Provisioning requirements for North America
If your telephone company is not familiar with Bellcore IOC-S or Easy ISDN-1
parameters, then ask an ISDN representative which switch type will be used to provide
ISDN server to your location and provide them the information under appropriate switch
type heading below to order your ISDN line.
Note: IOC-S and Easy ISDN-1 capability packages will not enable any Supplementary
Voice Service features. You must ask your ISDN service provider to enable them for
you. See "Special note for Supplementary Voice Services" at the end of this chapter for
more details.
