For ISDN dial-up applications, a terminal adapter is used instead of a
modem. Metasys supports the Hayes System Adapter. The System
Adapter connection is made to Port 2 of the NCM. The System Adapter
requires configuration, which is described under ISDN Adapter
Configuration in the Operator Workstation Technical Bulletin
(LIT-636013).
Figure 15 shows the cable for connecting the NCM (Port 2) to the Hayes
System Adapter.
