Need help in configuring IUA on Cisco 5300

Hello everybody!

I would very much appreciate someones help in configuring the NFAS primary D-channel on one channelized T1 ontroller and binding the D-channel to an IUA application server. Below is an existing

configuration where 10.16.71.220 is an IP address of the Cisco 5300:

iua

AS as5300 10.16.71.220 2577

AS as5300 sctp-streams 2

AS as5300 sctp-t1init 1000

ASP asp1 AS as5300 10.16.233.40 9900

!

!

controller T1 0

framing esf

clock source line primary

linecode b8zs

pri-group timeslots 1-23 nfas_d primary nfas_int 0 nfas_group 0 iua

as5300

!

controller T1 1

framing esf

clock source line secondary 1

linecode b8zs

pri-group timeslots 1-23 nfas_d none nfas_int 1 nfas_group 0

!

controller T1 2

framing esf

linecode b8zs

pri-group timeslots 1-23 nfas_d none nfas_int 2 nfas_group 0

!

controller T1 3

framing esf

linecode b8zs

pri-group timeslots 1-23 nfas_d none nfas_int 3 nfas_group 0

!

Unfortunately my numerous attempts to bring D-channel into service

using TDM equipment have failed, although in case of a non-IUA

configuration (pri-group timeslots 1-23 nfas_d primary nfas_int 0

nfas_group 0) it goes into service immediately.

In addition, I would appreciate if someone could shed some light on why the Cisco 5300 is sending VERSION and GROUP SERVICE messages

in response to the Q.931 SETUP. These two messages are not part of the

Q.931 ITU-T specification, therefore we don't know how to handle

them.

Thanks a lot in advance!

Best regards,

Serge
