Decoder Mute
It may sometimes be necessary to mute the decoder (incoming audio).
This may be necessary if a far-end user does not have mix-minus setup
properly and you hear yourself coming back with an echo.
To mute the decoder, use the DMU command or the sequence
<Advanced><Decoder><Audio Out><Mute>
Speed Dial Table Maintenance
With up to 256 entries, the
RoadRunners
Speed Dial directory is
perhaps the most powerful tool available to a user. The directory is
used to hold Quick Configurations, which only configure the codec,
and Speed Dial entries, which not only configure, but dial up to 2 ISDN
numbers. MUSICAM USA has pre-programmed 45 basic configurations
as well as 4 entries that will dial our 24–hour Music Line test number.
Maintaining the directory, adding entries, editing existing entries and
deleting entries is simple. The RoadRunner even uses ‘system
snapshots’ to create both Quick Configurations and Speed Dial entries.
There are three different ways of creating a table entry: You can use
‘System Snapshots’, edit an existing entry to create a new one, or you
can create an entry manually. Remember that the only difference
between a Quick Configuration and a Speed Dial entry is the presence
of ISDN phone numbers.
Creating Quick Configurations and Speed Dial Entries Using
System Snapshots
Once you have configured the encoder and decoder to your satisfaction,
you can save the configuration for later recall. To automatically create
your own Quick Configuration using the current settings, simply press
the
SDSET
button, and select the
<Save Current>
option. You will be
prompted to enter a descriptive name, up to 15 characters,
spaces are
not permitted
. Characters are entered using multiple presses of the
alphanumeric keypad, using the right-arrow button to advance to the
next character. Terminate the name by pressing the
ENTER
key.
