Ok, I now configured the equipment with the following settings: E1T1 Interface IO-1/2 : - adminon status Down alias timeslots(0-31) lineType E1CrcMf cfa true idleCode 0x7e lineCode HDB3 restoreTime 721E1 lineLen Not supported for E1 sensitivity Not supported for E1 gain Not supported for E1 fdl N/A dsucsu Not supported for E1 ifClkTypeCard ifClkSrc N/A loopStatus None hasCesSignaling false RxLineLoop off - and zaptel with CCS/HDB3/CRC4. But the equipment still reports the LOF alarm and zaptel a yellow alarm :( One thing, the equipment is an E1/IP tunneling system. I'm not sure about the hasCesSignaling option, which is described as "E1/T1 has a Cesoip service that carry its signaling". When set to true, zaptel gets a red alarm instead.

Or is it "E1Mf"? The "E1" setting aboe is for an E1 with *no* signalling channel, a very uncommon configuration. Use E1CrcMf and enable CRC on the asterisk box. E1:s are almost exclusivly run in multiframe mode and with a dedicated signalling channel.

So the problem only appears when the TE410P tries to speak to the other equipment. On the latter, I can choose the linetype to be one of the following: E1Unframed - 2 Mbit/sec unframed signal E1 - 2 Mbit/sec framed PCM31 signal E1Crc- 2 Mbit/sec framed PCM31 signal with CRC E1Mf - 2 Mbit/sec framed PCM30 multiframed signal E1CrcMf - 2 Mbit/sec framed PCM30 multiframed signal with CRC Since I want to use PRI signaling I have configured zaptel in CCS mode. So I think the right choice on the other equipment would be "E1", am I right? Or is it "E1Mf"?

Re: [Asterisk-Users] Problem connecting a TE410P to an E1/IP equipment
To test the TE410P itself, you can construct a simple cross-over cable by hacking up a short CAT-5 cable as you describe: 1 - 4 2 - 5 4 - 1 5 - 2 Note that a CAT5 crossover cable will not work. Once you've done this, set up two spans on your TE410P as you've done it, except that one of them should be CPE and the other one NET in zapata.conf. Now calls originated on any of the 30 channels on one span will appear as incoming on the other one. I don't think the clock source as set in zaptel makes any difference for these purposes, as it's specifying the clock source for functions like meet-me, not the framing clock which is derived from the E1 signal itself. One last thing is to check the jumpers on the card itself to make sure they are set for E1. (doesn't look like this is the problem tho) And, finally, actually shut the system all the way down, including power, and reboot to make sure new settings are loaded into the TE410. I think this is a design shortcoming in the card that it's possible for it not to clear it's settings even on a restart (without power down) With the setup above, you should get green lights on the connected spans, and should be able to send calls from one to the other. By the way, to initiate outbound calls use the .call file facility (see the Wiki) Good luck! Scott Stingel President Emerging Voice Technology, Inc.

Asterisk can hear the other box, but the other box does not hear Asterisk. Ususally you would expect a red alarm (Loss of Signal) and not a LOF in that case. The cable may be good enough to receive the signal, but with enough errors to prevent the framing to be detected. Unusual, but possible. Of course, it could just be a configuration mismatch. Try placing loops at various places and see if the machines can see themselves after a round trip.

Yellow alarm means that the "Alarm Indication" bit is set in the received syncronization frame from the far end equipment. As far as I know (and can tell from Cisco etc) the AI is most often set on incoming red alarm, i.e. loss of signal. > LOF usually generates "red alarm" in my experience if left uncorrected :-) LOF would generate a local red alarm and a yellow alarm at the other end, if that path is working. What the original poster is seeing could be as simple as one pair being bad. I think a slightly broken rx pair from the remote equipment to his Asterisk box would create this pattern of alarm. Of course, it could be a broken E1 card as well at either end. I'd try placing a loopback plug at various places, facing either way, along the path between the two pieces of equipment.

Yes, "Down" here means the span is down, Asterisk is not able to communicate over the D-channel to the other end to bring the span up.

[Asterisk-Users] Problem connecting a TE410P to an E1/IP equipment
Hi, I'm trying to connect a PC with a TE410P to an E1/IP equipment. Unfortunately I keep getting a yellow alarm from zaptel (in zttool) and a Loss of Framing alarm on the remote equipment. The E1/IP is connected on the other side to a PRI interface on a GSM MSC. I have configured the span as: span=1,1,0,ccs,hdb3 (also tried span=1,0,0,ccs,hdb3) and the channels as: bchan=1-15,17-31 dchan=16 The LED on the port is green. I tried to load both the se and us tonezones (I'm in Sweden). Is there a way I can know why the yellow alarm was triggered? And do you have ideas why the other equipment reports a LOF alarm?
