Type of Service
The system supports two types of service for DS1 facilities: T1 and Integrated
Services Digital Network Primary Rate Interface (ISDN-PRI). T1 service (the
factory setting) transmits and receives voice, and analog data; ISDN-PRI
transmits and receives voice and analog and digital data.
Table 3-3 shows the kinds of services available through a DS1 facility and
specifies the type of service that supports them. Review the table with your
AT&T representative or authorized dealer and decide the type of service for the
100D module(s).
