Defining RS366 (Video)
Virtual Circuit Templates
Setting up a PRI PBX Tie Line PRI signaling is a type of CCS in which one
channel (24) is used to signal for the other channels (1-23). This is in contrast to
CAS in which signaling is done on all channels.
To set up a PRI PBX tie line, follow these basic steps:
1 Configure the CBR port as follows:
Set the Port Mode to Structured Data.
n
Set the other port parameters as appropriate for your application.
n
2 Configure the CBR circuits as follows:
For channel 24, set the Mode to Normal.
n
For channels 1-23, set the Mode to DBA.
n
Set the other circuit parameters as appropriate for your application.
n
The RS366 video dial feature uses CBR virtual circuits to support dialed video
conferencing over an ATM network. The feature works as follows:
To set up RS366 virtual circuit templates, you follow the same basic procedure
n
that you do to add PVC virtual circuits (see "Adding Virtual Circuits" for
details). The RS-366 (video) templates are identified as such when you select
RS366 Template (rather than PVC) as the VC Type (see step 4 under "Adding
Virtual Circuits"). Before you can make a video call, you must set up an RS366
virtual circuit template.
You can define as many templates as you want to connect to different
n
destinations.
When the phone number associated with a given template is dialed, the
n
PathBuilder S330/S310 software locates the template and uses it to create a
temporary virtual circuit to which it assigns the default description <366 call>.
A video connection is established either via the Manual Connect A Site menu, as
described in "Managing Video Dial-up Sessions" 'later in this chapter, or when
someone dials the phone number associated with the video circuit on a video
keypad.
Data for the video conference is transmitted and received over the
n
newly-created <366 call> circuit.
When the call is disconnected, the system deletes the <366 call> circuit, but
n
preserves the template upon which the circuit was based for future use.
For further details about video conferencing and information on setting up call
routing tables for point-to-point video conferencing (between remote PathBuilder
S330/S310 switches) and multi-point video conferencing (both between remote
PathBuilder switches and between a central PathBuilder S330/S310 and remote
PathBuilder S330/S310 switches) see "Video Conferencing" in Appendix B.
Since only one video virtual circuit is active at any given time, you must build
multiple video-associated virtual circuits—even though they use the same physical
port and T1/E1 channels.
