Cisco 1721 with WIC-1DSU-56K4 & ISDN card

I am trying to set up a 1721 with a primary 56K frame connection with ISDN back-up. I have set up dozens of these with 1602's but I cannot get the 1721 to take any service-module 56K commands such as

service-module 56K clock rate 56

service-module 56K clock source line

service-module 56K data-coding normal

service-module 56K network-type dds

service-module 56K remote-loopback

I have tried appling these to S0 and S0.1

What an I missing?

I do not have a T1 controller. A show controller only shows the ISDN card which is in the slot WIC 1 and the 56K 4 wire (shows as S0) which is in WIC 0.

I checked the compatability matrix and you are running code that support it for this box

what happens with the question mark ?

router#(conf-if)service-module ?

Re: Cisco 1721 with WIC-1DSU-56K4 & ISDN card

The commands are rejected at the s0.1 level where I typically put them on the 1602. They look like they work at the S0 level but a sho running-config afterward so no trace of the commands,

Raynham#config

Configuring from terminal, memory, or network [terminal]?

Enter configuration commands, one per line. End with CNTL/Z.

Raynham(config)#service-module

Re: Cisco 1721 with WIC-1DSU-56K4 & ISDN card

the reason the commands are rejected on s0.1 is because this is a logical interface . You have to set these parameters on the physical interface

New Member

Re: Cisco 1721 with WIC-1DSU-56K4 & ISDN card

I have set them there but they do not show in the configuration afterwards

Silver

Re: Cisco 1721 with WIC-1DSU-56K4 & ISDN card

If they do not show up it is a default setting

Re: Cisco 1721 with WIC-1DSU-56K4 & ISDN card
