Hi Forum,

Facing issues with configuring TATA E1 line with Digium TE121p, on asterisk-1.2.26, zaptel-1.2.23 & libpri-1.4.5

As per TATA people here; termination is Pin 1&2 - Rx , Pin 4&5 - Tx. Have put a straight through cable to terminate on the card bracket in similar fashion i.e. Pin 1&2 - Rx , Pin 4&5 - Tx.

Here's my zaptel.conf and zapata.conf

[zaptel.conf]
span=1,1,0,ccs,hdb3
bchan=1-15,17-31
dchan=16

Errors received; while starting asterisk:

ERROR[4177]: chan_zap.c:10415 setup_zap: Signalling must be specified before any channels are.

Help required urgently.

Thanks in advance.

You may connect the cable in the following way

Tata TE121p
1 -------> 5
2 -------> 4
4 -------> 1
5 -------> 2

Also check with your provider if CRC is on, if so you will need to add crc to zaptel.conf

span=1,1,0,ccs,hdb3,crc4

Thanx for yoour prompt reply.

Did the changes, the errors went away but the output of "zap show status" has changed from OK to REC.

Attaching output of few, suppose they can be of help:

zap show status
Description Alarms IRQ bpviol CRC4
Wildcard TE121 Card 0 REC 53 0 0

zap show channels
Chan Extension Context Language MusicOnHold
pseudo default en default

Yes, have changed the connectors as per your suggestions.

Also, had a word with NOC people, they say they are receiving LOOP(heck i don't know what that means).

Also, when i try to dial through a soft phone, i receive the following:

Executing Dial("SIP/901-b700db30", "Zap/g1/12127773456|55|tTo") in new stack
Jul 20 14:39:05 NOTICE[4083]: app_dial.c:1076 dial_exec_full: Unable to create channel of type 'Zap' (cause 0 - Unknown)
== Everyone is busy/congested at this time (1:0/0/1)

The extensions conf has been done as per the guide.

Hi,

Still getting these errors:

If its creating a loop, put back your old cable, remove CRC from zaptel

did u install libpri

reinstall it in this order

libpri, zaptel, asterisk


regards

Diyanat

libpri-1.4.5

you seem to have install wrong version of libpri, install the correct version for asterisk 1.2

Hi Diyanat,

Thanks for your prompt replies, it helped me.
Now some strange messages are being displayed on asterisk console.
I'm pasting the output here:


Jul 21 01:19:45 WARNING[9442]: chan_zap.c:9151 pri_dchannel: PRI Error: We think we're the network, but they think they're the network, too.
Jul 21 01:19:46 WARNING[9442]: chan_zap.c:9151 pri_dchannel: PRI Error: We think we're the network, but they think they're the network, too.

Jul 21 01:19:48 WARNING[9442]: chan_zap.c:9151 pri_dchannel: PRI Error: We think we're the network, but they think they're the network, too.


When I issue the "zap show status" command, this is the output:
Description Alarms IRQ bpviol CRC4
Wildcard TE121 Card 0 OK 54 0 0


I tried to dial a number directly through softphone, this is the console output:
-- Executing Dial("SIP/901-b700ed90", "Zap/g1/12127773456|55|tTo") in new stack

did u change signaling to pri_net in your zapata.conf ? it needs to be pri_cpe

post your zapata.conf again


Diyanat

Thanks in advance

your zapata.conf looks ok, try rebooting your server and the PRI modem box and try making a call

as far as i know tata PRI needs a different cable then the straight one, try using the cable you made earlier

for more details check http://74.125.153.132/search?q=cache:sh ... +PRI+cable

check with your provider as to what message they see on their side

Hi,

Issue resolved. The problem was at provider's end only.

Appreciate the guidance and support.

Thanks.
