■ COR/COS
The Class of Restriction and Class of Service for a multimedia call
originated from an Enhanced multimedia complex are those of the voice
station in the complex.
■ Data Call Setup
An Enhanced mode multimedia H.320 DVC system may not originate calls
from the DVC system. All calls, both voice or video are originated from the
voice station.
■ Data Hotline
An Enhanced multimedia complex H.320 DVC endpoint may not be used
to originate a call for hotline dialing. In order to setup a video hotline
function with an Enhanced mode complex, the hotline number
administered for the voice station should include the Multimedia call
feature access code.
■ Data Trunk Groups
Data trunk groups may be used to carry H.320 calls of a fixed
(administered) bearer capability.
■ ISDN Trunk Groups
Lucent Technologies highly recommends that you use ISDN trunks for
multimedia calls. ISDN PRI trunks allow complete 1-number access for an
Enhanced multimedia complex. ANI provided over PRI trunks allows
correct routing of multiple bearer channels to the correct destination
device. ISDN also provides the bearer capability on a call by call basis that
can be used to distinguish voice calls from multimedia calls.
■ Night Service
Incoming H.320 calls follow established night-service processing for data
calls.
■ Remote Access
The switch does not prevent Enhanced multimedia complexes from
attempting to use remote access. However, these endpoints will most likely
not be able to dial the necessary codes.
■ Station Hunting
Multimedia calls to Enhanced mode complex voice stations that have an
extension administered in the hunt-to-station field hunt based on
established hunting criteria. If the hunt-to-station is also an Enhanced mode
complex station, a multimedia call will result when the call is answered.
