Hi Antonios

Can you revert back whether you have multiple locations connected onto the Channelized E1 port ?

If thats the case then you can configure the ISDN PRI accordingly so that when any of the remote locations goes off then your PRI will be able to support the backup line triggerd by either the PRI end or by the remote end...



Thanks for the reply, this customer has a point to point WAN link using all 30 channels on the channelized E1 making up the 2Mbps. They are now wanting to back this up with a seperate ISDN PRI interface that must dial all 30 channels in the event of a channelized E1 failure.

Hope it makes sense ?

you can use Pri as a back up to E1.

You can use the command back interface under Controllers e1.
