1 1-4 DL3800E Inverse Multiplexer User’s Guide — July 9, 2001
Introduction 2 2 SYSTEM OVERVIEW The DL3800E Inverse Multiplexer bridges the gap between E1 and E3 data services by providing E1 multiplexing of multimegabit (up to Nx1.976 Mbps) DTE data onto two to eight E1 circuits. The DL3800E Inverse Multiplexer is an economical solution to bandwidth intensive applications as it provides multimegabit data transport without the need for E3 circuits.
2 The DL3800E unit features an automatic rate fallback in the event of a failing E1 circuit. If the performance of an E1 circuit is detected to be falling below accepted levels, the DL3800E unit automatically removes the E1 from service, and throttles back the DTE to a data rate corresponding to the remaining E1s. When the alarm condition on the affected E1 has been cleared, the DL3800E unit can automatically restore the E1 and data rate.
2 System Benefits The numerous features of the DL3800E unit provide you with many benefits: • Reliable, full performance access to E1 networks for the widest variety of DTE products • Enterprise wide visibility via SNMP • Local and remote access via front panel, terminal, or telnet • Complete maintenance and diagnostic support via exhaustive alarm, statistic, and test capabilities • Downloadable code provides for on-line upgrade to the DL3800E unit software for both major and minor feature enhancements App
2 FUNCTIONAL DESCRIPTION The base DL3800E unit configuration consists of a motherboard with two (E1) network interface connectors and the DTE connectors (HSSI and V.35/RS449/X.21). Six additional E1 network ports can be added with the addition of from one to three daughterboards, each daughterboard supporting two additional E1 ports. The general operation of the DL3800E unit is explained in the following paragraphs which describe the signal flow and overhead functions.
2 When the incoming signal is framed on the inverse mux frame, the framer will start loading its Dual Port RAM. The address to the Dual Port RAM is derived from the 16-bit inverse mux frame. The software will ask all framers to latch their Dual Port RAM addresses at the same time, and by looking at the addresses, the software can determine which network has experienced the greatest delay. From the receive inverse IMUX framer, the incoming data will go to the receive multiplexer.

3 POWER CABLES AND CONNECTIONS The DL3800E unit can be ordered with an AC or DC power supply. AC Power Connection An AC power cord is supplied with the DL3800E -AC-XXX to provide 120 to 240 VAC power. The power cord receptacle is located on the rear panel of the DL3800E-AC-XXX. For AC power, connect the AC power cord to the DL3800E-AC-XXX, and plug into the nearest AC outlet. DC Power Connection The Quick Eagle Networks DL3800E Inverse Multiplexer can also be powered by a -48 VDC power source.
3 4. Connect the ground (+) wire to the + terminal in the same way. NOTE: The unit is designed to operate with negative voltage; therefore, you must connect the positive terminal to ground. 5. Connect the frame ground terminal to the local earth ground, if required. 6. To minimize disturbance to the wires through casual contact, secure a tray cable near the rack frame using multiple cable ties. Use at least four cable ties, a minimum of four inches apart.
3 E1 NETWORK CONNECTION The eight port connector can be either a DB-9, DB-15, or BNC. The connectors are located on the DL3800E unit back panel for connecting to the E1 networks. Connect the DL3800E unit to each E1 Network using the appropriate cable and connectors, available from Quick Eagle Networks. DTE CABLE AND CONNECTION DTE interface connectors are provided on the back of the DL3800E, a 50-pin SCSI socket receptacle for HSSI compatible DTE, and a DB-25 (E1A-530) socket connector for V.35/X.
3 Direct Connection For direct connection, using the appropriate DE-9 cable, connect the ASCII terminal or SNMP workstation to the DL3800E unit through the Terminal or SNMP connector on the back of the rear panel. The baud rate, parity bit, and stop bit settings must match those of the terminal: baud rate, 9600; eight bits, no parity and two stop bits.
