Re: [Asterisk-Users] TE410P Errors under load
For anyone trying to make an E1/T1 crossover, here's a nice diagram from NMS that may help. The only pins that are needed in a short cable for testing are 1,2,4,5. Aren't those the only wires that need to be connected for _any length_ of cable since the others are non-connects on the jacks?

RE: [Asterisk-Users] TE410P Errors under load
For the benefit of others who may experience this (multiple frame rejections and PRI read errors under high IVR call volume- E1 circuits) I've discussed this with Mark at Digium, and he's called into my system. There may be a problem with PRI software frame buffering with a high volume of call setups. I will create a bug report so that this can be tracked. In the meantime, if possible I'd like to verify this problem on another system. If anyone has a TE410P and would like to try my load tester on their system, could you please contact me *off-list*, and I'll send you my call generation Perl script for you to try. You would need one E1 crossover cable: (This is simple to construct from a CAT5 Ethernet patch cable). I can make the problem occur with only 30 sending and receiving channels on the same system...

Might you be getting problems because you are using an Ethernet cable?

RE: [Asterisk-Users] TE410P Errors under load
Yes it is different, the E1 crossover cable pairs 1+2 with 4+5. What I meant was that you can make a crossover by cutting up a CAT5 cable and redoing two pair (I wan't clear) Cheers Scott Scott M.

A 568B Ethernet cable will be paired as follows: 1 ORG-WHT 2 ORG 3 BLU 4 GRN-WHT 5 GRN 6 BLU-WHT 7 BRN-WHT 8 BRN As you can see you still maintain twisted pair integrity for T1 applications (1-2, 4-5), as well as Ethernet (1-2, 3-6). The primary issue would be shielding as most Ethernet cables aren't shielded.

RE: [Asterisk-Users] TE410P Errors under load
Yes, that's true how the pairs are formed, and its also true that a (short) ethernet cable can normally be used as a straight through E1/T1 cable, since all wires are connected. We need an E1 crossover cable for the tests we're running, and so we have to make one, because an ethernet crossover cable will not work.

RE: [Asterisk-Users] TE410P Errors under load
One of the simplest ways to make a T-1 (E-1) crossover is to take a dual RJ-45 biscuit and do the crossover inside it. Label it as a crossover with a Sharpie. Then you can use two normal cables. I always had at least one of these in my kit when I was doing field work.

RE: [Asterisk-Users] TE410P ERRORS under load
Mark- The system is Tyan s2723, which includes an integrated graphics controller, and I've connected a monitor to this port. I don't start the X-windows software however, and I don't use this monitor. For starting my scripts, I connect using SSH via an Ethernet port, however everything operates in background mode, there is no output to any console while these tests are running - just log files. I do receive an occasional Double/missed interrupt message - but very few of these. Will report the results of testing your new driver code! Thanks Scott Scott M.
