Setting the ISDN PRI Switch Mode

If you select a Span Type of Regular ISDN PRI or Custom ISDN PRI in the T1 PRI Configuration Window, use the following guidelines to set the ISDN PRI Switch mode.

Figure 13. T1 PRI Switch Mode

The top four settings are used for a connection to a CO switch:

AT&T 4ESS PRI

AT&T 5ESS PRI

NT DMS-100 PRI

NI-2 PRI (default)

The bottom four settings are used for a PRI tie trunk configuration where two AltiWare systems are connected back to back. In such a configuration, one AltiWare system must be configured as Network and the other as User. For example, set one to NI-2 PRI Network and the other to NI-2 PRI.
