Note:
SITE
refers to a single V2015A matrix switching bay in a
V2015A network and the resources that are directly connected and
accessible to it.
Receiver/Sending SITE
- a network site which sends and receives
video trunk signals.
Video trunks carry video signals between each Receiver/Source
V2015A site.
SITE-to-SITE Video Trunk Considerations
A typical SITE-to-SITE two-way video connection requires one or
more source trunks and receive trunks between each
receiver/Sending SITE. The number of trunks used between sites
will depend on the user's application and requirements.
z
Determine the number of video trunks required between all sites
in the network prior to installing the trunks.
z
Determine the maximum number of different video inputs from
each Sending SITE to each receiving site and reserve one video
input terminal at each receiving site for each video trunk input.
z
Determine the maximum number of video trunk outputs from
each Sending SITE to each receiving site and reserve one
monitor output terminal at each Sending SITE for each video
trunk output.

Figure 2-24. Two-way Network Video Trunk Connections
2.4.11.4 Mixed Network Connection
A mixed direction network consists of both one-way V2015A sites
and two way V2015A sites.
A mixed direction network between three or more sites requires one
or more video trunks for each Sending SITE or receive site and one
or more receive trunks and source trunks between each
receiver/Sending SITE.
Note: SITE
refers to a single V2015A matrix switching bay in a
V2015A network and the resources that are directly connected and
accessible to it.
Sending SITE
- a network site which sends video trunk outputs to
other sites.
Receiving SITE
- a network site which receives video trunk inputs
from other sites.
Receiver/Sending SITE
- a network site which sends and receives
video trunk signals.
Video trunks carry video signals between V2015A sites.
SITE-to-SITE Video Trunk Considerations
A typical SITE-to-SITE mixed direction video connection will
consist of source only sites, receive only sites and receiver/Sending
SITEs. The number of trunks used between sites will depend on the
user's application and requirements.
z
Determine the number of video trunks required between all sites
in the network prior to installing the trunks.
z
Determine the maximum number of different video inputs from
each Sending SITE to each receiving site and reserve one video
input terminal at each receiving site for each video trunk input.
z
Determine the maximum number of video trunk outputs from
each Sending SITE to each receiving site and reserve one
monitor output terminal at each Sending SITE for each video
trunk output.
