1. GSM 13Kbps
- Suitable for voice communications only. Should not be used if any tone
signaling is required. Offers the greatest compression with reasonable voice quality.
2. ADPCM 16Kbps
– Suitable for voice or tone signaling. Offers good voice compression, but
the voice quality is lower than the other compression methods.
3. ADPCM 24Kbps
– Suitable for voice or tone signaling. Offers less compression than ADPCM
16Kbps but the voice quality is higher.
4. ADPCM 32Kbps
– Suitable for voice or tone signaling. Offers still less compression, but the
voice quality is the best of the ADPCM compression types.
5. PCM 64Kbps
– Suitable for voice or tone signaling. Offers the highest audio quality of all
compression methods, but provides the least compression. This is the default setting.
You may select a compression method with the VOCODER command followed by the number
of the compression method (1-5). For most applications you may leave this at the default setting.

Security Settings
The NXU-2B may be configured, monitored, and controlled remotely via its network interface
using a web browser or a telnet client. In some instances, it may be desirable to limit access via
one or both of these methods, or to selectively limit the things that may be done remotely. The
SECURITY command allows various levels of security to be set in order to limit remote access.
Additionally, a password may be assigned to limit access via a web browser. Refer to the chapter
on Security for detailed information on setting the NXU-2B security parameters.
3.4.16
Ethernet MAC Address
The Ethernet MAC address of the NXU-2B may be read using the MAC command. When MAC
is typed the 48-bit Ethernet MAC address will be printed as a sequence of two-digit hexadecimal
numbers separated by dashes. No two NXU-2B units have the same MAC address, so this may
be used as an electronic serial number if desired. It cannot be changed by the user.
3.4.17
Command Port
The port used by the NXU-2B for receiving commands via the telnet protocol or from a WAIS
Controller. The value defaults to 23 and under normal circumstances should not need to be
changed. If necessary, the command port may be changed by using the CMDPORT command.
Type CMDPORT <port number> and press ENTER. The port number must range from 1 to
65535 and must be different than the VoIP port.
3.4.18
RX Input Level
The expected RX input level in dBm.
3.4.19
TX Output Level
The desired TX output level in dBm. Assumes the RX level is set correctly on the remote unit.