3 Daisy Chaining Multiple DL3800E units can be daisy-chained together through the Terminal Port to provide centralized network monitoring and management capabilities. A ribbon-type cable with DB-9 connectors is available from Quick Eagle Networks for daisy-chaining your DL3800E units. You can order specific cables to daisy-chain four units (Part No. 154-00051-01), eight units (Part No. 154-00052-01), or twelve units (Part No. 154-00053-01).

SNMP Configuration Through the SNMP CONFIGURATION MENU, you configure the Network Manager (NMS) port on the rear panel of the DL3800E, setting various addresses and configurable items required for operation with an SNMP Network Manager.
4 Table 4-9 SNMP Configuration Options Option Description/Action Unit IP Address The Unit IP Address is a 32-bit quantity which uniquely identifies the node in the IP network. This address is used by the SNMP manager to access information from the node. To set or change the Unit IP Address, move the highlight bar to Unit IP Address, and enter a 32-bit quantity. Press Enter when finished.
4 Table 4-9 SNMP Configuration Options (Continued) Option Description/Action SNMP Baud Rate This feature selects the SNMP port’s baud rate. To set or change the SNMP port baud rate, move the highlight bar to SNMP Baud Rate, and press the Space Bar to toggle between the options until the desired speed appears. The options are: 300; 600; 1200; 2400; 4800; 9600; 19,200 and 38,400.
4 However, it is important to note that the remote IMUX’s “Unit IP Address” parameter must be set to some non-zero value in order to respond to the bridged IP packets. SNMP trap packets from the remote IMUX unit are modified upon receipt. The source IP address field in the trap packet is modified to the “Remote IP Address” parameter; then the packet is forwarded out the NMS/SLIP link.
4 Tests The TESTS MENU allows you to initiate or stop four types of loopbacks for each individual network port: DTE/NETWORK LOOPBACK for the DTE, PAYLOAD LOOPBACK, LINE LOOPBACK, and LOCAL LOOPBACK. For troubleshooting suggestions see “Troubleshooting the DL3800E” on page 63. To access the TESTS MENU, move the highlight bar to TESTS in the DL3800E unit Main Menu, and press Enter. Figure 4-20 is an example of the TESTS MENU.
4 To initiate a test, use the CURSOR keys to move the highlight bar to DTE/Network Loopback or a Payload or Line Loopback on a selected port. Use the space bar to toggle between OFF and ON until ON appears in the display. When that selection appears in the display, move the highlight bar to CONFIRM, and press the Enter key. To cancel a test that is running, move the highlight bar to DTE/Network Loopback. Use the space bar to toggle between the options until OFF appears in the display.
4 Figure 4-21 Loopbacks within the DL3800E unit Remote Loopback Detection The DL3800E has the capability of detecting loopbacks which are set on the remote 3800E or somewhere in the network line. When a remote loopback is detected, the 3800E removes the port from the DTE data bundle and reduces the DTE data rate, sets the port LED to yellow and changes the port status in the Alarms & Status menu to read “Remote Lpbk”. It also generates an SNMP alarm: enRemoteLpAlarm.
4 . WARNING: The E1 Loopback tests will result in removal of the E1 port from service unless the port is configured for “Install/Test Only” mode. In this mode, a port in loopback will remain in service, which will disrupt traffic. Manual Network Restoration The DL3800E’s E1 ports are normally set to auto restore. However, you may choose to individually restore E1 networks after they fail, through the MANUAL NETWORK RESTORATION MENU. NOTE: Manual restore will only work under the following conditions: 1.

Front Panel Interface 5 5 GENERAL The front panel (Figure 5-1) features a 16 character vacuum fluorescent display and four buttons that help you to move through the various menus to configure the unit, perform tests, and obtain vital performance data. The front panel also features six LEDs for the DTE port, one for each of the E1 networks, three for the DL3800E unit status and one for Network Test.
5 The front panel buttons are also used for Alarm Cutout. When an alarm condition occurs, the External Alarm Output contacts close. This typically actuates external alarm indicators such as bells or alarm lights. Pressing any of the four front panel buttons clears the condition, and turns off the external bell or light. Exit Button The EXIT button is used to cancel operations or exit to a higher level menu loop from a submenu loop. This button doubles as a left arrow button in a few situations.
