Introduction 1 Overview The ACCULINKr 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.
Introduction 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. Asynchronous Terminal Interface Support The DSU/CSU can be configured and managed from an asynchronous (async) terminal. The asynchronous terminal’s full screen display uses a menu hierarchy to perform device-control operations.
Introduction Physical Description The DSU/CSU front panel (Figure 1-1) contains twelve light-emitting diodes (LEDs) and six test jacks. The LEDs are described in Front Panel LEDs in Chapter 3, Operation. The test jacks are described in Test Jacks in Chapter 5, Monitoring and Testing. The DSU/CSU rear panel (Figure 1-2) contains the connectors required for the operation of the DSU/CSU. The connectors and their functions are listed in Table 1-1.

ON : DTR is being asserted by the synchronous data DTE. OFF : DTR is not being asserted. TXD Yellow Monitors activity on interchange circuit BA (CCITT 103) – Transmitted Data. This is the data sent from the synchronous data DTE to the data port on the DSU/CSU.
Operation Initiating an Asynchronous Terminal Session You can configure and manage the DSU/CSU from an asynchronous terminal that is configured for 9.6 kbps, 8 characters, no parity, and 1 stop bit. You can connect the asynchronous terminal directly to the COM port of the DSU/CSU, or you can establish a remote connection using dial-in or Telnet access. Once the appropriate access is established, the Main Menu screen (Figure 3-2) appears (unless a password is required).
Operation Recovering Asynchronous Terminal Operation If the DSU/CSU is misconfigured, leaving it in a state that does not support asynchronous terminal operation, use the following recovery procedure. " Procedure 1. Power cycle the DSU/CSU, waiting for the completion of the power-on self-test. 2. Press the asynchronous terminal’s Return key five times in succession.
Operation Menu Organization Figure 3-3 shows the organization of the asynchronous terminal menu tree.
Operation Using Asynchronous Terminal Screens There are three types of asynchronous terminal screens. H Menu screens list selections available through the menu system. H Input screens allow you to edit or change information on a screen using screen function keys (Table 3-5) or keyboard keys (Table 3-6). H Display screens show the results from a data collection operation or they display device-specific information. The asynchronous terminal supports character matching for entering values in fields.
Operation Table 3-6. Keyboard Keys Keyboard Key Usage Ctrl-a Moves the cursor between the Screen area and the Screen Function Keys area. Esc Returns to the previous screen. Tab Moves the cursor to the next field. Back (Shift) Tab or Ctrl-k Moves the cursor to the previous field.

System Group – “sysLocation” Object (system 6) This object provides the physical location of this node. 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. H physical(1) – Layer 1 functionality for all interfaces.
SNMP MIB Objects Interface Group – “ifIndex” Object (ifEntry 1) This object provides the index into the ifTable and typically into tables in other MIBs also. The values of the ifIndex object do not vary between models even though not all indexes are supported for a particular model. When an unsupported index is accessed, “noSuchName” is returned.
SNMP MIB Objects Interface Group – “ifType” Object (ifEntry 3) This object identifies the type of the interface based on the physical/link protocol(s) immediately below the network layer. Only the following values are supported by the DSU/CSU: H ds1 – Used for the network and DTE Drop/Insert (DSX-1) interfaces. H propPointToPointSerial(22) – Used for the synchronous data ports. Used for the COM port when the port is not configured as the SNMP management interface.
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.
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 when it is configured as an SNMP management link.

The following two transmission group objects are supported by the DSU/CSU. H ds1 (transmission 18) – The transmission object supported on the T1 interfaces.
SNMP MIB Objects Near End Group, DS1/E1 MIB The DS1 Near End Group consists of the following four tables: H DS1 Configuration H DS1 Current H DS1 Interval H DS1 Total 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.
SNMP MIB Objects Near End Group – “dsx1SendCode” Object (dsx1ConfigEntry 7) This object specifies the test patterns/codes being sent over the network interface. These tests are not supported on the DTE Drop/Insert (DSX-1) interface. Only the following values are supported by the DSU/CSU. H dsx1SendNoCode(1) – Specifies that the interface is sending normal or looped data. Setting the interface to this value stops an active “send pattern” test on the interface.

SNMP MIB Objects Asynchronous Port Table, RS-232-like MIB The asynchronous port table contains an entry for the 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. Only the following values are supported by the DSU/CSU.
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 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.
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.

IP Network Addressing Scenario 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.
IP Network Addressing Scenario Standalone at the Central Site The first scenario (Figure F-1) shows a 3162 DSU/CSU at the central site, 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 255.255.255.00. A static route is set in the NMS host to subnet 135.18.1.0. ETHERNET CO MS PH 135.18.40.1 ER E 361 0 135.18.1.2 135.18.1.3 CO MS PH ER E 361 0 NETWORK SUBNET 135.18.40.
IP Network Addressing Scenario Local Carrier with Remote Standalone The second scenario (Figure F-2) is a carrier communicating with standalone remotes. All devices are still on the same subnet, and the subnet mask is 255.255.255.00. A static route still must be set in the NMS host to subnet 135.18.2.0. ETHERNET CO MS PH ER E 361 135.18.40.1 0 135.18.2.17 CO MS PH ER E 361 NETWORK 0 LAN ADAPTER 135.18.2.18 SUBNET 135.18.40.0 COM IP ADDRESS: 135.18.40.3 FT1 SUBNET 135.18.2.
IP Network Addressing Scenario Local and Remote Carriers — Different Subnets 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 255.255.255.00 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.
IP Network Addressing Scenario Local and Remote Carriers — Same Subnet An alternative addressing scheme, for the network is shown in Figure F-4. This example uses a subnet mask of 255.255.00.00 for the COM port in the central-site carrier (only), with all of the remaining subnet masks set to 255.255.255.00. 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.
IP Network Addressing Scenario Multiple NMSs 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 255.255.255.00.
