. When this happens, the
program will continue to work normally, but stations at the other end will
probably hear drop-outs or gaps in the audio. The indicator will disappear once
sufficient bandwidth is restored. EchoLink includes a feature that displays a warning indicator whenever the available Internet bandwidth is not sufficient to handle the rate of data being sent by EchoLink. Typically, this can occur when Conferencing is enabled, and the Internet connection does not have enough capacity to support the number of conferencees who are connected. This can easily occur over a dial-up connection if two or more stations have joined the conference. (For this reason, enabling Conferencing is not recommended for EchoLink stations on a dial-up connection.)
Remember that for each station joining a conference, the station hosting the conference needs an additional 17 kbps of upstream Internet bandwidth. If two stations have joined the conference, each transmission from the host station must be sent to both conferencees, requiring a minimum of 34 kbps.
This is rarely a problem with any modern Internet connection, which typically supports a minimum of 128 kbps upstream, and quite often many times that amount.
A "low bandwidth indicator" will appear in the bottom
right-hand corner of the screen when insufficient Internet bandwidth is
available. The indicator is a yellow triangle with an exclamation mark: . When this happens, the
program will continue to work normally, but stations at the other end will
probably hear drop-outs or gaps in the audio. The indicator will disappear once
sufficient bandwidth is restored.