5 Front Panel LEDs Table 5-1 Front Panel LEDs Indication Description Test Test In Progress LED Off No tests are in progress. Solid Red A test condition exists. Data Port LEDs TD Data DTE Activity LED. Represents pulses to DTE. Green Pulses are being detected. Off No pulses are being detected. RD Date DTE Activity LED. Represents pulses from DTE. Green Pulses are being detected. Off No Pulses are being detected.

Flashing Yellow Receiving yellow/AIS alarm. Off Network is inactive. Unit LEDs: Status Maj Min Display the status of the DL3800E, and whether the condition is a Major or Minor alarm. When a port’s Active/Restore mode is set to Never Use and its alarm mode is set to Mask, then the port LED will be turned off.
5 This procedure takes the unit out of the Protected Mode (and clears any password that may have been programmed) and sets all parameters to their default settings. To allow you to perform this procedure when the unit is in protected mode, the Protected Mode is ignored in the first sixty seconds after powering up. When in Protected Mode, the TEST MENU does not appear in the Main Menu. POWER UP AND RESET During power up initialization, the unit performs self test and displays a self-test message.

From the Net STATISTICS MENU, press Enter. When you see Net N CV, press Enter again. The first display will read SEC. 455 VALID.8, showing the number of seconds in the current interval, and the number of valid 15 minute intervals since the error counters were last reset.
5 Table 5-3 NET Statistics Items (Continued) Parameter Definition EB/CV An Errored Block (EB) is a block in which one or more bits are in error. The EB if therefore equivalent to the Code Violation (CV) count calculated and displayed in the previous versions of the DL3800E. This count allows a user to monitor the rate of EB faults on a line that is unavailable. EBs are counted in the unavailable state; ES, SES, and BBE are not counted in the unavailable state.
5 TEST MENU The TEST MENU is used to activate network loopbacks and DTE loopbacks. The TEST MENU is only available when the unit is not in the Protected Mode.Tests are performed by selecting a test from the TEST MENU or one of the TEST submenus, and pressing Enter. To end all tests, press the END TEST button combination (UP and DOWN ARROW buttons simultaneously). When a test is selected that could apply to an E1 port, you are asked to specify to which fraction the test should apply.

To access the DTE TESTS MENU from the TEST MENU, press Enter when DTE TESTS appears in the display. When in the DTE TEST MENU, pressing Enter accesses the DTE/NET Loopback. DTE/NET Loopback The DTE/NET LOOPBACK is a bi-directional loopback that loops the received DTE signal back to the DTE and the signal from the E1 Main Board back towards the E1 Main Board.
5 Network Tests (1-8) Three NETWORK TESTS can be performed through this menu: PAYLOAD (PAYLD) LOOPBACK, LINE LOOPBACK and LOCAL LOOPBACK. To access NETWORK TESTS MENU from the TEST MENU, press Enter when NETWORK TESTS MENU for a particular E1 circuit (NET 1 through NET 8) appears in the display. When in a NETWORK TEST MENU, pressing the UP or DOWN ARROWs toggle between the three options, PAYLD, LINE, and LOCAL LOOPBACK.
5 Line Loopback The Lineloopback is used to verify the operation of the E1 network connection (E1 through E8). The line loopback loops the data received from the E1 network back towards the network. The data is regenerated prior to being looped back, however, no additional processing of the data is performed by the DL3800E. This minimizes the impact of the DL3800E unit during this test so that the problems can be isolated.
5 CONFIGURATION MENU The CONFIGURATION MENU is used to back up the database and to view and change the unit and Comm Port Configuration parameters, network interface parameters, and DTE interface parameters. The remote unit configuration may also be viewed and changed. The DL3800E unit configuration can only be changed when the unit is not in the Protected Mode.

