Testing the ISDN BRI network connection

Before you install a Norstar system which uses BRI cards you
should test your connection to the ISDN network.
If you are installing a system which connects to the network
using BRI-ST cards, the network connection must be equipped
with an NT1. See the ISDN chapter and the wiring information
in this chapter for more information about installing an NT1.
To test the ISDN BRI connection:
1. Connect ISDN terminal equipment (TE) that conforms to
Bellcore standard to your central office ISDN jack or NT1.
U interface TE can connect directly to the central office
jack. S interface TE connect to the central office through
an NT1.
2. Program the TE with the appropriate switch type, service
profile identifier (SPID), and Network directory number
(DN) using the instructions that come with the TE.
3. Check for dial tone, then place a call and verify the quality
and clarity of the connection. If there is a problem, contact
your service provider.
4. Repeat steps one through three for each network
connection.
