Q: Can I make ACCESS maintain an IP connection regardless of net-
work status?
A: Yes. First define your remote setting and apply a profile to it. Next go to
the
System Settings Tab
, and pull down the menu labeled
Always Con-
nect to Remote
. Once you select your remote here, a connection to the
remote will be established and remain indefinitely.
Q: Can I get a remote indication that ACCESS is connected to some-
one?
A: Yes. Using the
System Settings Tab
, you can re-assign
Contact Closure
Output #4
to trigger whenever the ACCESS front panel
Ready
light is lit,
indicating a valid incoming connection. The function of
Contact Closure
#4
will be changed in the following ways:
a)
Contact Closure #4
will no longer be available as an end-to-end
signal.
b) Whenever ACCESS detects a valid incoming stream, it will trigger
CC #4
and maintain it until all valid connections stop.
Q: What steps should I take when I’m having connection problems
with ACCESS?
A: There are several steps you can take to determine that cause of poor
IP connection using ACCESS. The first step is to determine whether the
problem is occurring in one direction or both. If in only one direction,
take a look at network usage patterns on the local end of each ACCESS.
If someone else on your LAN is downloading large files on the decoder
side (or uploading large files on the encoder side) this may cause some
performance issues. You may need to ask them to temporarily cease activ-
ity, or investigate a network router solution that will offer ACCESS priority
over other traffic. Next, take a look at the
Status Tab
on the ACCESS that
is decoding the faulty audio. Take a look at the jitter figure for your incom-
ing connection. If this number is varying dramatically (good networks
keep this figure below 50mS) then you may need to increase the
Local
Delay Cushion
setting within the profile used to connect to that remote.
Although it will increase your audio time delay, you may find increasing
the cushion by 100-300mS or more will result in more stable connections,
since the jitter buffer manager will no longer attempt to reduce delay by
making the buffer smaller than the cushion.
