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 L128/L128T.

Customer Premises Wiring

Customer premises wiring requirements for the Express L128/L128T 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.
