Appendix D   How to Order ISDN BRI
This appendix contains the minimum ISDN BRI specification that the VisuaLink 
can operate.  If you should have any question about the ISDN ordering procedure, 
please call your videoconferencing provider.
The ISDN configuration can be a complicated process.  Things to remember when 
ordering your ISDN.
• The VisuaLink only uses one type of ISDN, BRI.
• The How to configure the ISDN BRI form provides most of the information you  
need to configure your system for ISDN service
How to Configure the ISDN BRI
The key to making configuration as easy as possible is getting the right 
information from your network service provider.  In addition to providing your 
network service provider with the correct your specification.  When ordering your 
ISDN NEC recommends that you go through the following ISDN ordering 
procedure to assure accurate information from your network service provider has 
been received and provided.  
1.  The videoconferencing user fills out the following.  The user then 
forwards this information and the Network provider information to the 
Network provider.
Name:
Title:
Company:

City:
Phone:
Fax:
State/Province:
Zip:
Network Provider
The Site location where the ISDN BRI service will be installed:
Note:
  You will need to plug your videoconferencing system into a device called 
an NT1 before you plug the system into your ISDN BRI wall jack.  This assumes 
that the ISDN BRI service will be coming directly from the Telco and not an in-
house switch (such as NEAX2400 or 2000). You must identify who will be 
providing the NT1.
