Connecting a Cisco 3600 to a TN556 BRI LINE

Connecting a Cisco 3600 to a TN556 BRI LINE

Connecting a Cisco 3600 to a TN556 BRI LINE

Does anybody know how to connect a 3600 Cisco Router to a TN556 BRI-LINE or where can I find some documents about how to do it?

The cisco Router is now working OK connected directly to a S/T interface but, when I connect the BRI Interface of the Router to the Definity WCBRI station, is imposible to establish the connection.

Please, I need some help.

RE: Connecting a Cisco 3600 to a TN556 BRI LINE

Do you have data-module switched ON on first page of the wcbri station form?
And check country protocol. I use data-module form (not station) and we have Cisco 2610 but I think it will no big difference with BRI ports. In station form (or in data module form) we have CountryProtocol -1, XID-N, Fixed TEI-N, Endpnt Init-N. In Cisco config you set the US ISDN protocol (i don't remmeber what exactly 5ess or US-National or something like that).

I'm in Europe so the options will be different, no??

RE: Connecting a Cisco 3600 to a TN556 BRI LINE

Very likely the protocol you would choose is ETSI.
The second parameter that needs to be correct is
the TEI configuration. Enter a zero for Point-to-point
or n for automatic TEI (Which is usualy done in a
Point-to-multipoint configuration). Do not use
XID, as this is US parameter.

I have a Cisco 2611 connected to the BRI line on the Definity. I am based in the UK, so have Euro setup. Create a data module as follows:

                               DATA MODULE

  Data Extension: 1130            Name: ISDN Support Line 1        
            Type: wcbri            COS: 1
            Port: 01A0505          COR: 1                      Multimedia? n
                                    TN: 1  



  Default Duplex: full     Default Mode: sync     Default Speed: 64000

  Default ITC: unrestricted                Default Data Application: M2_A

                               DATA MODULE


                   XID? n     Fixed TEI? n
      Country Protocol: etsi Endpt Init? n

and setup the router with:

interface BRI1/0
 isdn switch-type basic-net3

I have a problem with adding the data modules into a hunt group because the switch only uses one of the BRI lines. The hunt group becomes busy after only half the lines are used. I will post this as a separate question.

RE: Connecting a Cisco 3600 to a TN556 BRI LINE

Thank you very much. I'll try it.

RE: Connecting a Cisco 3600 to a TN556 BRI LINE


A huntgroup wil not do the trick. Say the first call is answered by a datamodule a second call will not be answered as the Definity sees the datamodule "active". What might do
the trick is using a VDN and a vector with a route to step to the datamodule extension.
