Phone
Places a call to a standard telephone. DSP hybrid technology prevents send audio
coloration due to leakage, however the audio quality will still be only 300 to 3.3 kHz
telephone quality. If the ISDN interface and line are present at the time of bootup,
the call will go over ISDN. Otherwise, the call will be placed over the POTS interface.
h HOT TIP!
You can use this mode to call the on-air telephone system of any radio station, or to a
telephone.
Zephyr
NOTE: This option will only be present if the optional ISDN interface is present and
your unit is connected to ISDN.
Places a data call using the ISDN interface to a Zephyr Xstream at the far end. This
mode is only available if the ISDN interface is present. This mode offers very high
quality with very low delay, and is recommended whenever ISDN is available at the
remote site where the Xport will be used.
The Zephyr mode uses AAC-LD - the far end Xstream should be set to:
Xmt = AAC- LD Mono 64, RCV = AAC- LD 64, Sample = 48 kHz.
DROP
The <DROP> key is also straightforward. Pressing <DROP> twice will drop any call
active.
