APPENDIX C-USING ACCESS ON UNIDIRECTIONAL NETWORKS
Under most circumstances, ACCESS requires an IP path in both directions for successful connections, even when
audio is being sent only one-way. For networks that provide data only in one direction, it is possible to use Standard
RTP mode to establish and maintain these links. This section describes how to set that up.
The following setting applies to both codecs in the link (encoder and decoder):
The codec has several compatibility modes under the Standard RTP channel mode. The units default to a mode that
is compatible with the Luci Live PC-based encoder. This must be changed on both codecs.
1 On the ACCESS Rack, enter the Web-based User Interface and choose the
System Settings
tab.
On the ACCESS 2USB Portable choose Configure > System Settings
2 Find the
Advanced
tick-box and check it
3 Find Standard RTP Settings and choose to edit the RTP Compatibility mode .
4 Change this setting to
Standard
and click
Apply
(or
Save
on ACCESS 2USB Portable).
DECODE SIDE SETTINGS ONLY
Also under Advanced Standard RTP Settings , find the Return Channel Enable entry. Disable the return channel and
click Apply (or Save on ACCESS 2USB Portable). This will make sure that no channel will be set up in the direction to
the encoder.
ENCODE SIDE SETTINGS ONLY
Obviously, connections of this type must be established from the encoding side of the link. So you’ll need to build
a new Profile that uses the
Standard RTP channel mode under the Profile Editor. Choose your outgoing encoder
along with any other special attributes in the profile editor. Name the Profile something descriptive like “Simplex”.
Next, create your outgoing remote entry in the address book. Apply the new profile to that entry. Any connection
made with that entry will connect in a unidirectional fashion.
FULL-TIME OR TRIGGERED CONNECTIONS
A remote entry using a unidirectional profile can still utilize the tools required for automatic connection.
To set up a connection to be “always active” (i.e. reconnect in the case of power outage or network failure), choose
that connection on the
System Settings Tab as the Always Connect To location.
To trigger the connection when an external contact is closed, choose the connection under one of the Contact
Closure settings on the System Settings tab.
