Customer Premises Wiring

Customer premises wiring requirements for the Express L128T S/T
vary depending on the application and existing wiring. It may be sim-
pler for the ISDN provider to deliver another line to your location.
This would eliminate the need to modify existing wiring. Figures 2-1
on page 2-4 and 2-2 on page 2-5 illustrate two wiring scheme possibil-
ities.
