Things a Service Technician Can Change
Sending Reliably vs. Sending More Cheaply
Your machine uses one of two methods for correcting errors in transmission
due to bad lines: Error Correction Mode (ECM) or Page Retransmission. Page
Retransmission does not work with Immediate Transmission but ECM does.
ECM is turned on at the factory.
ECM is more efficient, because it only resends the damaged parts of the
transmission, but the number of retransmission attempts is much higher. If you
wish reliable communication and do not mind paying extra communication
charges when you get a poor line, keep ECM switched on.
Pages can be sent up to 3 times before the machine gives up. If you wish to
change the number of retries, contact a service technician.
Protection Against Wrong Connections
This feature prevents accidentally connecting you to the wrong fax terminal.
However, it does not help you if you dialed the wrong number yourself. Also,
you will be unable to send messages to a phone number that forwards the
connection elsewhere.
Your machine compares the number that you dialed with the identification
received from the other end. This identification (called a CSI, see page 146 )
corresponds to the other party’s fax number as they’ve stored in in their
machine. Only the last 8 digits are checked, spaces and pauses in the
telephone number are ignored. If the CSI is not the same as the telephone
number, the transmission is stopped.
Note:lf you cannot send a message to a certain location using this feature,
contact the other end and make sure that they have stored the phone
number identification (the CSI) correctly.
This feature has to be switched on by a service technician.
