Provisioning For U.S. Switches
For the U.S., the Prestige (both the U and S/T interface) has been
approved by Bellcore and has the IOC (ISDN Ordering Code) “S”
Capability, EZ-ISDN 1. Provide this information to your telephone
company when you order your ISDN line. If your telephone company is
not familiar with this IOC, then ask them what kind of switch you will be
connected to and use the information under each switch type to order
your ISDN line.
