I going to be moving into a locaiton that has a dynamicvoice and data NxT1(PRI) the carrier is installing. The carrier is providing the cisco 1800 series router. I will most likley be getting a FE handoff from the carrier...How do I go about setting up the UC520 to handle this? The carrier will be doing the multililnk. I've done this with single T1's and a CSU, but if I'm not setting up the multilink, how would I go about setting up the UC520 to deal with this type of connection?
