T3SU 300 User Manual 61202217L1-1C
Chapter 1 Introduction PRODUCT OVERVIEW The T3SU 300 is a multiport DSU/CSU (data service unit/channel service unit) that provides access to T3 services. The unit provides a cost-effective, versatile approach for migrating T1 services to T3. The TDM (time division multiplexer) multiport design allows you to share the cost of a T3 line between multiple applications.
Chapter 1. Introduction Complete configuration, diagnostics, and performance monitoring are available through SNMP, Telnet, or a VT100 terminal interface. This connection can be made via Ethernet, a local EIA-232 link, or through the built-in V.34 modem. Advanced dial-out on trap capabilities through the built-in modem allow the T3SU 300 to contact remote hosts and alert them to DSX-3 network conditions (without dedicated management connections).
Chapter 1. Introduction (LAN) port. The T3SU 300 supports the MIB-II standard, RFC 1213, and the ADTRAN Enterprise Specific MIB. MIB files are available from ADTRAN in the support section of the ADTRAN web page at www.adtran.com. The term SNMP broadly refers to the message protocols used to exchange information between the network management system (NMS) and the managed devices, as well as to the structure of device management databases.
Chapter 1. Introduction HSSI Card The optional HSSI card plugs into one of the three card slots on the rear of the T3SU 300. With optional HSSI cards installed, the total 44.2 Mbps bandwidth of the T3 can be divided among the total number of ports to provide multiple data channels over the T3. The total bandwidth of the T3 can be divided among the available ports in any fashion, as long as the divisions are on 75 kbps boundaries. The HSSI card can be hot inserted or swapped.
Chapter 1. Introduction network interface. Up to three cards may be installed into any of the T3SU 300 DTE port card slots. Even though the Quad DSX-1 interface card allows you to transport T1 information, the T3SU 300 still operates the DS3 interface in an unchannelized fashion. Therefore, your DS3 network provider must supply you with an unchannelized, point-to-point DS3. Ethernet Bridge Card The optional Ethernet Bridge interface card plugs into the card slots on the rear of the T3SU 300.

Chapter 6 Diagnostics The DIAGNOSTICS menu allows you to initiate loopback and BERT tests from the T3SU 300. Figure 6-1 on page 90 shows the main DIAGNOSTICS menu. Perform tests for the entire DS3 or for an individual DTE port. If a Quad DSX-1 card is installed, activate loopback tests for an entire card (all four DSX-1s) or for an individual DSX-1 port. No diagnostics are available for the Ethernet Bridge card.
Chapter 6. Diagnostics Loopback tests may be performed simultaneously on all four DTE ports. Figure 6-1.
Chapter 6. Diagnostics DS3 Access the DS3’s diagnostic options by selecting 1 from the main DIAGNOSTICS menu. The menu in Figure 6-2 appears. Figure 6-2. DS3 Diagnostics Menu Data Mode Ends a test already in progress for this port. DS3 Payload Loopback During this test, all payload information is re-framed and looped back towards the network. See Figure 6-3 on page 92 for a block diagram illustrating the loopback point and the signal paths for this test.
Chapter 6. Diagnostics T3SU 300 DTE Figure 6-3. DS3 Payload Loopback Test Line Loopback This test allows the loop interface (LINE) section of the local T3SU 300 to be tested from the remote T3SU 300 over the actual T3 circuit. Testing from the remote end of the circuit is performed by using a 511 test pattern or DTE data generated by the remote host. With this test, the T3SU 300 transceiver receives data from the network and loops it back toward the network through its transmitter.
Chapter 6. Diagnostics BERT Select BERT to perform a bit error rate test over the entire payload bandwidth. Only one BERT test may be performed at a time. Remote DS3 Loopback This selection initiates a DS3 Loopback test for the remote unit. The DS3 Loopback test is described on page 91. Remote Loopback with BERT This selection initiates a DS3 Loopback test for the remote unit and sends/checks the BERT pattern over the entire DS3 payload bandwidth.
Chapter 6. Diagnostics HSSI and V.35 Diagnostic Options The menu in Figure 6-5 appears if the selected DTE port is HSSI or V.35. Descriptions of the menu selections follow the figure. Figure 6-5. HSSI or V.35 Port Diagnostics Menu Data Mode Ends a test already in progress. Payload Loopback This selection initiates a PAYLOAD LOOPBACK test for all data on the selected port rather than for the entire DS3. During this test, the data is looped back in the network direction.
Chapter 6. Diagnostics T3SU 300 MUX DTE Figure 6-6. Payload Loopback Test Payload BERT This selection performs a bit error rate test on the selected port. This test in non-intrusive to the other three ports. Only one BERT test may be performed at a time. This test is normally performed from the remote and local ends simultaneously to determine whether the errors are coming from the transmit or the receive direction. See Figure 6-7. T3SU 300 MUX BERT OUT DTE BERT IN Figure 6-7.
Chapter 6. Diagnostics T3SU 300 MUX DTE Figure 6-8. DTE Loopback Test Payload and DTE Loopback Select this test to perform payload and DTE loopbacks simultaneously. The individual tests are described on page 91 and page 95. See Figure 6-9 for a block diagram illustrating this test. T3SU 300 MUX DTE Figure 6-9. Payload and DTE Loopback Test Remote Port Payload Loopback This selection initiates a Payload Loopback on the remote T3SU 300 for all data on the selected port.
Chapter 6. Diagnostics the remote T3SU 300 are the same as the Payload Loopback test for the local T3SU 300 (shown in Figure 6-6 on page 95). Quad DSX-1 Diagnostic Options The menu in Figure 6-10 appears if the selected port is a Quad DSX-1. Descriptions of the menu selections follow the figure. Figure 6-10. Quad DSX-1 Diagnostics Menu Data Mode Ends a test already in progress.
Chapter 6. Diagnostics #x Payload Loopback During this test, all payload information on the selected DSX-1 interface is reframed and looped back towards the DTE. See Figure 6-11 for an illustration of this test. T3SU 300 Quad DSX-1 Elastic Store Framer/Formatter Jitter Attenuator DSX-1 DS3 MUX T3 Figure 6-11. DSX-1 Payload Loopback Test #x Framer Loopback During this test, all information from the network side (DS3) for the selected DSX-1 interface is looped back towards the network.
Chapter 6. Diagnostics #x Local Loopback During this test, all information from the network side (DS3) for the selected DSX-1 interface is looped back towards the network. This test is similar to the Framer Loopback test (described previously), with the exception that this test penetrates the circuitry deeper into the Quad DSX-1 interface card. See Figure 6-13 for an illustration of this test. T3SU 300 Quad DSX-1 Elastic Store Framer/Formatter Jitter Attenuator DSX-1 DS3 MUX T3 Figure 6-13.
Chapter 6. Diagnostics Payload Loopback During this test, all data for the selected DSX-1 interface is looped back to the far-end unit. The end result is all DSX-1 interfaces of the far-end unit are looped back. All other ports are unaffected. See Figure 6-15 for an illustration of this test.

