Network compatibility
notices
This equipment has been designed, tested, and found to be compliant
with the European technical standard TBR 21 for pan-European
single terminal connection to the Public Switched Telephone Network
(PSTN).
This applies to all X4500 MFP Options which bear the following mark:
This equipment is designed to work with PSTN networks that accept
analog signals.
However, due to differences between the individual PSTNs provided
in different countries, the TBR 21 certification does not, in itself, give
an unconditional assurance of successful operation on every PSTN
network termination point. In the event of problems, you should
contact your equipment supplier.
