Zephyr Xmt-To-Rcv Mode Compatibility Table
This table shows which Zephyr Xmt and Rcv modes may operate with each other, the
resulting audio bandwidth for each, and information which describes what happens to
the audio channels when they are output from the decoder.
Xmt Mode
L3 DUAL (one Line)
(Channel A)
L3 DUAL (two Lines
to two sites)
L3 DUAL (two Lines
to one site)
L3 JSTEREO or L3
STEREO
L2 MONO
(Channel A)
L2 MONO128
(Channel A)
L2 JSTEREO
L2 DUAL
L2 HALF/24
G.722
* Depending upon sampling rate: 15kHz at 32 kHz; 20kHz at 48 kHz.
** Depending upon bitrate: 7.8kHz at 56kbps; 9.8kHz at 64kbps.
As well, both transmission bitrate and audio sampling rate must correspond in order for
operation to occur. See below.
