Desktop 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 "Automatic
Route Selection," "Basic Rate
Interface (BRI)," and "Primary
Rate Interface (PRI) and T1."
