  • Page 4: Overview

    2. Overview 2.1. Introduction RC 903-V35FE1 is an interface converter for V.35 equipment based on E1 network transmission. With growing utilization resources, many data transmission solutions using E1 link are accepted by users. RC 903- V35FE1 is standalone equipment, with built-in power supply, and can be placed on the table.

    When connecting to DTE equipment such as Router through M34 interface, it is suggested to use special DTE cable for Router. When the DTE cable is not long enough, Dynamix can provide CBL-V35-M34F/M34M- D extension cable. When connecting to other DTE equipment through M34 interface, it is suggested to use cross-connect cable CBL-V35-M34M/M34M-X-D provided by Dynamix.

  • Page 20 other manufactures. If Routers with E1 interface are used at remote side, users are required to first confirm all the parameters of E1 link, such as fractional/transparent E1, PCM30/31, CRC enable/disable, clock relations, bandwidth distribution and time slot usage etc. If any one of them does not match the setting of the converter, there will be problems in connection.

  • Page 21: Equipment Installation And Preparation

    5. Equipment installation and Preparation 5.1. Installation preparation Make sure that the E1 line cable matches the equipment model connected to it. The default effective interface is 75Ω BNC. If user wants to use BALANCED interface, please set the 6 group of dip-switches on the bottom.

  • Page 22: Placement

    RLP indicator is on, local Router should indicate successful loop-back. If Dynamix converter does not work in pairs, then it is required to set parameters of E1 interface of other brand equipment consistent with settings of Dynamix local converter.

    6. Troubleshooting If there are any problems during installation and operation, please try to solve them according to the following suggestions. If the problems still exist, please contact distributors for help. Power (PWR): indicator OFF Answer: Please check if there is any fault with power supply. Loss-of-Signal (LOS) alarm in E1 link: indicator ON Answer: LOS alarm caution that your E1 interface cannot receive signal.
