Paradyne 9128-II - Manual (Page 20)

1. About the FrameSaver SLV
1-6 April 2002 9128-A2-GB20-60
— 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.
FrameSaver SLV 9126 units can be equipped with a BRI DBM, which supports
up to two B-channels, which may have a different destination. The DBM is
factory installed in the 9126-A2, and may be field-installed in the 9126-A1.
FrameSaver SLV 9128 and 9128-II 1-slot units can be equipped with a PRI
DBM, which supports up to 23 B-channels, or a BRI DBM. Carrier-mounted
FrameSaver SLV 9128 and 9128-II NAMs support a PRI DBM only.
T Configurable FTP Transfer Rate. Allows you to control the transmit rate
when downloading firmware into the FrameSaver unit and uploading user
history statistics to an NMS (Network Management System) via the COM port
connection or a management PVC so the data can be transferred as a
background task using the standard File Transfer Protocol (FTP) over
extended periods of time using low bandwidth.
T RMON User History Performance Statistics via SNMP Polling. Provides
access to the physical interface and basic frame relay performance statistics
by polling the FrameSaver unit using SNMP (Simple Network Management
Protocol). These statistics are available real-time via the Enterprise MIB and
historically as an RMON2 User History object.
T Frame Relay Traffic Policing. Ensures proper alignment and correlation of
CIR (Committed Information Rate) values between the FrameSaver unit and
the network switch. When this feature is enabled, the unit can enforce CIR and
EIR (Excess Information Rate), marking frames that exceed CIR as DE
(Discard Eligible) using the same method used by the switch.
T Service Provider Support. Provides information and tools useful to network
service providers, which includes the following:
— IP Routing Table – Shows the IP routing table for the FrameSaver unit,
with network as well as host routes, the number of hops to the destination,
the method by which the route was added to the table, the interface used
to get to the destination, and how long the route has been in existence.
— Trap Event Log – Displays the SNMP (Simple Network Management
Protocol) trap event log for the FrameSaver unit from the menu-driven user
interface, with the most recent events first, keeping a running total for all
trap events stored, the amount of time since the event was logged, plus a
description of the trap.
— Troubleshooting PVC – Provides a dedicated troubleshooting
management link that helps service providers isolate problems within their
network.
T ATM VPI/VCI and DLCI Correlation. For networks with both ATM and frame
relay-access endpoints, allows the FrameSaver unit to report the originating
Virtual Path and Channel Identifier (VPI/VCI) in the far-end ATM-access
endpoint where the local DLCI is mapped so they can be correlated for
OpenLane SLV reports.
