Introduction 1 Overview The ACCULINK® 316x DSU/CSU acts as an interface between the T1 digital network and the customer premises equipment, converting signals received from the DTE (Data Terminal Equipment) to bipolar signals that can be transmitted over T1 lines. Typical applications include shared access to network-based services, Local Area Network (LAN)/Wide Area Network (WAN) interconnection, and fractional T1 network applications.
PAGE 18
1. Introduction Asynchronous (async) terminal interface support. Telnet access for remote async terminal operations. Network management provided through industry-standard Simple Network Management Protocol (SNMP). DTE Drop/Insert (DSX-1) Interface The DTE Drop/Insert interface allows DTEs/PBXs that support the DS1 signal format to share the T1 network with other high-speed equipment. This is available on 2-port and 4-port DSU/CSUs.
PAGE 19
1. Introduction SNMP Management Support SNMP is a network management protocol that is used to monitor network performance and status, and to report alarms (i.e., traps). To function, SNMP requires a manager consisting of a software program housed within a workstation or PC; an agent consisting of a software program housed within a device (e.g., the DSU/CSU); and a Management Information Base (MIB) consisting of a database of managed objects. The DSU/CSU can be managed by any industry-standard SNMP manager.

SNMP MIB Objects E Overview This appendix describes the Management Information Base (MIB) objects that are supported by the DSU/CSU and provides a correlation between front panel commands and MIB objects (Table E-1, SNMP MIB to Front Panel Command Cross-Reference). The DSU/CSU supports the following MIBs: MIB II (RFC 1213) Defines the general objects for use in Transmission Control Protocol/Internet Protocol (TCP/IP) internets and provides general information about the DSU/CSU.
PAGE 216
E. SNMP MIB Objects 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. The MIB II object groups supported or not supported by the 3100 Series devices are as follows: E-2 System Group Supported.
PAGE 217
E. SNMP MIB Objects System Group, MIB II The System Group objects are fully supported by the DSU/CSU. The following sections provide clarification for objects contained in the System Group where it is not otherwise clear how the object definition in MIB II is related to the DSU/CSU. Objects not mentioned are supported as stated in the MIB. System Group – “sysDescr” Object (system 1) This object provides the full name and version identification for the system hardware and software.
PAGE 218
E. SNMP MIB Objects 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. physical(1) – Layer 1 functionality for all interfaces. datalink/subnetwork(2) – Layer 2 functionality (SLIP, PPP) for the COM, AUX, and MODEM ports. internet(4) – Layer 3 functionality (IP) for all management links.
PAGE 219
E.
PAGE 220
E. SNMP MIB Objects Interface Group – “ifDescr” Object (ifEntry 2) This object provides information about the interface. Each interface displays a text string as shown below: Network T1: “Network T1. [Company Name] T1 DSU/CSU, Hardware Version: [CCA number for the CSU board]”. DTE T1: “DTE T1. [Company Name] T1 DSU/CSU, Hardware Version: [CCA number for the CSU board]”. COM: “COM port.
PAGE 221
E. SNMP MIB Objects Interface Group – “ifSpeed” Object (ifEntry 5) This object provides the interface’s current bandwidth in bits per second. The value of this object for each interface is specified as follows: T1 Interfaces: 1,544,000 bps. COM, AUX, and MODEM: The currently configured data rate for the port. Data Ports: The currently configured data rate for the port when the port is allocated to one of the T1 interfaces. If the port is not allocated the data rate is defined as zero.
PAGE 222
E. SNMP MIB Objects 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. The interface is down(2) when an alarm condition is active. The interface is testing(3) when a test is active on the interface. DTE T1: The interface is up(1) when no alarm conditions exist and the interface is enabled.
PAGE 223
E. SNMP MIB Objects Interface Group – Input Counters (objects ifEntry 10 to ifEntry 15) 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.
PAGE 224
E. SNMP MIB Objects IP Group, MIB II The IP Group objects are supported by the DSU/CSU for all data paths which currently are configured to carry IP data to or from the DSU/CSU, including the MODEM, COM, AUX, carrier SNMP bus, EDL, and FDL. All of the objects in the IP Group other than the IP Address Translation table are fully supported. The IP Address Translation table (ipNetToMediaTable) does not apply to the DSU/CSU and will be empty (i.e., have zero entries).
