Additional FrameSaver SLV 9128-II Features

1. About the FrameSaver SLV

—When the SLV Sample Interval is set to 10 seconds, provides advance detection of network problems before a DLCI Down indication is received, to minimize data loss.

—Provides customer premises equipment (CPE) with a Backward Explicit Congestion Notification (BECN) when backup bandwidth is not sufficient for the traffic, allowing the CPE time to slow traffic to the ISDN before the network starts discarding data.

—Supports Frame Relay Forum Multilink Frame Relay Implementation Agreement – FRF.15 so backup bandwidth can be increased by aggregating multiple B-channels over the ISDN link.

—Supports collection of call and call attempt statistical information that can be viewed from the menu-driven user interface or via SNMP, and supports alarm generation and call security, as well.

—Provides test call capability on ISDN backup links so ISDN and DBM function can be verified before there is an actual primary link failure and switched over to the backup link. Periodic tests are recommended, which can be performed from the menu-driven user interface, or through SNMP commands. Multiple Last Cause Values are also provided to assist in troubleshooting ISDN problems.