Chapter 6. Diagnostics DTE Loopback During this test, the combined information from the four DSX-1 interfaces is locally looped at the multiplexer of the T3SU 300 back towards the Quad DSX-1 interface card. The end result of this test is a loopback of all DSX-1 interfaces towards the DTE. See Figure 6-16 for an illustration of this test. T3SU 300 Quad DSX-1 DSX-1 T3 DS3 MUX Figure 6-16.

Payload and DTE Loopback Test Remote Port Payload Loopback During this test, the local unit commands the far-end unit to perform a payload loopback test for the selected Quad DSX-1 interface card. This results in all of the DSX-1 interfaces in the local unit being looped back. See Figure 6-18 for an illustration of this test.
Chapter 6. Diagnostics BERT Configuration The following options apply to any of the tests involving BERT testing. Pattern Select the desired test pattern for the BERT test (see Figure 6-19). The internal test pattern generator can be configured for the following types of test patterns: • All zeros • All ones • 2^15-1 • 2^23-1 The test pattern is used to independently test the operation of the framing circuitry and the network interface of the T3SU 300.
Chapter 6. Diagnostics Invert Pattern If set to ENABLE, the T3SU 300 inverts the transmitted and received BERT test pattern. This allows the unit to be compatible with test equipment which generates inverted BERT patterns. BERT Information Fields The following five fields provide information about the most recently issued BERT test. These fields appear in the main DIAGNOSTICS menu (shown in Figure 6-1 on page 90). Port Displays which port is transmitting and receiving the BERT pattern.
Chapter 7 Applications This chapter provides examples of some common T3 applications. The examples include a single port DSU/CSU full T3 bandwidth application, a point-to-point multiport application (page 106), a fractional T3 application (page 108), a remote SNMP management application (page 110), and a voice application (page 111). The configuration selections given in these examples may need modification based on your network configuration.

Chapter 7. Applications REMOTE SNMP MANAGEMENT APPLICATION A remote T3SU 300 can be managed by a local management station if the remote unit is assigned its own IP address. This address must be assigned at both the near and far ends. Also, the DATA LINK option must be enabled on both units. In this application example (shown in Figure 7-4) a local T3SU 300, connected to the same LAN as the management station, provides management access to a remote T3SU 300.
Chapter 7. Applications VOICE APPLICATION This voice application is similar to the point-to-point multiport application (described on page 106). This application (shown in Figure 7-5) uses two of the four DSX-1 ports on the Quad DSX-1 card to transport PBX data, including voice channels, through the same T3 as the data.
