to make this conection? thanks Eduardo

Say I had a crossover cable that connected a Mitel SX200 to a TE110P and the pinout was done as such: 1 - 4 2 - 5 5 - 1 4 - 2 (the 5 and 4 are transposed on the left side) Instead of the proper way of: 1 - 4 2 - 5 4 - 1 5 - 2 What would the results be? We have had the former as our cabling for a few months and the connection has been fine. Slip errors here and there. But we have had major

i'm getting a tick every second or so on all my calls. All channels are zap channels. Does anyone know how to fix this? Thanks!

Hello all, I have obtained a Compaq T700 H UPS sans-cable. My research indicates it would've come with a HP #201092-001 cable, and from previous posts on this list, it speaks upscode2, possibly being a rebadged Eaton unit. Any suggestions for cable pinouts I can try? Regards, Mathew McBride

I need to dial an extension that tells me what extension I'm dialing from. I'm running a bunch of analog phones off a channel bank to * over a T1. I have the following in extensions.conf. exten => 98,1,SayDigits(${EXTEN}) This says the digits the caller enters on the keypad, not the extension they are calling from. Thanks Guys!!!!!!!! Paul Paul Mahler pmahler@signate.com

I would like to be able to detect when someone dials *. What I'd like to be able to do is exten => *,1,Answer and catch it when the caller pressed the * key. Thanks!

I am using a IPDialog siptone II. I can take incoming calls, but when I try and make an outgoing call I get a SIP 407 error. Can some kind soul explain to me what I am doing wrong? Here's what I found in the wiki: If a proxy does not accept the credentials sent with a request, it SHOULD return a 407 (Proxy Authentication Required). The response MUST include a Proxy-Authenticate header
