Thanks for that, but I'm not sure how to apply it to SMS.  Here's a current session RADIUS config for a Bridge 1483 static IP session that currently works fine:

First the RADIUS request for the on demand PVC when traffic is detected:

rad_recv: Access-Request packet from host 172.99.99.12 port 1812, id=4, length=82
	User-Name = "RDBACKS5P0.0.373"
	User-Password = "Redback"
	NAS-Identifier = "1350-Redback"
	Service-Type = Dialout-Framed-User
	NAS-Port = 208942

Login OK: [rdbacks5p0.0.373] (from client 1350redback port 208942)
Sending Access-Accept of id 4 to 172.99.99.12 port 1812
	Service-Type = Dialout-Framed-User
	PVC_Encapsulation_Type = AAA-ENCAPS-ATM-BRIDGE1483
	PVC_Profile_Name = "768-128"
	Bind-Type = AAA-SUBSCRIBE-BIND
	Bind_Sub_User_At_Context = "0115551212 at mycontext"

Then the subscriber request:

rad_recv: Access-Request packet from host 172.99.99.12 port 1812, id=5, length=93
	User-Name = "0115551212 at mycontext"
	User-Password = "Redback"
	NAS-Identifier = "1350-Redback"
	Service-Type = Framed-User
	NAS-Port = 671089013
	Connect-Info = "768-128"

Login OK: [0115551212 at verizon] (from client 1350redback port 671089013)
Sending Access-Accept of id 5 to 172.99.99.12 port 1812
	Framed-IP-Address = 172.99.98.122
	Service-Type = Framed-User
	Context_Name = "mycontext"


I need to figure out how to run PPPoE instead.

Thanks.
