Nortel Networks 555-4001-135, 553-3001-358 manual ICB operation, Ethernet application

Product description 27

Ethernet application

ICB Ethernet use has the following characteristics:

•The ICB Ethernet connection is separated from the external LAN traffic by a firewall.

•The Ethernet Adapter connection for ICB is NT5D52AA for the IPE module application.

•The Ethernet provider assigns the IP address for the ICB. Enter the IP address from the Maintenance terminal.

•To access the ICB CLI over the Ethernet, use a TELNET client on a PC workstation or in the LAN.

ICB operation

The ICB provides flexibility in configuring conferences. Configure conferences as follows:

•pre-scheduled conferences with a fixed number of ports and start/stop times

•pre-scheduled conferences with a variable numbers of ports, where ports are added when required (if available) and subtracted by the system automatically as conferees leave the conference

•permanent bridges with fixed numbers of ports that can be used without pre-scheduling the conference

The minimum duration of a conference is 15 minutes and the maximum duration of a time-limited conference is 12 hours. The conference starting time and duration can be scheduled in increments of 15 minutes.

The ICB card continuously monitors the audio signal level received from each conferee and selects the two loudest signals for transmission. The two loudest signals are summed and inserted into the PCM sample prior to their transmission to other conferees. This implementation of the two loudest signals improves the interrupting capability of a conference connection and allows normal two-way conversation that all conferees can hear.

In addition to the conferee timeslots, the ICB provides a timeslot between the MPU and the DSP. This timeslot transmits message prompts, entry and exit tones, or both that the system broadcasts to all conferees when requested by the MPU.