PAGE 225
E. SNMP MIB Objects IP Group – “ipRouteTable” Object (ip 21) The routing table used by the DSU/CSU is supported as a read/write table. Entries in this table may be added, deleted, or changed. You should exercise great caution when adding or modifying routes in the ipRoutingTable. In general, it should not be necessary to add or modify routes in the DSU/CSU. In those cases where it is deemed necessary, the routes should only be added to the connected device (i.e., the device closest to the destination).
PAGE 226
E. SNMP MIB Objects IP Group – “ipRouteDest” Object (ipRouteEntry 1) The ipRouteDest object serves as the index to the routing table. Since indexes for tables must be unique, only one route per destination may appear in the table. To ensure that no duplicate destinations appear in the routing table, the ipRouteDest object of the ipRouteTable will be treated as described in RFC 1354 (IP Forwarding Table MIB): “The destination IP address of this route. An entry with a value of 0.0.0.
PAGE 227
E. SNMP MIB Objects 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). 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. These routes do not age, but will remain unless deleted via SNMP.
PAGE 228
E. SNMP MIB Objects SNMP Group, MIB II The SNMP Group objects that apply to a management agent are fully supported by the DSU/CSU. The following objects apply only to an NMS and return a zero value if accessed.
PAGE 229
E. SNMP MIB Objects Near End Group – “dsx1TimeElapsed” Object (dsx1ConfigEntry 3) Applies to the network interface only. An error status is returned if access is attempted for the DTE Drop/Insert (DSX-1) interface. Near End Group – “dsx1ValidIntervals” Object (dsx1ConfigEntry 4) Applies to the network interface only. An error status is returned if access is attempted for the DTE Drop/Insert (DSX-1) interface.
PAGE 230
E. SNMP MIB Objects Near End Group – “dsx1CircuitIdentifier” Object (dsx1ConfigEntry 8) This object is only supported on the Net T1 Interface. Near End Group – “dsx1LoopbackConfig” Object (dsx1ConfigEntry 9) This object specifies the loopback state of the T1 interfaces. Only the following values are supported by the DSU/CSU. dsx1NoLoop(1) – The T1 interface is not in a loopback state.
PAGE 231
E. SNMP MIB Objects Near End Group – “dsx1TransmitClockSource” Object (dsx1ConfigEntry 12) This object specifies the timing source for the transmit clock for this T1 interface. This object differs from the MIB definition in that it is “read-only” (not read/write) for DSU/CSUs. Only the following values are supported by the DSU/CSU. loopTiming(1) – The recovered receive clock is being used as the transmit clock. localTiming(2) – The DSU/CSU’s internal clock is used being as the transmit clock.
PAGE 232
E. SNMP MIB Objects Near End Group – The DS1 Interval Table Objects (dsx1IntervalEntry) The following DS1 interval 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. dsx1IntervalIndex – The index that identifies the T1 interface. dsx1IntervalNumber – The interval number (1 to 96). dsx1IntervalESs – Errored Seconds for the interval.
PAGE 233
E. SNMP MIB Objects DS1 Fractional Group, DS1/E1 MIB The DS1 Fractional Group consists of the DS1 fractional table. This table (dsx1FracTable) is fully supported by the DSU/CSU and allows channel (time slots) to be mapped between the T1 interfaces and data ports. If an invalid channel map (e.g., two interfaces mapped to a single time slot, one interface mapped to two T1s, etc.) is received, an error will be returned to the SNMP manager.
PAGE 234
E. SNMP MIB Objects General Port Table, RS-232-like MIB The general port table contains general configuration objects for the RS-232-like interfaces. General Port Table – “rs232PortIndex” Object (rs232PortEntry 1) This object contains a unique value for each port and is used as an index into the general port table (rs232PortTable). The values of the rs232PortIndex object vary between models and are listed below.
PAGE 235
E. SNMP MIB Objects General Port Table – “rs232PortType” Object (rs232PortEntry 2) This object is used to identify the port’s hardware type. Only the following values are supported by the DSU/CSU. rs232(2) – Used to identify the MODEM, AUX, and COM ports. rs422(3) – Used to identify synchronous data ports that are configured as EIA-530A or RS-449. V35(5) – Used to identify synchronous data ports that are configured as V.35.
