Note: All 965DSP Series Loop Analyzers are
equipped with the ISDN Datalink function; however,
this menu item is suppressed in countries where
ISDN interoperability with the 965DSP has not been
verified. Units equipped with the /ADSL option will
display the ADSL modem function. Units equipped
with the /SA option will display the DSL Loss, DSL
Noise, and Spectrum Analyzer functions.
ISDN Datalink (supported countries only)
The 965DSP has an integrated 2BIQ Echo
Canceling Adaptively Equalized ISDN transceiver
which conforms to the ANSI T1.601 standard.
2B1Q ISDN is sometimes called “National
Implementation” or “NI1” ISDN in North American
countries. It is sometimes called “Euro-ISDN” in
Europe and other countries.
Note: The 965DSP will not detect older ISDN
formats (such as ATT AMI, NT AMI, etc.).
