ACCULINK 316x DSU/CSU E-2 January 1997 3160-A2-GB21-50 MIB II (RFC 1213) The objects defined by MIB II are organized into 10 different groups. The DSU/CSU implements only those groups where the semantics of the group are applicable to the implementation of a DSU/CSU.
SNMP MIB Objects E-3 3160-A2-GB21-50 January 1997 System Group – “sysServices” Object (system 7) This object provides a value which indicates the set of services that are potentially offered by the DSU/CSU. Only the following values are supported.
ACCULINK 316x DSU/CSU E-4 January 1997 3160-A2-GB21-50 The supported ifIndexes for the 3161 DSU/CSU are: • Net T1 • DTE T1 • COM port (if configured) • DCE port 1 • DCE port 2 (if configured) Interface Group – “ifDescr” Object (ifEntry 2) This object provides information about the interface.
SNMP MIB Objects E-5 3160-A2-GB21-50 January 1997 Interface Group – “ifOperStatus” Object (ifEntry 8) This object specifies the current operational state of the interface. The value of this object for each interface is defined as follows: Network T1: The interface is up(1) when no alarm conditions exist.
ACCULINK 316x DSU/CSU E-6 January 1997 3160-A2-GB21-50 Interface Group – Output Counters (objects ifEntry 16 to ifEntry 21) These objects collect statistics on the data received by the COM port, the AUX port, and the MODEM port when these ports are configured as SNMP management links.
SNMP MIB Objects E-7 3160-A2-GB21-50 January 1997 The following objects are defaulted if not specified in the set PDU used to add a route. • ipRouteMetric1 – Defaulted to 1 hop. • ipRouteMetric2 – Defaulted to current slot for carrier devices and –1 for standalone devices.
ACCULINK 316x DSU/CSU E-8 January 1997 3160-A2-GB21-50 IP Group – “ipRouteAge” Object (ipRouteEntry 10) This object is implemented as a read-only object in the DSU/CSU. In the DSU/CSU, it reflects the value of the route’ s time-to-live (in seconds).
SNMP MIB Objects E-9 3160-A2-GB21-50 January 1997 All four tables are fully supported for the network interface. Since statistics are not kept for the DTE Drop/Insert (DSX-1) interface, only the DS1 Configuration table is fully supported.
ACCULINK 316x DSU/CSU E-10 January 1997 3160-A2-GB21-50 • dsx1LineLoop(3) – Specifies that a Line Loopback (LLB) is active for the network interface or a DTE Loopback (DLB) is active for the DTE Drop/Insert (DSX-1) interface.
SNMP MIB Objects E-1 1 3160-A2-GB21-50 January 1997 Near End Group – The DS1 Current T able Objects (dsx1CurrentEntry) The following DS1 current table objects are provided for the network interface only .

ACCULINK 316x DSU/CSU F-2 January 1997 3160-A2-GB21-50 Scenario 1 The first scenario ( Figure F-1 ) is a series of standalone 31xx Series devices daisy chained together , with remotes connected via the FDL. In this scenario, all 31xx Series devices are on the same subnet (135.
IP Network Addressing Scenarios F-3 3160-A2-GB21-50 January 1997 Scenario 2 The second scenario ( Figure F-2 ) is a carrier communicating with standalone remotes. This scenario is similar to the previous one, treating the carrier devices as the daisy-chained devices.
ACCULINK 316x DSU/CSU F-4 January 1997 3160-A2-GB21-50 Scenario 3 This third scenario ( Figure F-3 ) shows a local carrier connected to remote carriers that have remote standalones. Each carrier must be on a separate subnet but, as in the previous scenario, the carrier-remote combination can share a common subnet.
IP Network Addressing Scenarios F-5 3160-A2-GB21-50 January 1997 Scenario 4 An alternative addressing scheme, for the network is shown in Figure F-4 . This example uses a subnet mask of FF .FF .00.00 for the COM port in the central-site carrier (only), with all of the remaining subnet masks set to FF .
ACCULINK 316x DSU/CSU F-6 January 1997 3160-A2-GB21-50 Scenario 5 Figure F-5 illustrates multiple COM ports on the same carrier connected to different NMSs. This might be used in service-provider applications, where some of the carrier ’ s circuit cards (and their remotes) are managed by one NMS and other cards are managed by a different NMS.
