Appendix F
Ordering ISDN Without IOCs
ISDN is a complex service with multiple options. Obtaining ser-
vice from your local telephone company and long distance pro-
viders can sometimes be complicated. This appendix guides you
and your telephone company in specifying and obtaining your
ISDN service requirements.
To support most of the features in the ISU 2x64, your telephone
service needs to meet certain requirements. A general descrip-
tion of these requirements follows. Depending on your actual
data service needs, some features may be deleted. Other features
may not be available in your area. Also, features may be deleted
for economic reasons, depending on your needs and local tariffs.
Talk to your telephone company first, and find out which of the
services listed on the following pages are provided.
The following form has been designed to assist you. Complete
and FAX this form to your telephone company to request the
proper type of ISDN telephone line for use with the ADTRAN
ISU 2x64.
