Data Communications
In addition to voice communications capabilities, the system also supports data
and video communications to enable users to send or receive data, or establish
group or personal video conferences.
NOTE:NOTE:NOTE:
To configure the switch to support data communications across a private
network, see the
Network Reference
for information.
Planning for data and video communications consists of the following tasks:
1. Planning how the data and/or video equipment connects to extension jacks
on the control unit. This depends on the type of data stations or video
systems.
2. Creating modem/ISDN terminal adapter pools (pairs of modems and ISDN
terminal adapters) to enable calls between the two types of data stations:
modem data stations and ISDN terminal adapter data stations.
3. Assigning lines/trunks to data stations and video systems.
4. Assigning features to data stations.
5. Creating data hunt groups (DHGs), that is, data calling groups, if there are
modem/ISDN terminal adapter pools with more than one data
communications equipment pair (a modem and an ISDN terminal adapter),
or to designate a group of either modems or ISDN terminal adapters to
receive calls to communicate with a local host computer or local area
network (LAN) workstation.
NOTE:
Modem/ISDN terminal adapter pools are not described in this book.
