980-001-0240B FrameSaver NP 110 User’s Manual - Installation Guide2-1November 20002 DescriptionThe FrameSaver NP 110 Frame Relay Service Unit (FSU) is a special purposeT1/FT1 CSU/DSU which provides management and diagnostic functions throughSimple Network Management Protocol (SNMP), transported over a Frame Relaynetwork. It also includes an integral modem which supports dial-in access to the unitand to co-located equipment such as routers. The FrameSaver NP 110 can be factoryoptioned to include a DSX/Drop Adapter (for integrated voice/data applications) andan ISDN Adapter (4 BRIs, for Backup and/or additional Bandwidth On-Demand).Network Service Providers (NSPs) who prefer to have independent managementaccess from their end-user networks (customer networks), can utilize the isolatedmanagement 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, includingmanagement transport. As shown in the figure, the Frame Relay network providesPermanent Virtual Circuits (PVCs) for both the Customer Data and FrameSaver NP110 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 allowsit to communicate with SNMP work stations that have access to the NSP managementPVC. 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 themanagement 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 overthe PVC management channels. It can also accept maintenance calls from NCC WorkStations to support operator interaction, and accept inbound calls from a customer orNCC Work Station to manage co-located devices such as routers.Figure 2-1 FrameSaver NP 110 Typical Network ApplicationS N M P AlarmS erverN C CL ANN C C Teln etW ork S tatio nP O PC ustom er D ataC enterN etw ork C ontrol C enterIP O v erF ram eC u stom er &M gm t P V C sC u stom erL ANF ram e R elayB ackb o neC u st.P V C sM gm tP V CTerm in al S erverF ram e S w itchD ial Lin eFr am eS aver N P 110C o nso le P o rtS eria l P ort(C us t.
