It is important that the Codec Mode is set correctly (see section 3.1 “Codec Settings”).
From the Top Menu select the CONFigure menu, then select MODE
1= 2 APT ISDN Clr-M
2= 0
À À
Mode configuration
ONE TWO SET EXIT
The top line shows the mode set for channel 1. If a mode is set that can use both channels and channel 2 has not
been set to a different mode, then this is shown by the down arrows.
If channel 2 has been set to an independent mode, then that is shown on line 2.
Use the ONE and TWO keys to select the available modes, or type in the mode number after selecting ONE or
TWO. While the displayed mode is different from the actual mode set, the ‘=‘ is replaced by a ‘:’.
When the required mode(s) is displayed, press ‘SET’.
APTX Modes
If the channel 2 mode has not been set differently, when channel 1 is set to an APTX mode it automatically applies
to channel 2 as well, displayed as “2= 0
À À
“. In this state, the NICA X will frame to an APTX
signal on either channel, or both channels for an IMUX mode.
If channel 1 and channel 2 have been independently set to APTX modes, the APTX codec will be used by the first
channel to connect, and two channel modes will not work.
MPEG Modes
All MPEG or G.722 modes take up a single channel. In a single MPEG unit, or a dual APTX/MPEG unit, the MPEG
and G.722 modes are only available for channel 1. In a dual MPEG unit, they are available independently for the
two channels.
NOTE: The Mode Configuration sets the required Mode. The Mode actually running is displayed in the Top Menu.
Single APTX Version
With the NICA X-1A or NICA X-2A (APTX version) the CH1 mode only needs to be set to the correct APT mode.
APT Modes which are set on CH1 will automatically set CH2 to the same Mode. This allows either ISDN/X21
channel to be used for that Mode. The APT Modes which use IMUX need both ISDN/X21 channels.
Single MPEG Version
With the NICA X-1M or NICA X-2M (MPEG version) the CH1 mode only needs to be set to the correct MPEG/G.722
mode.
Dual APTX and MPEG Version
With this version NICA X it is possible to use the unit in two different styles of Operation.
The two codec cards installed can act as two independent codecs. With the NICA X-2AM (MPEG and APT version)
it is possible to set the Channel 1 Mode to an MPEG/G.722 mode and set the Channel 2 to an APT Mode. For
example:
1= 11 G722 ISDN-M
2= 2 APT ISDN Clr-M
Mode configuration
ONE TWO SET EXIT
In this case the CH1 audio input and output are for the G.722 Mode and the CH2 audio input and output are for
the APT Mode. Similarly the ISDN calls for the G.722 Mode must be made/received on CH1 and the ISDN calls for
the APT Mode must be made/received on CH2.
The second style of operation is where the unit appears as one codec capable of all coding Modes APT, G.722, and