6 Payload Loopback and Line Loopback Tests Use the PAYLOAD Loopback and LINE Loopback tests to verify the proper operation of the DL3800E unit and selected E1 networks. Both tests loop the payload data received from the E1 network back to the network. With the PAYLOAD Loopback, the DL3800E unit regenerates the data and inserts a new framing pattern before it loops back the data. This verifies the unit’s E1 framing and the E1 network.
6 accomplished through DTE loopback and a self test. Testing for the proper functioning of the remote DL3800E unit is accomplished by a Line loopback. It is also possible to verify the path from the DTE through the E1 line to the remote-end DL3800E, provided the DTE equipment can generate and detect looped back bit streams. These suggestions can help determine which portion of the network might be at fault. When discovering a failure, check the simple solutions first.
6 Table 6-1 Troubleshooting (2 of 5) Problem Solution The NETWORK E1 port LED’s on the DL3800E unit never illuminate. Make sure the E1 cable from your service provider is connected to the DL3800E. Make sure that the E1 port is set to configuration other than “NEVER USE”. Remove the E1 cable from the affected E1 port, and hardloop the interface by connecting pins 1-3 and 9-11 of the DB-15 port. If the E1 LED lights up, check your E1 cabling, and contact your service provider.
6 Table 6-1 Troubleshooting (3 of 5) Problem Solution The NETWORK E1 LEDs on an DL3800E unit are flashing green. Make sure a valid DTE device is connected to the DL3800E, and is powered on. If no DTE device is connected and the unit is configured for V.35 or RS449, make sure that DTE LOSS is set to None. If the unit is configured for HSSI, check for a valid HSSI signal (TA). If a DTE device is connected, make sure all DTE port LEDs are on.
6 Table 6-1 Troubleshooting (4 of 5) Problem Solution The connected DTE device shows intermittent errors. Run a DTE/NET Loopback to verify the physical connection between the local DTE device and the DL3800E. If errors are reported during this loopback, check the DTE cable. Make sure the DTE device supports the DTE port clocking option. Use SCTE clocking for the DTE device if the application is using V.35, and the DL3800E unit has more than two connected E1 circuits.
6 Table 6-1 Troubleshooting (5 of 5) Problem Solution You cannot access the DL3800E unit from a terminal. The terminal must be running a VT100 or compatible terminal emulation program. Make sure you are using a straight through cable with pin 8 CTS cut at the terminal end. Make sure the Comm Port parameters match the terminal’s, and the DL3800E unit has a unique ID. If the DL3800E unit is in a daisy-chain, you can display a roll call of all unit numbers by pressing Ctrol-x five times.

G Glossary G A ABAM A designation for 22-gauge, 110-ohm, plastic-insulated, twisted-pair Western Electric cable normally used in central offices. AIS (Alarm Indication Signal) An unframed sequence of All Ones normally sent by a DSU/CSU that cannot maintain the required pulse density in AMI mode or sent by a CSU that has a loss of signal condition on its data port. The signal is sent to maintain continuity of transmission and to notify the far-end that a transmission fault exists on the line.
G B B8ZS (Bipolar 8 Zero Substitution) A technique used to accommodate the ones density requirements of T1 transmission. bandwidth The data-carrying capacity of a transmission medium, usually measured in Hertz (Hz), which equals cycles per second. baud A measurement of the signaling speed of a data transmission device. BER See bit error rate. BES (Bursty Errored Seconds) Occurs when a second has 320 or more CRC violations.
G broadband Services or interfaces that operate above the T1 data rate, typically at NxT1, T3, SONET, or ATM speeds. BPV (Bipolar Violation) Occurs when the ones bit is not represented with the opposite signal of the previous ones bit. C CCITT International Telegraph and Telephone Consultative Committee. central office (CO) The phone company switching facility or center; usually a Class 5 end office, at which subscribers' local loops terminate.
