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.
