HP MSR2000/3000/4000 Router Series Interface Configuration Guide

19
For the PRI set, the system automatically creates a serial interface numbered serial interface-numbe:15 .
This interface is logically equivalent to an ISDN PRI interface where you can make other configurations
such as:
• DCC
• PPP and PPP authentication
• IP addressing
• Backup center settings if the interface is to be used as a primary or secondary interface for backup
• Firewall
