Ecm (Error Correction Mode); Multi-Line Connections (Pabx) - Brother MFC-7420 User Manual

Introduction

ECM (Error Correction Mode)

1
The Error Correction Mode (ECM) is a way for
the machine to check a fax transmission
while it is in progress. If the machine detects
errors during fax transmission, it resends the
pages of the fax that had an error. ECM
transmissions are only possible between fax
machines that both have this feature. If they
do, you may send and receive fax messages
that are continuously being checked by the
machine.
If this feature stops working, delete your
faxes from the memory.
Multi-Line connections
(PABX)
Most offices use a central telephone system.
While it is often relatively simple to connect
the fax machine to a key system or a PABX
(Private Automatic Branch Exchange), we
suggest that you contact the company that
installed your telephone system and ask
them to connect the fax machine for you. We
recommend all our fax machines be
connected to a discrete line. Although some
fax machines will work with a particular
PABX, we cannot guarantee that the unit will
operate properly.
If the fax machine is to be connected to a
multi-line system, ask your installer to
connect the unit to the last line on the system.
This prevents the unit from being activated
each time a telephone call is received.
