Caller ID Choices for
Analog Lines
When you order analog telephone lines from your telephone service
provider, you can also order caller ID service. Your telephone service
provider can tell you the format in which they provide caller ID
information.
You can configure your NBX system to work with any of these formats:
■
Bellcore GR-30-CORE
■
ETSI FSK
■
ETSI DTMF
■
British Telecom SIN 242
■
NTT Telephone Interface Services
See the NBX Administrator’s Guide for information on how to configure
Analog Line Card ports for the caller ID format you want to use.
