Hi guys,
I am trying to connect an OXO with a Cisco Call Manager using the E1 connection. Unfortunately the partner who sold us the OXO has no ideea of the E1 parameters that we should use on the Cisco Router. he also has no ideea about what else we should configure on the OXO in order to enable connection.
Has any of you had any experience with interconnecting an OXO with another PBX or with Call manager using E1?
Any documentation or help would be very much appreciated.
Many Thanks
OXO and Cisco Call Manager interconnecting

First of all you should decide who is master in your configuration (who offers clock to the other one). If OXO is maser must have Syncro Priority greater than cisco or the other way around if else (leave default 0 or so if it receives clock).
Then you should think of what kind of numbering plan you want to use in your network (open or closed) and to define users and public numbering according to this.
In an opened dialing plan let's say that 9 is TG seizure for the networked E1 trunk. If in Cisco side DID translator is defined to translate let's say 3000 as external number into 300 interior number, whwn you dial 9300 from OXO you should reach interior 300 in Cisco.
The other way around in Dialing Plans/Public Nb Plan define for example user start 2000 end 2099 with base 100 which means that external number 2000 reaches interior number 100, 2001 reaches 101 and so on till 2099 reaches 199.
this means that when you send from cisco nb 2004 let's say on E1 you'll reach OXO's internal number 104.
Hope that helps.

First of all many thanks for the quick answer.
I have setup the router with clock source internal and the pbx to use Clock delivery allowed (checked) and Clock Delivery priority 0.
The trunk on the pbx is cheked as public and the other parameters are:
Type: T2
No of B-Chan.: 30
Protocol-Type: EDSS1
Direction of B-Chan.
incoming 0
outgoing 0
bidirectional 30
Allocation: Ascendant
Collision: Slave
Layer 1/ Layer 2 Mode : User
TEI Management: Point to point
Fixed TEI
The router is setup with:
controller e1
clock source internal
pri-group timeslots 1-31 service mgcp
no ip address
encapsulation hdlc
isdn switch-type primary-net5
isdn protocol-emulate network
isdn incoming-voice voice
isdn bind-l3 ccm-manager
no cdp enable
The problem is that I keep getting this message on the router whilst in debug mode:
Jan 25 16:37:31.871: ISDN Se0/0/0:15 Q931: TX -> SETUP pd = 8 callref = 0x0001
Sending Complete
Bearer Capability i = 0x8090A2
Standard = CCITT
Transfer Capability = Speech
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0xA98381
Exclusive, Channel 1
Calling Party Number i = 0x0081, '3326'
Plan:Unknown, Type:Unknown
Called Party Number i = 0x80, '11200'
Plan:Unknown, Type:Unknown
Jan 25 16:37:31.899: ISDN Se0/0/0:15 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x8001 Cause i = 0x81E4 - Invalid information element contents
Everywhere I have looked it seems to be a D channel problem and a CCIE suggested that the OXO is rejecting for some cause the call setup.
It would be of tremendous help if anyone could point me to where to look on the PBX in order to figure out what the problem is.
Many thanks
P.S. the cable used between the router and the PBX is a straight cable and it is pugged in the PBX port of the E1 OXO module.

The default position of the D channels is 1st and 16th on Alcatel OXO. You need to configure that in your router. Also try to change clock priority to 10 for ex. , collision master and make slave your router (clock source external I assume). Try diffrent configurations also.
I think there is a configuration problem on OXO's side also in dialing plan. The PBX doesn't know probably where to route your call.
Try to make contact with a local Alcatel Business partner to send you an ACSE (Alcatel Certified System Expert) to help you with OXO.
It's hard to guess what conf your OXO does have. Unfortunately OXO doesn't posess a tracer eather to see what you are sending to it.
Good Luck.

Checked everything the D channels are ok - it seems that I was trying to use primary-net5 when in fact the OXO speaks qsig basic call.
The dialing plan seems ok in fact I got it to the point where i can call from either side BUT - there is no sound. So I call (whilst calling if noone picks up at the other end I do not hear ringing in the head phone) - and if someone picks up we do not hear each other.
The call seems to be establishing correctly in fact when hanging up the router debug shows Normall Call Clearing.
Any other clues...? Anybody?
