Change interface from t1 to e1

[kbarclay]

Hi,

I'm trying to set up a Netvanta 644 to terminate SIP traffic to a carrier network.  I need to have the box set to use e1 rather than the default t1 but I'm struggling to see how this is done.  I've had  read through the documentation and I've found how to configure the e1 specific parameters but I can't seem to find how to set it to e1 in the first place.

Any tips would be great, thanks.

When creating the interface use “interface e1”.

Example:

interface e1 0/1

description PRA 1

timing-domain 1

system-timing primary

sa4tx-bit 0

tdm-group 1 timeslots 1-31 speed 64

shutdown

Thanks for that unified but that throws an error for me:

644(config)#interface e1 0/1

%------------------------^

No such interface.

I do have a t1 interface defined.  Does this need to be removed?

interface t1 0/1

  timing-domain 1

  no shutdown

Yes you need to remove the t1 and then add e1.

Thanks again.  Would you be able to tell me the command to remove it?  I tried using "no interface t1 0/1" but the command wasn't recognised.

I had a look at the command help suggestions and it doesn't seem to list t1 as a type I can remove:

644(config)#no interface

fdl                    - Delete a fdl virtual interface

loopback               - Delete a loopback virtual interface

pri                    - Remove PRI interface

Sorry to bug you but this is driving me around the bend.

Thanks.

Hello and thanks for posting to our forum.

It is likely that you cannot change to E1 interfaces because the County Setting is the United States, which uses T1 interfaces.  Verify this with the show system command:

Geoff,

thanks for that - I've done that and have my e1 ports now.

Not where I thought it was going to be!