G connector A physical interface, such as DB-15 or RS-232-C, typically with male or female components. CPE (Customer Premises Equipment) Equipment that interfaces the telephone network and physically resides at your location. CRC (Cyclic Redundancy Check) An error checking scheme used to check the received data. The CRC bits within the framing are calculated using the contents of the frame. The calculation is performed again when the frame is received and the CRC values are compared.
G data link Any serial data communication transmission path, generally between two adjacent nodes or devices and without any intermediate switching nodes. data link layer In the OSI model, the network processing entity that establishes, maintains and releases data link connections between adjacent elements in the network. DCE (Data Circuit-Terminating Equipment) Equipment that is either a part of the network, an access point to the network, a network node, or equipment at which a network circuit terminates.
G DSU Loopback A DSU loopback is intended to include as much of the customer data communications circuitry in the looped-back path as possible. The signal passes from the remote unit into the local unit as far as the DSU. This test loops the received network signal back to the network. DSU/CSU (Data Service Unit/Channel Service Units) The pair of communications devices that connect an in-house line to an external digital circuit.
G equalization The spacing and operation of amplifiers so that the gain provided by the amplifier, per transmission frequency, coincides with the signal loss at the same frequency; circuitry that compensates for the differences in attenuation at different frequencies. ES (Errored Second) Occurs when a second has one or more OOF events or CRC violations or with one or more BPV or OOF events. ESF (Extended Superframe Format) A new T1 framing standard used in Wide Area Networks (WANs).
G frame relay A high-speed packet switching protocol used for wide area networks (WANs); faster than traditional X.25 networks, because it was designed for today's reliable circuits and performs less rigorous error detection. Frame relay networks use bandwidth only when there is traffic to send. Frame relay does not support voice. framing A technique which separates incoming bits into identifiable groups to enable the receiving device to recognize and reconstruct them.
G LOF (Loss of Frame) Occurs when a received digital signal loses frame synchronization. LOFC (Loss of Frame Count) A count of declared Loss of Frame events (ESF framing only). loopback A diagnostic test in which the transmitted signal is returned to the sending device after passing through a data communications link or network. This allows a technician (or built-in diagnostic circuit) to compare the returned signal with the transmitted signal and get some sense of what's wrong.
G multidrop A communications arrangement where multiple devices share a common transmission channel, though only one may transmit at a time. N NEBS A network Equipment Building Systems requirement. A standard issued by Bellcore that spells out central office standards for grounding, cabling and power. network An interconnection of computer systems, terminals, or data communications facilities.
G polarity Any condition where there are two opposing charges, such as positive and negative. port The physical point of access into a computer, network or other electronic device. protocol A formal set of rules governing the format, timing, sequencing and error control of exchanged messages on a data network. R RD (Receive Data) A data port signal. receiver The receiver synchronizes the framing pattern, separates the frame bits from the payload data and monitors for frame errors in 64 kbps mode.
G RS232-C An EIA specified physical interface, with associated electrical signaling, between data circuit terminating equipment (DCE) and data terminating equipment (DTE). RS449 A common 37-position interface for data terminal equipment and data circuit terminating equipment employing serial binary data interchange. It is a balanced interface, based on unipolar digital signals, depending more on current flow than voltage, therefore supports greater distances than the RS-232 interface.
G SG (Signal Ground) A signal from DTE to DSU/CSU. simplex current One way transmission used by Telco to provide power to repeaters. SLIP (Serial Line IP) A TCP/IP protocol that allows IP packets to be transmitted over a serial link, such as a dial-up or private telephone line. SMDS (Switched Multimegabit Data Service) A fast-packet technology based on the connection-less data networking capability described in the IEEE 802.6 specification. The data format for SMDS is “cell oriented.
G T-Carrier A time-division, multiplexed digital transmission facility, usually operating at an aggregate data rate of 1.544 Mbps. telnet A remote terminal application that enables you to log on to a remote computer on the same IP network. You can work from the PC as if it were a terminal attached by a hard-wired line to the remote computer. The application uses the Telnet Internet protocol. transmitter In 64K mode, the transmitter inserts the frame bit, with a fixed pattern of 101100.
