2 Description
The FrameSaver NP 110 Frame Relay Service Unit (FSU) is a special purpose
T1/FT1 CSU/DSU which provides management and diagnostic functions through
Simple Network Management Protocol (SNMP), transported over a Frame Relay
network. It also includes an integral modem which supports dial-in access to the unit
and to co-located equipment such as routers. The FrameSaver NP 110 can be factory
optioned to include a DSX/Drop Adapter (for integrated voice/data applications) and
an ISDN Adapter (4 BRIs, for Backup and/or additional Bandwidth On-Demand).
Network Service Providers (NSPs) who prefer to have independent management
access from their end-user networks (customer networks), can utilize the isolated
management PVC designed into the NP 110 for network demarcation and diagnostics.
System Level
Figure 2-1 shows a system level view of the FrameSaver NP 110, including
management transport. As shown in the figure, the Frame Relay network provides
Permanent Virtual Circuits (PVCs) for both the Customer Data and FrameSaver NP
110 management.
NOTE: FrameSaver NP 110 is transparent to SVCs (Switched Virtual Circuits).
The NP 110 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 PVC.
FrameSaver NP 110 can also send SNMP Traps to multiple SNMP Stations via the
management PVCs. The integral modem is used to dial into the Network Control Cen-
ter (NCC) Terminal Server to report faults that are prevented from being reported over
the PVC management channels. It can also accept 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 devices such as routers.
