...n impact. > IIRC, standard Ethernet uses pairs 1&2 and 3&6. The color scheme on "568B" is 1&2 = white/orange pair, 3&6 = white/green pair Most Ethernet cables then have the white/blue pair on 4&5, and white/brown on 7&8. An RJ45 carrying a T1 is: 1 - RxA 2 - RxB 4 - TxA 5 - TxB Assuming that you'd want RxA and TxA in the same twisted pair (ditto for RxB and TxB) then a cable would look something like this at each end: 1&4 = white/orange pair 2&5 = white/blue pair I don't know if there's an industry standard for T1 cabling to have a ce...

...to work with it. By fiddling about, I've come up with the "almost working" configuration below. This works except that it takes about 4 seconds from when the console says the line is answered until it plays my prompt. Watching the card with zttool, all flags start at 0. Then RxA, RxB, TxA, TxB, TxC, TxD change to 1. Then, a split second later, TxA, TxB, TxC, and TxD change to 0. A couple of seconds later, TxA, TxB, TxC, TxD change to 1 and the call progresses. What does this mean? Can you identify the proper configuration from this "handshake?" Verbosity is at lea...

...got: Asterisk server hooked up to a digital T1 line (full 24-channel) via a Digium card. Verizon has turned on caller ID on the first line (I can guarantee it is on as I can hear the FSK tones on this line but not the others). Using zttool an ZapScan() I have determined the following: 1) The RxB/RxD bits toggle from 1 to 0 signaling a ring. 2) A short time later, via ZapScan() I can hear the FSK tone. 3) About the same time I hear the FSK tone I see the "Starting simple switch" line in the Asterisk console. 4) Next I see the second ring trigger in zttool and then Asterisk say...

...patch cable. Correct. I mixed up "pair 1" with "the pair of wires connected to pins 1 and 2." T1 uses "Pair 1" and "Pair 2," which was what I was trying to say and what you *did* say! :) > > An RJ45 carrying a T1 is: > > 1 - RxA > > 2 - RxB > > 4 - TxA > > 5 - TxB > If you are referring to A and B as the differential signal components then you're right about the wiring. In either case you're wrong with respect to the pairing. :-) Sorry, I am used to the way NEC documents their PBXs and this is what they call...

...ource: On or Off, seems not to make a difference Framing: ESF Line Code: B8ZS CSU: On or Off, seems not to make a difference Once I managed to get all three status lights on the channel bank green but the T100P was red. On the few cases the T100P gives a green status, zttool shows the RxB bits randomly flipping one and off. I have tried different T100P cards in different servers so that has been eliminated as a cause. I have made up several T1 loopback cables so I don't think it is a flaky cable. The remaining possibilities are: a) a bad channel bank (although it passes the...

Hi, It seems like my ATA is making a ringing noise... (as it used to), but now (After the upgrade from 1.0.7 to 1.2) asterisk also is either making the ringing, or passing the PRI ringing from the telco on to me. Any suggestions on how to fix this?
