Table 2-1. Using the Flash-Hook
Calling a second party with an active call:
Flash-hook to place active call on hold and dial new number. Hanging

ing up will terminate both calls.
Conferencing Calls:
With an outgoing call on hold, and a second outgoing call active, flash-
hook to conference calls. Hanging up will transfer second call.
With an incoming call on hold, and outgoing call active, flash-hook to
conference calls. Hanging up will transfer calls.
With two incoming calls (one on hold and one active) flash-hook to con-
ference calls. Hanging up transfers calls.
Answering calls on hold, and holding incoming active calls:
Flash-hook places the incoming call on hold and reconnects to outgoing
call. Hanging up will terminate both calls.
When connecting to a National ISDN 1 switch, call conferencing and call transferring are as-
signed a unique feature identifier number. This number may not be the same in all areas. The
Configuration/WAN/POTS menu contains the feature identifier numbers for conference and
transfer. If these features do not work, contact your ISDN provider. They can determine the
numbers for these features that can then be programmed into the Express 4100/4110.
Customer Premises Wiring
Customer premises wiring requirements for the Express 4100/4110 vary
depending on the application and existing wiring. It may be simpler for
the ISDN provider to deliver another line to your location. This would
eliminate the need to modify existing wiring. Figures 2-1 and 2-2 illus-
trate two wiring scheme possibilities.
