  • Page 25: Chapter 1 Understanding Isdn And The Isu 512E

    The ADTRAN ISDN Service Unit (ISU™) 512e is a standalone device that connects data terminal equipment (DTE) to the ISDN network. The ISU 512e is specifically designed as a low-cost solution for appli- cations such as video-conferencing, T1 backup, LAN/WAN connec- tivity, and high-speed file transfer.
  • Page 26 T1 circuit. Since ISDN is a switched digital service, bandwidth can be established and utilized on an as needed basis. Therefore, the ISU 512e is well suit- ed for applications where a high bandwidth connection is needed to support bursty or infrequent traffic like medical image or large file transfer.

  • Page 28 Chapter 1. Understanding ISDN and the ISU 512e necessary for operation of the ISU 512e; however, it is useful in trou- bleshooting a misconfigured ISDN line. In some areas, ISDN tariffs may warrant the use of ordering codes with less features. For example, in a particular region, there may be additional monthly expense asso- ciated with having voice service on each B channel.

  • Page 29: Chapter 2 Installation

    NETWORK CONNECTION The ISU 512e supports either dial or leased operation. Four 8-pin RJ-45 modular jacks on the rear panel of the ISU 512e allow connection to the network service. (See Figure 2-1.) Figure 2-1. ISU 512e Rear Panel Dial operation uses the ISDN Basic Rate interface and allows the ISU 512e to dial out over the ISDN network.

  • Page 30: Dte Data Connection

    DTE DATA CONNECTION Data terminal equipment (DTE) is connected to the ISU 512e by using the V.35 interface on the rear panel of the ISU 512e. The maximum ca- ble length recommended is 150 feet for the V.35 interface. The pin as- signments for the V.35 interface are shown in Appendix A Pinouts on...

    EIA-366 connector, see Appendix A Pinouts on page A-1. Smart Dial String Formats The ISU 512e can accept changes to C and C HANNEL using suffix commands appended to the end of the dial string. The fol- lowing string format is used.

  • Page 32: Software Update

    HANNELS If no suffix is used, the call is placed using the values configured for the ISU 512e. For example, if the ISU 512e is configured for 384K, the dial string 7082906055 is the same as 7082906055#4#6. If the C suffix is used, the C suffix is required.
