  • Self Test At power-up, the D-SERV DSU/CSU runs a complete self test routine that checks all the data paths, I/O ports, read/write memory, and the program checksum. At the end of the self test the LEDs will flash in sequence. If the POWER/FAIL LED lights red after self test, this indicates a failed test by the equipment or the power supply. If the POWER/FAIL LED lights green after self test,

  • Jumper Location and Access The configuration jumpers are located on the D-SERV card. Plug-in units have the jumpers readily accessible. To access the jumpers on a stand-alone unit: ¤ Disconnect all power connections and interface cables ¤ Turn the D-SERV unit over, and using a phillips screwdriver remove the four screws connecting the two sides of the case (see Figu

  • ADC Kentrox 78220, Site Selection Use the following guidelines in selecting a site: ¤ (110 VAC only) The installation site should include a grounded 110 VAC power receptacle. ¤ The standard specifications for the following cable distances as prescribed by the standards documents are: Interface Suggested Maximum Cable Length V.35 50 FEET EIA-530 200 FEET NOTE: At lower than maximum speed with proper cabling, longer distances can be achieved.

  • ADC Kentrox 78220, Line Build Out (LBO) Switches The setting for Line Build Out (LBO) to the network is determined by the carrier and is based on the line distance to the nearest T1 repeater. The different LBO settings allow the user to adjust the attenuation of the signal transmitted out the network port of the D-SERV DSU/CSU. The default setting is 0.0 dB. Your T1 service provider will be able to tell you if a non-default setting is required in your application. WARNING: Improper setting of the LBO switches may cause interference with other telephone company ser

  • ADC Kentrox 78220, Switch S3 — Network Interface Clock Source The D-SERV DSU/CSU can derive the Network Interface 1.544 MHz clock in one of three ways. LOOP derives the clock from the network input. INT derives the clock from a crystal internal to the D-SERV DSU/CSU. DP derives the 1.544 MHz clock from the data port (tail circuit timing application). When the data port is configured as the clock source (tail circuit timing) the data port input clock rate must match the data port bit rate set with the DIP switches on S2. Selecting DP clo

  • ADC Kentrox 78220, Electrical Installation CAUTION: Always disconnect all telephone lines before servicing or disassembling this equipment. The power connection with frame ground should be the first electrical connection connected when installing D-SERV units, and the last electrical connection disconnected when removing D-SERV units. Stand-Alone AC Power Connection Plug the power cord on the D-SERV unit into a grounded 115 VAC power receptacle. As soon as power is applied to the D-SERV DSU/CSU the unit will commence self test. Stand-Alone DC Power Connections Use a power supply capable of providing a voltage

  • ADC Kentrox 78220, Features The D-SERV DSU/CSU is available with the following features: ¤ DIP switch selectable configuration ¤ Choice of V.35 Data Port or EIA-530 Data Port ¤ Choice of an internal -24 to -48 VDC or 110 VAC power supply ¤ Normally Open or Normally Closed Alarm Relay contacts (DC versions only) ¤ Diagnostics through front panel switch controlled loop backs ¤ Remote report and alarm retrieval from a DataSMART unit ¤ Remote diagnostics capability from a DataSMART unit ¤ Data Port Timing ¤ Front Panel Status and Alarm LEDs ¤ RJ48C Network interface conne

  • ADC Kentrox 78220, REGULATORY INFORMATION ADC Kentrox D-SERV units have been tested by a Nationally Recognized Testing Laboratory (NRTL) and are in compliance with Underwriters Laboratories (UL) standard 1459, Edition 2.

  • ADC Kentrox 78220, Switch S4 — Alternating and Contiguous Channels The D-SERV DSU/CSU can be configured to activate channels sequentially (contiguous) or configured to activate every other channel (alternating). For example, if four channels have been activated and the starting channel is channel 16, contiguous configuration will activate channels 16, 17, 18, and 19. Alternating configuration will activate channels 16, 18, 20, and 22. Alternating channels is useful to preserve T1 pulse density if large amounts of zeros are to be transmitted as data. Switch S4-4 selects the alternating or contiguous channel option. NOTE: It is not allowed to activate more channels than can be accommodated between the start
