ISDN Ordering Codes

Generic ISDN Ordering Codes - a.k.a. National ISDN Capability Packages

Capability Packages A through Q were developed by the North American ISDN Users Forum (NIUF) and implemented in conjunction with the industry's ISDN Solutions '94 event. Since that time, additional Capability Packages have been developed (R through V) with Bellcore.
The National ISDN Registry of Customer Equipment lists equipment models that have enrolled in the NIUF-supported registration process provided by Bellcore.
Contact your USA Regional Bell Service Provider for ISDN Capability Package pricing and ordering information for your home or office.

*** ViewStation supports Package "R" or Package "S".
