I Applications
Videoconferencing
Considerations and Constraints
Generally, video workstations should have exclusive use of their own lines and
dedicated pools (Hybrid/PBX mode only). Because they require two lines for
optimal performance, sharing lines is often not practical. Pools should be
assigned only lines that provide like services (for video systems, T1 data-only, or
PRI and BRI voice and data). ARS should also be programmed so that extensions
access pools with the proper grouped facilities (T1 or analog voice only, T1 data
only, or PRI/BRI voice and data). ARS default local and toll tables should be
programmed to route calls according to their type: voice only, data only, or both
voice and data. For more information, see
77, "Basic Rate Interface (BRI)" on page
and T1" on page
Feature Interactions
Features that redirect the destination of a call (for example, Coverage features
and Forwarding) are not often practical for extensions used by videoconferencing
systems. For example, if a video system is a coverage sender, a receiving video
system can be assigned only one Cover button for the sender. Therefore, it
cannot receive both calls of a 2B video call.
Data hunt groups are not practical where 2B data is required, because two calls
must arrive at the destination video system, and data hunt groups distribute the
two calls that make up a 2B data call to two different data hunt group members.
The following list details specific feature interactions. For additional information,

Account Code Entry can be entered for calls made by video systems that
support the use of # for feature codes. The account code must be entered
before the telephone number.
Authorization codes can be used by video systems that support the use of
# for feature codes.
A video system that supports the use of entering # for feature codes can
use Auto Dial in the same fashion.
Video calls can be made using ARS. To make calls using ARS, video
systems simply dial the ARS dial-out code (usually 9) followed by the
telephone number. The calls must be routed through ARS pools that have
only PRI, NI-1 BRI, and/or Switched 56 T1 data lines. To make a 2B data
call, the user must access two separate lines.
Video calls cannot be barged into.
