Connecting a printer for printing connection charges ¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢¢
To print out connection records, the printer
must be on all the time and must be con-
nected to the telephone system. The tel-
ephone system stores at least 500 connec-
tion records and the total connection
charges, even in the event of a power fail-
ure.
Remove the printer cable from the system
when no printer is connected. Close the
housing.
You can connect any printer to the tel-
ephone system’s RS 232C interface to print
out connection records. For connection, you
need a cable that corresponds to the pin as-
signments given below (maximum length 3
m).
Your printer must be set as follows:
- 9600 baud
- 8 bits
- 1 stop bit
- no parity

Hook the four top cover tabs into the cover
latch of the bottom housing half.
Press onto the bottom edge of the cover un-
til it engages.
The ventilation slots on the housing must
not be concealed. Make sure that air circula-
tion is not impeded.
