Vocoder Type Drop Down Menu
The Vocoder Type drop down menu, shown in Figure 96, indicates the bit rate at which audio is converted into digital format.
This feature is used to configure communication between the IP-223 and C-Soft.
Available selections for this field are: ADPCM (Adaptive Differential Pulse Code Modulation) 16K and ADPCM 32K.
NOTE: Design considerations must take into account that although 16K requires less bandwidth, the audio quality might
not perform as desired.
IMPORTANT: Vocoder configurations must be the same across devices and C-Soft.
NOTE: When Tape 1 is enabled, a separate stream is created with both RX and TX audio for that line. When Tape 2 is
enabled, a separate Ethernet stream is created with both RX and TX audio for that line. This stream can then be
recorded by a Telex Network Recorder.
Line Name Field
The Line Name field is used to assign a unique label to the tape line.
Mcast Address Field
The Mcast Address field is used to configure the Mulitcast Address used to generate multicast audio for the recorder.
Port Field
The Port field is used to configure the port used to generate multicast audio for the recorder.
TTL Field
The TTL (Time To Line) field identifies the number of routers the multicast audio packets pass through before being
discarded.
Submit Button
The Submit button, located at the bottom of each configuration window, is used to upload changes to the IP-223.
IMPORTANT: The submit button saves changes in temporary memory only.
