asterisk users - Jun 2006 - FW: asterisk and nortel meredian option 11c

Hi 

 

 

I want to connect asterisk 1.0.9 ( kernel 2.6.8-2 debian )with TE110P
and Nortel meridian option 11c release 25.40 with NTBK50AA card which is


An E1 card. But the main problem is the first stage that no sync occurs
the * card never syncs with meridian card

 

 

 

I am using euroisdn, ccs , hdb3, crc4 , pri_net on asterisk

 

And I am assuming that meridian is using same as it is connected to
Nortel passport mvpe card which is an e1 isdn card and using the same
config as astresk but the card never see each other. On the contrary
when I connect the asterisk with the Nortel passport mvpe card it does
detect the mvpe card but the d chan flaps btwn up and down and the hell
of HDLC BAD FCS messages appears on the cli of * .

 

I have also tried yellow alarm on the span but not of any help .

 

 

Can any one tell me the config of meridian option 11c and asterisk and
what I am doing wrong.

 

 

thanks

Muhammad,

I have been struggling with M1 and * over an E1 for a while myself, but know
it's running fine.
Here's my d-channel config:

 ADAN     DCH 18
  CTYP MSDL
  CARD 08
  PORT 1
  DES  Asterisk1
  USR  PRI
  DCHL 8
  OTBF 32
  PARM RS422  DTE
  DRAT 64KC
  CLOK EXT
  IFC  EURO
  CNTY BEL
    PINX_CUST 0
    ISDN_MCNT 300
  CLID OPT1
  PROG NCHG
  CO_TYPE  STD
  SIDE USR
  CNEG 1
  RLS  ID  **
  RCAP COLP
  MBGA NO
  OVLR NO
  OVLS NO
  T310 120
  INC_T306 0
  OUT_T306 0
  T200 3
  T203 10
  N200 3
  N201 260
  K    7


It's a config where Asterisk is master and Meridian is slave in euroisdn.
The zapata.conf that goes with that:
#-----------------------------------------------
[trunkgroups]
[channels]
context=incoming-pra
busydetect=no
usecallerid=yes
cidsignalling=v23
usecallingpres=yes
callerid=asreceived
switchtype=euroisdn
signalling=pri_net

group=1
channel=1-15,17-31
 #-----------------------------------------------
Make sure your [trunkgroups] section is empty!
I lost a lot of time on that one myself!

Zaptel.conf:
#-----------------------------------------------
span=1,0,0,ccs,hdb3
bchan=1-15,17-31
dchan=16
loadzone=be
defaultzone=be
#-----------------------------------------------
We don't use crc4 here, but you can add it if you wish.

Good luck!

K
