In jack is configured to receive a microphone level
(-70 to -40 dBu) or line level (-10 to +4 dBu) audio
input.
3) Mono In Level Control - Adjusts the level of
Mono In audio. These knobs may be extended or
retracted by pressing them in.
4) Local Output - Adjusts the level of locally
produced audio at the headphone jack.
5) Return Output - Adjusts the level of decoded

The Ethernet port on ACCESS 2USB is enabled and
set to DHCP by default.
In order to make a connection on a different
network, an Ethernet or USB network device (Wi-Fi,
4G or POTS) must be installed and enabled on the
ACCESS 2USB. USB devices can be safely installed
or removed when the ACCESS is powered on. IP
network devices must have a valid IP address
before a call can be made.
To enable your network device, go to Network >
Manage Networks on the ACCESS. This list displays
all devices that have been used with the ACCESS.
When you install a compatible device in the ACCESS
by plugging it into one of the USB slots, it will appear
in this list.
To enable the network device, click the desired entry
in the list, and click the Enable button on the right-
hand side. The status message near the bottom
of the screen should change to “Installed and
Enabled”.
As shipped from the factory, ACCESS configures
new network devices for DHCP, which means it will
automatically attempt to obtain an IP address from
your network. When the ACCESS obtains a valid IP
address, the status will show “Current address“,
with the current IP address. If you wish to configure
the device for a static address, select it in the list
and click the Configure button.
On the Locations tab, press Add to create a new
location, select Name and press Edit. Change the
name to something specific and press Save after
each setting change. Select IP Type and press
Edit to change the mode to Static. You will then be
able to edit the IP address, netmask, gateway and
DNS. On the Settings tab, edit the Active Network
Location so it points towards the new location. Press
Apply when done.
Network Device Configuration
At a minimum, ACCESS needs a source of power,
an audio connection and a network or POTS
connection.
The ACCESS 2USB comes equipped with two power
sources: A small external power supply delivers
15VDC from worldwide AC mains, and a Li-Ion
battery pack delivers backup or main power for up
to six hours.
The Mono In and Headphone Out levels are user
adjustable. The Stereo Line In connector has a
nominal level of –10dBu for connection to consumer
level output devices. The Line Out connector has a
nominal level of -10dBu as well.
The Ethernet connector is a standard 10/100Base-T.
A normal Cat5 cable, such as used for a computer,
should be connected here.
The USB POTS modem should be used with a
dedicated analog telephone line.
Setting up the Hardware
Figure 4 - Manage Networks Figure 5 - TCP/IP Configuration

To make an outgoing connection, you must first
create a new remote.
To do so, click Remotes > Add New Remote.
Enter in a remote name for the connection, the IP
Address or phone number of the unit you are calling,
the audio connection password (if any is set) and
choose a profile to use.
To bring up the on-screen keyboard, click the
keyboard icon in the bottom left-hand corner of the
screen. Click it again to remove it.
There are several factory profiles available to use for
your remote. The following are the most commonly
used:
Opus Mono - This is the default choice of profiles
for new remotes. It provides low delay, full duplex,
20KHz mono audio channel over a low (48Kb/s) data
stream.
3G AAC-ELD - This mode is optimized for use over
3G/4G wireless networks like UMTS or LTE. Because
cell networks are asymmetrical (they have higher
download speeds), this profile delivers a robust,
low delay mono stream in the upload direction, and
a low delay, stereo stream in the reverse direction.
This stream can be useful to send separate program
and cueing channels, as an example.
POTS – This profile must be used when dialing a
connection to another codec over POTS
Once you are finished creating your new remote,
click OK. To start the connection, select the remote
from the list and press the Connect button. To
disconnect, simply press the Disconnect button.
