Need help with IUA config on Cisco 5300 (or other trunking gateway)

I would very much appreciate someones help in configuring the NFAS
primary D-channel on one channelized T1 controller 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

clock source line secondary 1

linecode b8zs

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

linecode b8zs

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

!

controller T1 3

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.
