I am trying to configure NFAS with DMS250 but it does not look like that switchtype is supported. Is there an alternate switchtype that is compatible or do I need to have carrier change?

Hi Mark,
According to the info I have read, DMS-250 is a supported switchtype. Have a look;
ISDN NFAS Prerequisites
NFAS is only supported with a channelized T1 controller and, as a result, must be ISDN PRI capable. Once the channelized T1controllers are configured for ISDN PRI, only the NFAS primary D channel must be configured; its configuration is distributed to all the members of the associated NFAS group. Any configuration changes made to the primary D channel will be propagated to all NFAS group members. The primary D channel interface is the only interface shown after the configuration is written to memory. The router must connect to either an AT&T 4ESS, Northern Telecom DMS-100 or DMS-250, or National ISDN switch type