PAGE 236
E. SNMP MIB Objects Asynchronous Port Table, RS-232-like MIB The asynchronous port table contains an entry for the MODEM, AUX, or COM port when the port is configured for asynchronous operation. For the DSU/CSU, the entries in the table that are counters (rs232AsyncPortEntry 6–8) are used to collect statistics and are not supported. Asynchronous Port Table, “rs232AsyncPortBits” (rs232AsyncPortEntry 2) This object specifies the number of bits in a character.
PAGE 237
E. SNMP MIB Objects Synchronous Port Table, RS-232-like MIB The synchronous port table contains an entry for each of the synchronous data ports and the MODEM or COM port when the port is configured for synchronous operation. For the DSU/CSU, the entries in the table that are counters (rs232SyncPortEntry 3–7) are used to collect statistics and are not supported. Synchronous Port Table – “rs232SyncPortClockSource” (rs232SyncPortEntry 2) This object specifies the clock source for the port.
PAGE 238
E. SNMP MIB Objects Output Signal Table, RS-232-like MIB This object contains entries for the output signals that can be asserted by the unit for each of the synchronous data ports. Output Signal Table – “rs232OutSigName” (rs232OutSigEntry 2) This object contains the identification of a hardware output signal. Only the following values are supported by the DSU/CSU. cts(1) – Clear-To-Send. dsr(4) – Data Set Ready.
PAGE 239
E. SNMP MIB Objects Generic Interface Test Table, Generic Interface MIB The test table provides access to additional tests (loopbacks and pattern tests) that are not in the interface group of MIB II. Generic Interface Test Table – “ifExtnsTestType” Object (ifExtnsTestEntry 4) This object is a control variable used to start and stop operator-initiated tests on the interface. It provides the capability to: Start/stop the Monitor QRSS test pattern on the network interface.

IP Network Addressing Scenarios F Overview This appendix describes a means of configuring 31xx Series devices in an Internet Protocol (IP) network to provide SNMP or Telnet connectivity. Since there are many possible network addressing schemes, this appendix describes an addressing scheme for typical customer network management system (NMS) scenarios. This appendix is not intended to be an IP addressing or routing tutorial, and a basic understanding of IP and 31xx Series devices is assumed.
PAGE 248
F. IP Network Addressing Scenarios Scenario 1 The first scenario (Figure F-1, Daisy-Chained Standalone at the Central Site) 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. ETHERNET 135.18.40.1 CO MS PH ER E 361 0 135.18.1.2 135.18.1.
PAGE 249
F. IP Network Addressing Scenarios Scenario 2 The second scenario (Figure F-2, Local Carrier with Remote Standalone) 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.
PAGE 250
F. IP Network Addressing Scenarios Scenario 3 This third scenario (Figure F-3, Local Carrier Connected to Remote Carriers) 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.
PAGE 251
F. IP Network Addressing Scenarios Scenario 4 An alternative addressing scheme, for the network is shown in Figure F-4, Local Carrier Connected to Remote Carriers – an Alternative. 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.
PAGE 252
F. IP Network Addressing Scenarios Scenario 5 Figure F-5, Multiple COM Ports Connected to Different NMSs, 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.
PAGE 253
Front Panel Emulation G Overview The DSU/CSU offers functionality through Front Panel Emulation software that is similar to that provided by the DSU/CSU front panel. The DSU/CSU can either be locally or remotely attached to a 386 or higher PC that has at least 4 MB of RAM. A copy of the DSU/CSU front panel appears on the PC. The functionality of the front panel is available by clicking on the Function keys with the mouse rather than by pressing keys from the actual front panel.
PAGE 254
G. Front Panel Emulation Procedure To install Front Panel Emulation software: 1. Insert the diskette into the appropriate drive. 2. Select File from Program Manager. 3. Choose Run. 4. Type A:INSTALL and click OK. 5. An Information screen appears. Choose Continue to continue the installation. 6. Type the letter of the destination drive, followed by a colon (default is C:), then the appropriate directory name (default is C:\FRONTPAN).
