DTR question

[dogg1]

I have added a new IPE Shelf and superloop to a CS1000M with 3 network groups. I have 8 superloops and 4 DTR cards existing. With the addition of the new IPE Shelf/Superloop will it require another DTR Card? Is there a formula for adding DTR Cards?

Any help would be appreciated.

Thanks

DTRs are only required for analog phones or trunks when they are dialing. If you are adding analog phones in the new IPE then you may need more DTRs. There are traffic calculations in the Planning and Engineering guide.
