Figure 69. 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 MAXCS systems are connected
back to back. In such a configuration, one MAXCS 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.
• AT&T 4ESS PRI Network
• AT&T 5ESS PRI Network
• NT DMS-100 PRI Network
• NI-2 PRI Network
If you select a Span Type of Regular ISDN PRI in the E1 PRI Configuration window, use the following
guidelines to set the ISDN PRI Switch mode.
