ACCESS comes with a series of profiles that are optimized for the majority
of IP and POTS connections. Many users may never have the need to define
their own profiles. But many advanced options are available to help with
troublesome remotes, or remotes with special requirements. In this way,
you can build a profile having these advanced options and assign them to
one or all remotes you’ve defined. When using ACCESS, the point where
the connection originates controls all available connection parameters
in both directions. Keep in mind that these profiles are useful only for
connections initiated from the local ACCESS. Incoming connections are
defined by the ACCESS at the other end.
Several factory profiles are available and may not be edited by the user.
Here’s a short description of the proprietary and less known encoding
profiles:
HQ1 Default
– This is the default choice of profiles for new
remotes. It provides a low delay, full duplex, 15KHz mono audio
channel over a small (28kb/s) data stream.
HQ2 Default
– Although this profile adds substantial additional
delay, it is extremely robust and performs well over connections
that are prone to packet loss. It provides 15KHz two-way mono
audio over small (24kb/s) data streams.
