A description of the most common function keys follows.
Descriptions of the function keys for specific options are
in the section related to each option.
F1—Help
The F1—HELP function key accesses the HELP
information screens. For details, refer to How to get on-
screen Help earlier in this chapter.
F2—B Channel Selection
In BRI mode, the F2—B1/B2/BX
switch between the channels that are available. In NT or
LT mode you can toggle between channels B1 and B2. In
TE mode you can toggle between channels B1, B2 and
Bx.
When you select Bx, an outgoing call may be generated
with a channel ID of ANY. When the first response to the
call setup is received containing a valid B channel, the
system automatically changes to the allocated B-channel
and call processing continues as normal.
When an incoming call requests ANY B-channel, then
aurora allocates the channels from B1. If all channels
Duet
are busy, aurora releases the call with an appropriate
Duet
call clear cause code.
Notes:
• aurora must be set to SLAVE mode before making
Duet
any outgoing Bx (ANY B) channel calls.
• aurora will not execute any AUTO TESTs if the Bx
Duet
channel is selected.
• You can select the Bx channel even if the B1 and B2
channels are busy.
