The FrameSaver NP 64+ Frame Relay Digital Service Unit (FSU) is a special purpose
Digital Data Service CSU/DSU which provides management and diagnostic functions
through Simple Network Management Protocol (SNMP) and other protocols, trans-
ported over a Frame Relay network. It also includes an integral modem which supports
access to the DSU as well as other co-located equipment such as routers. The Frame-
Saver NP 64+ can be factory optioned to include an ISDN Adapter (for Backup and/or
Bandwidth On-Demand) or Second DSU (for additional network capacity or Backup).
Network Service Providers (NSPs) who prefer to have independent management ac-
cess from their end-user networks (customer networks), can utilize the isolated man-
agement PVC designed into the FrameSaver NP 64+ for network demarcation and
diagnostics.
Figure 2-1 shows a system level view of the FrameSaver NP 64+, including manage-
ment transport. As shown in the figure, the Frame Relay network provides Permanent
Virtual Circuits (PVCs) for both the Customer Data and FSU management.
NOTE: FrameSaver NP 64+ is transparent to SVCs (Switched Virtual Circuits).
The FrameSaver NP 64+ can have up to two IP Addresses for management. One IP
Address allows it to communicate with SNMP work stations that have access to the
NSP management PVC. A second IP Address can provide management access via a
customer data (payload) PVC.
FrameSaver NP 64+ can also send SNMP Traps to multiple SNMP Alarm Servers via
the management PVCs. The integral modem is used to dial into the Network Control
Center (NCC) Terminal Server to access the SNMP Alarm Server and report faults that
are prevented from being reported over the PVC management channels. It can also ac-
cept maintenance calls from NCC Work Stations to support operator interaction, and
accept inbound calls from a customer or NCC Work Station to manage co-located de-
vices such as a routers.
