    128 Kbps, which is about four times the actual top speed of the fastest analog modems. Compression can increase throughput to around 250 Kbps. DIVA T/A ISDN Modem Reference Guide N Page 4...
  • Page 5 Videoconferencing is an emerging ISDN application that's growing fast in popularity and ISDN is currently the only practical way of making it happen. DIVA T/A ISDN Modem Reference Guide N Page 5...

  • Page 6: Isdn Communication Channels

    Message signaling takes priority over data packet-switching. The D-channel functions at 16 Kbps for Basic Rate Interface or 64 Kbps for Primary Rate Interface. The speed is dependent on the end-user's interface. DIVA T/A ISDN Modem Reference Guide N Page 6 What is ISDN?
  • Page 7 The H-channel is used for high-speed user data traffic at bit rates higher than 64Kbps. Examples of services which require these higher rates are fast facsimile, teleconferencing, and video. An H-channel user can subdivide the channel using TDM to meet specific requirements. DIVA T/A ISDN Modem Reference Guide N Page 7...

  • Page 8: Connecting To Isdn - Bri And Pri

    There is no single transmission rate defined for primary rate access. In North America and Japan, for example, primary rate interface is based upon the T1 rate (defined in detail shortly) of 1.544 Mbps. In Europe, by comparison, the rate is 2.048 Mbps. DIVA T/A ISDN Modem Reference Guide N Page 8...

  • Page 9: What Is Multilink Ppp

    DIVA T/A supports COM port rates of up to 230.4 kbps. However, some computer COM ports are limited to 115.2 kbps. If you want to use your DIV AT/A at its maximum speed, install a “fast COM port” card (UART 16650 based). DIVA T/A ISDN Modem Reference Guide N Page 9...

  • Page 10: What Is Bacp/Bod

    Since BACP/BOD automatically adds and drops the second B-channel in response to traffic peaks and declines, the process is completely transparent. BACP/BOD is an excellent way to reduce communications charges in situations where your demand for ISDN bandwidth fluctuates. DIVA T/A ISDN Modem Reference Guide N Page 10...

  • Page 11: What Is Dba

    DBA with BACP/BOD so that you can have greater flexibility when using the DIVA T/A. Note: If an analog device is used on the server side of the connection, DBA will not restore a channel that has been bumped. DIVA T/A ISDN Modem Reference Guide N Page 11...

  • Page 12: What Is Always On / Dynamic Isdn (Ao/Di)

    D-channel until a B-channel is available, if needed. • As B-channels are invoked only when additional bandwidth is needed, connection costs are significantly reduced. DIVA T/A ISDN Modem Reference Guide N Page 12 What is ISDN?
