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. Please 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.
