ACCULINK 316x DSU/CSU MIB II (RFC 1213) System Group – “sysDescr” Object (system 1) 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. The MIB II object groups supported or not supported by the 3100 Series devices are as follows: This object provides the full name and version identification for the system hardware and software.
SNMP MIB Objects System Group – “sysServices” Object (system 7) The following are the values of the ifIndexes for all DSU/CSU models: 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. • physical(1) – Layer 1 functionality for all interfaces. • 1–Net T1 • 2–DTE T1 • 3–COM port • 4–Modem port • datalink/subnetwork(2) – Layer 2 functionality (SLIP, PPP) for the COM, AUX, and MODEM ports.
ACCULINK 316x DSU/CSU • propPointToPointSerial(22) – Used for the synchronous data ports. Used for the MODEM or COM port when the port is not configured as the SNMP management interface. The supported ifIndexes for the 3161 DSU/CSU are: • Net T1 • DTE T1 • ppp(23) – Used for the MODEM, AUX, or COM port when the port is configured for PPP. • COM port (if configured) • DCE port 1 • slip(28) – Used for the MODEM or COM port when the port is configured for SLIP.
SNMP MIB Objects Interface Group – “ifOperStatus” Object (ifEntry 8) Data Ports: This object specifies the current operational state of the interface. The value of this object for each interface is defined as follows: Network T1: DTE T1: The interface is up(1) when no alarm conditions exist. The interface is down(2) when an alarm condition is active. The interface is testing(3) when a test is active on the interface.
ACCULINK 316x DSU/CSU Interface Group – Output Counters (objects ifEntry 16 to ifEntry 21) IP Group – “ipAdEntAddr” Object (ipAddrEntry 1) 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. For interfaces that are not configured as an SNMP management link, these statistics are not provided and an error status is returned if access is attempted.
SNMP MIB Objects 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. • ipRouteType – Defaulted to indirect. • ipRouteMask – Defaulted as specified in the MIB description. The following objects are unused in the DSU/CSU and setting them will have no effect on the operation of the IP implementation.
ACCULINK 316x DSU/CSU IP Group – “ipRouteAge” Object (ipRouteEntry 10) SNMP Group, MIB II 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). When displays, a value of 999 represents a route that is retained permanently. For temporary routes, the ipRouteAge object decrements over time. All routes added via an SNMP set of the ipRouteTable are considered permanent routes.
SNMP MIB Objects 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. The “statistic” objects for the DTE Drop/Insert (DSX-1) interface entry in the DS1 Current, DS1 Interval, and DS1 Total tables are always zero (null).
ACCULINK 316x DSU/CSU • 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. Near End Group – “dsx1LineStatus” Object (dsx1ConfigEntry 10) Near End Group – “dsx1TransmitClockSource” Object (dsx1ConfigEntry 12) This object specifies the timing source for the transmit clock for this T1 interface.
SNMP MIB Objects Near End Group – The DS1 Current Table Objects (dsx1CurrentEntry) Near End Group – The DS1 Total Table Objects (dsx1TotalEntry) The following DS1 current table objects are provided for the network interface only. Objects in the table that are not listed are not supported and will return an error status if access is attempted. The following DS1 total table objects are provided for the network interface only.
ACCULINK 316x DSU/CSU Operational Note: The fractional T1 group only allows specification of an entire interface to a particular time slot on another interface (i.e., a time slot on one interface cannot be mapped to a time slot on another interface). This prevents complete mapping of time slots on the DTE Drop/Insert (DSX-1) interface to time slots on the network interface.
SNMP MIB Objects General Port Table – “rs232PortType” Object (rs232PortEntry 2) General Port Table – “rs232PortOutSpeed” Object (rs232PortEntry 6) This object is used to identify the port’s hardware type. Only the following values are supported by the DSU/CSU. This object contains the port’s output speed in bits per second. For the DSU/CSU, the rs232PortInSpeed object has the same value as the rs232PortOutSpeed object.
ACCULINK 316x DSU/CSU Asynchronous Port Table, “rs232AsyncPortParity” (rs232AsyncPortEntry 4) Input Signal Table – “rs232InSigName” (rs232InSigEntry 2) This object specifies the parity used by the port. Only the following values are supported by the DSU/CSU. This object contains the identification of a hardware input signal. Only the following values are supported by the DSU/CSU. • none(1) – No parity bit. • rts(1) – Request-To-Send. • odd(2) – Odd parity. Supported on the COM and MODEM ports only.
SNMP MIB Objects • noTest – Stops the test in progress on the interface. Output Signal Table – “rs232OutSigChanges” (rs232OutSigEntry 4) • testFullDuplexLoopBack – Initiates a DCLB on the interface. Only supported for the data ports. This object is not supported by the DSU/CSU. • testLoopDTLB – Initiates a DTLB on the interface. Only supported for the data ports. Generic-Interface MIB Extensions (RFC 1229) • testMonQRSS – Initiates a Monitor QRSS test on the interface.
ACCULINK 316x DSU/CSU Generic Interface Test Table – “ifExtnsTestResult” Object (ifExtnsTestEntry 5) Where these object identifiers are defined as follows: • wellKnownCodes – OBJECT IDENTIFIER ::= [ifExtensions 5] This object contains the result of the most recently requested test. Only the following values are supported by the DSU/CSU. • none – OBJECT IDENTIFIER ::= [wellKnownCodes 1] • none(1) – No test currently active. • inProgress(3) – A test is currently in progress.

ACCULINK 316x DSU/CSU 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 (135.18.1.0). The subnet mask for each device is FF.FF.FF.00. A static route is set in the NMS host to subnet 135.18.1.0.

IP Network Addressing Scenarios 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. All devices are still on the same subnet, and the subnet mask is FF.FF.FF.00. A static route still must be set in the NMS host to subnet 135.18.2.0. ETHERNET 135.18.40.1 CO MS PH ER E 361 0 135.18.2.17 NETWORK CO MS PH ER E 361 0 LAN ADAPTER 135.18.2.
ACCULINK 316x DSU/CSU 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. Once again, the subnet mask is FF.FF.FF.00 for all devices. A static route must be set up in the NMS host for each subnet: 135.18.4.0, 135.18.6.0, 135.18.20.0. 135.18.6.22 135.18.20.
IP Network Addressing Scenarios 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.FF.FF.00. The advantage to this scheme is that only one route must be added to the NMS host (135.18.0.0). 135.19.6.22 135.19.20.
ACCULINK 316x DSU/CSU 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. In this example, each card and remote is on a separate subnet. Also, note that each LAN Adapter connection is on a different subnet. The subnet mask is FF.FF.FF.00.

ACCULINK 316x DSU/CSU Establishing Access Security on a Port 3. From the Configuration Edit/Display screen, select User Interface. The User Interface Options screen appears. Although the password feature is available, it is not required. If used, it ensures access security before control is passed to a device connected to a port. The following procedure is an example only. It shows how to enable the password for the communication port.
Async Terminal Operation Setting a Password This screen is used to add a new password or modify an existing password. In addition to establishing access security on a port (refer to the previous section, Establishing Access Security on a Port), the password itself is set. Unless you specify otherwise, the password is null. 3. Enter a new password in the Password field. The password may be 1 to 8 characters long and may contain the characters 0 through 9, a through z, and/or A through Z.
ACCULINK 316x DSU/CSU Entering a Password to Gain Access • If the password is invalid, an invalid password message appears and the screen reappears and waits for password entry. When access security is required, the Login screen (Figure H-10) appears before you can access the Main Menu screen. The password must be entered.
