Program *66-3 Overview
This program assigns ISDN CO switch type and special call treatment for the ISDN service. Call
treatment includes whether or not operator calls are allowed, if carrier access is allowed, etc. The
ISDN service is similar to trunk type, such as POTS, FX, Tie, outWATS and inWATS.
LEDs 11, 13, 14, 15: Programming for ISDN CO Switch Type
Determine which type of CO switch is providing the PRI service and set the following programs
accordingly. (This is not necessary for Basic Rate Interface (BRI) service.) Most Northern
Telecom DMS ISDN switches follow Northern Telecom’s PRI custom protocol, sometimes
referred to as National ISDN Stardard 1 (NI1). However, some DMS ISDN switches are National
ISDN Stardard 2 (NI2). Most all ISDN switches manufactured by other companies follow the NI2
standard.
