When connecting to a National ISDN 1 switch, call conferencing and call transferring
are assigned 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 pro-
grammed into the Express XL/XLT.
Customer Premises Wiring
Customer premises wiring requirements for the Express XL/XLT vary de-
pending 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 illustrate two wiring
scheme possibilities.
