Chapter 1. Introduction Chapter 1 Introduction PRODUCT OVERVIEW The ADTRAN DSU IV ESP (data service unit with embedded SNMP) provides a reliable, high speed data connection for customer data terminal equipment (DTE) through digital data service (DDS) lines. The DSU IV ESP has an embedded SNMP (simple network management protocol) agent that provides complete SNMP access to the unit through an integral SLIP or PPP async port.
Chapter 1. Introduction The DSU IV ESP provides both V.35 and EIA-232 electrical and physical DTE interfaces to accommodate a variety of applications. To ensure a reliable connection, the unit features an extended receiver capability which permits operation over long loops (3.4 miles or 5.5 km of 26 AWG at 56 kbps). The ESP 4-wire SW56 DBU card and the base unit's integrated SW56 capabilities are compatible with AT&T Accunet and Sprint SW56 type services. The V.
Chapter 1. Introduction Figure 1-1 Typical Point-to-Point Application for DSU IV ESP DDS OPERATION DDS is a nationwide service that allows interconnection and transport of data at speeds up to 64 kbps. The local exchange carriers provide the local loop service to DDS customers and may provide data for routing Inter-LATA to an interexchange carrier. In DDS mode, the DSU IV ESP supports 2.4 to 64 kbps DDS service rates yielding DTE rates of 2.4, 4.8, 9.6, 19.2, 38.4 (sync or async), 56 kbps, and 64 kbps.
Chapter 1. Introduction SWITCHED 56 OPERATION This dial-up, 4-wire Switched 56 DDS allows customers to pay for data connection only for the time the unit is active. The regional operating companies provide the 4-wire local loop service to SW56 customers. The DSU IV ESP supports DTE rates of 2.4, 4.8, 9.6, 19.2, 38.4, and 56 kbps (synchronous) and 2.4, 4.8, 9.6, 19.2, 38.4, and 57.6 kbps (asynchronous).
Chapter 1. Introduction requires the optional ESP ethernet card (part number 1204005L1). This card provides a 10baseT ethernet interface to the LAN. TELNET TELNET provides a password-protected, remote login facility to the DSU IV. TELNET allows a user on a network manager to control the DSU IV through the terminal menus. See the chapter Applications and the appendix Terminal Menu Structure for more information. DIAL BACKUP OPERATION The DSU IV ESP's unique DBU cards are field-installable by the customer.
Chapter 1. Introduction V.34 Card The V.34 card has all of a V.32 bis modem's modes of operation, plus V.34 and V.FC modes. This allows the V.34 option to run synchronous rates up to 33.6 kbps as opposed to the V.32 at 14.4 kbps. In asynchronous mode the throughput at 57.6 kbps is less dependent on data types. ISDN Card 1B+D Basic Rate ISDN service provides the customer with a switched 56/64 kbps circuit.

Chapter 4. Applications DIAL BACKUP APPLICATION The DSU IV provides point-to-point connection to the network. With one of the ESP DBU option cards installed, the unit is capable of dial backup, allowing the unit to dial around a failed network. See Figure 4-3. With the DBU options, configure the unit to: • Enter DBU under specific primary network conditions. • Lock out DBU over the weekend and/or at specified times of the day. • Dial a specified number when a DBU activation condition is detected. V.
Chapter 4. Applications Operation During Critical Times The following four conditions will cause a DSU IV ESP to enter dial backup mode: Loss of Sealing Current Sealing current is a low voltage DC current provided by the central office (CO) to prevent corrosion over the copper wires used in the local loop. Sealing current may also be used for local loop testing purposes. An absence of sealing current generally is an indication that the loop is open.
Chapter 4. Applications Operation During Noncritical Times The DSU IV ESP may be configured not to enter dial backup mode if data terminal ready (DTR) is low. This feature prevents the DSU IV ESP from entering dial backup during noncritical times such as nights and weekends. For more information, see the chapter Configuring Dial Options. Weekend and Time of Day Lockout The DSU IV ESP may be configured not to enter dial backup mode based upon the time of day or weekend status.

Chapter 12. Testing and Troubleshooting TROUBLESHOOTING This section is intended to provide a quick and easy means of diagnosing suspected problems associated with local or remotely attached ADTRAN DSU/CSUs. Messages from the DSU/CSU Messages on the LCD display and LEDs gives information concerning the status of the unit and the local loop. If the Alarm LED is On, one or more of the messages shown in Table 12-A are displayed on the LCD.
