■Modem/ISDN Terminal Adapter Pool. A special type of hardware configuration that combines one or more pairs of DCEs to enable communication between modems and ISDN terminal adapter data stations. A pair consists of one modem and one ISDN terminal adapter. Modem/ISDN terminal adapter pools are set up in one of two ways depending on the type of data station being used to send data: analog-to-digital or digital-to-analog. For more information about these pools, see application note, MERLIN LEGEND Communications System Modem Pooling.

■Data Hunt Group (DHG). A data calling group typically used to distribute calls to modem/ISDN terminal adapter pools that have more than one pair of DCEs. For more information about DHGs, see the application note, MERLIN LEGEND Communications System Modem Pooling.

■Video System. Equipment that allows desktop or group video conferencing. This equipment connects either directly or through an ISDN terminal adapter to an MLX jack on the MERLIN LEGEND system. If the MLX port is programmed as a 2B Data port, the video systems can use both of the B-channels assigned to the MLX port to provide video. Many video applications also support data sharing and/or transfer.

NOTE:

If the video system is connected to the MLX jack through an ISDN terminal adapter, unless the ISDN terminal adapter itself supports 2B Data communications, it is recommended that the MLX port not be programmed as a 2B Data port.
