IFC setting for DMS500

[ohno2]

Hi All,
I've got problems getting my outbound caller ID to pass
through restricted sets:
"..caller does not accept unidentified calls".
I suspect my 11c isn't talking correctly to the switch
on the other side of my PRI line. My IFC is set to NI2.?
In conversation with my vendor (MCI) they suggest the
switch is a DMS 500 (originally Brooks Fiber equipment).

Has anyone heard of the DMS 500 and do you know what the
IFC setting should be for it? (DMS 250 is D250).
Thanks.

We use the D250 IFC on the D Channel. Most DMS500 are two D250 put together.