PAGE 255
G. Front Panel Emulation Starting Front Panel Emulation If the DSU/CSU selected is not locally attached to the PC, you must first dial to the remote DSU/CSU before starting front panel emulation. The modem attached to the PC must support AT commands for the Front Panel Emulation software to successfully place the call. Procedure To start front panel emulation: 1. From the PC, open Program Manager from Windows. 2.
PAGE 256
G. Front Panel Emulation 5. Choose either a Local (for near-end DSU/CSU) or Remote (for far-end DSU/CSU) destination. 6. If you chose a Local destination, click on the Execute button. If you chose a Remote destination, enter the telephone number of the far-end DSU/CSU in the Phone Number field, then click on the Dial button. 7. The front panel of the selected DSU/CSU appears on the PC.
PAGE 257
Asynchronous Terminal Operation H Overview You can configure and manage the DSU/CSU from an asynchronous (async) terminal that is configured for 9.6 kbps, 8 characters, no parity, and 1 stop bit. This appendix provides operational examples to help you become familiar with the use of the async terminal for DSU/CSU control. By convention throughout this appendix, examples of screens are shown as they appear with the standalone 4-port DSU/CSU.
PAGE 258
H. Asynchronous Terminal Operation Initiating an Asynchronous Terminal Session Once the appropriate configuration option changes have been made and access is established, the Main Menu screen appears (unless a password is required). Figure H-1, Main Menu Screen, shows the Main Menu screen for a standalone DSU/CSU. The carrier-mounted DSU/CSU shows the 3000 Series carrier slot number under the Customer ID. The slot number field (e.g., Slot: 1) is changed to access specific DSU/CSUs in the carrier.
PAGE 259
H. Asynchronous Terminal Operation Ending an Asynchronous Terminal Session To end the async terminal session from any screen, press Ctrl-a to move from the Screen area to the Screen Function Keys area (Figure H-1, Main Menu Screen), and then select Exit.
PAGE 260
H. Asynchronous Terminal Operation Menu Organization Async terminal menus differ from front panel menus in that they typically do not use abbreviations and, in some cases, provide a more direct access to an option or function. Figure H-2, Menu Organization, shows the organization of the async terminal menu tree.
PAGE 261
H. Asynchronous Terminal Operation Using Asynchronous Terminal Screens There are three types of async terminal screens. Menu screens list selections available through the menu system. Input screens allow you to edit or change information on a screen using screen function keys (Table H-1, Screen Function Keys) or keyboard keys (Table H-2, Keyboard Keys). Display screens show the results from a data collection operation or they display device-specific information.

You cannot edit the Default Factory configuration options, but you can display them. After selecting the set of configuration options to load, the Configuration Edit/Display screen appears (Figure H-6, Configuration Edit/Display Screen).
PAGE 267
H. Asynchronous Terminal Operation Saving Edit Changes Procedure To save edit changes: 1. From the last edit screen, select Save. The Save Configuration To screen appears (Figure H-7, Configuration Save Screen). 2. From the Save Configuration To screen, select a configuration option set (Current, Customer 1, or Customer 2). Save edit changes to the Current area when you want those changes to take effect immediately.
PAGE 268
H. Asynchronous Terminal Operation Establishing Access Security on a Port 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. Passwords can also be enabled for the internal modem and for Telnet sessions. Procedure To establish access security on the communication port: 1.
PAGE 269
H. Asynchronous Terminal Operation Setting a Password In addition to establishing access security on a port (refer to the previous section, Establishing Access Security on a Port on page H-12), the password itself is set. Unless you specify otherwise, the password is null. Procedure To set a password: 1. From the Main Menu screen, select Control. The Control screen appears. 2. From the Control screen, select Administer Password. The Password Entry screen appears (Figure H-9, Setting a Password).
PAGE 270
H. Asynchronous Terminal Operation Entering a Password to Gain Access When access security is required, the Login screen (Figure H-10, Entering a Password) appears before you can access the Main Menu screen. The password must be entered. If the password is valid, the DSU/CSU’s top-level menu appears. If the password is invalid, an invalid password message appears and the screen reappears and waits for password entry.