Chapter 12. Testing and Troubleshooting Troubleshooting New Installs Before initiating diagnostics on a newly installed unit and/or DDS circuit and before contacting ADTRAN Technical Support, please check the items in Table 12-B to ensure the unit is configured properly.
Chapter 12. Testing and Troubleshooting Test Sequence for Troubleshooting New Installs or Existing Circuits If your DSU is suspected of having problems, perform a Self Test to determine whether the unit is in good health. If your DSU is receiving excessive errors requiring retransmission of data, first perform a DTE with Test Pattern to determine whether the unit's internal transmitter and receiver are operating error free.
Chapter 12. Testing and Troubleshooting LOCAL UNIT DIAGNOSTICS The local DSU IV ESP can perform six different tests; see Table 12-C.
Chapter 12. Testing and Troubleshooting Table 12-D DTE With Test Pattern Commands Front Panel 1=2047 PATTERN 2=511 PATTERN _T2&T8 Stress pattern with alternating high and low ones densities. Repeated pattern of 100 octets: 1111 1111, followed by 100 octets: 0000 0000. 4=STRESS PTRN #2 _T3&T8 Stress pattern with alternating medium and low ones densities. Repeated pattern of 100 octets: 0111 1110, followed by 100 octets: 0000 0000. 5=STRESS PTRN #3 _T4&T8 Stress pattern with medium ones density.
Chapter 12. Testing and Troubleshooting DTE & Loop (LL) The DTE & Loop test splits the DSU IV ESP into two separate DTE and loop interface sections and then loops the receive data of each interface back to its respective transmit data. The DTE & Loop test provides a bidirectional loopback at the DSU/CSU. Figure 12-5 illustrates the loopback points and the signal paths for this test.
Chapter 12. Testing and Troubleshooting Loop Only (RT) The Loop Only (RT) test allows the loop interface and a major portion of the DTE interface for the local DSU IV ESP to be tested from the remote site over the actual communication circuit. Figure 12-6 illustrates the loopback point and the signal paths for this test. LOCAL DSU/CSU DTE Interface DTE Tx NET Tx DTE Rx NET Rx TELCO Figure 12-6 Loop Only Test Test Purpose The Loop Only test is used to provide a loopback for network tests.
Chapter 12. Testing and Troubleshooting DTE Only The DTE Only test provides a method for testing both the DTE interface drivers and receivers of the local DSU IV ESP plus its loop transmitter and receiver. For this test, the loop transmit data is connected to the loop receive data at a point close to the physical network interface. This test can be used to verify proper operation between the local DTE and the local DSU IV ESP.
Chapter 12. Testing and Troubleshooting DTE With Test Pattern The DTE with TP (test pattern) test is similar to the DTE Only test described previously except the test pattern is generated using the DSU/CSU internal test pattern generator. This test can be used to detect deficiencies within the internal drivers and receivers of the DSU IV ESP. Figure 12-8 illustrates the loopback point and the data paths for this test.
Chapter 12. Testing and Troubleshooting Interpreting Test Results If the unit is functioning properly, the DSU IV ESP displays: DTE WITH TP TST ERR=XX The first line of the display indicates the type of test being performed, while the second line of the display indicates the number of errors accumulated by the test pattern detector. If errors occur during this test, the test error count can be reset to zero by pressing 1.
Chapter 12. Testing and Troubleshooting Test Pattern The Test Pattern option converts the local DSU IV ESP into a BERT tester for the purpose of testing the DDS circuit. If this test is used, the remote DSU/CSU must be in loopback or transmitting a test pattern. Figure 12-9 illustrates the data paths for this mode.
Chapter 12. Testing and Troubleshooting Self Test The Self Test verifies current operation of the DSU IV ESP. It can be performed at any time and is recommended if there is any question about the DSU's health. Test Purpose The purpose of this test it to determine if the DSU is functioning properly. Interpreting Test Results Once Self Test is activated, the LEDs cycle on and off as the system runs the self test.
Chapter 12. Testing and Troubleshooting REMOTE UNIT DIAGNOSTICS A remote DSU IV ESP can perform seven different tests; see Table 12-E.
