Modem Configuration Screen – DID Modem “Modem Configuration: DID Modem” Screen Field Definitions
Field Name Values Description
Max DID Digits 2-7 The number of digits that the telco supplies to the
DID line when an incoming call is received.
Default = 4.
FAX ID alphanumeric;
20 characters,
max.
The value in this field is usually the phone
number of the line to which the DID modem is
attached. However, any alphanumeric string up
to 20 characters is allowed. Sometimes
company names or abbreviations are included in
this string. This ID number will appear in the
sender’s fax log.
Max Baud Rate 2400 – 33,600 bps The value in this field determines the maximum
baud rate used for fax calls on the DID modem.
It is typically set at less than 33,600 bps only if
there are quality problems with the phone line.
Default = 33,600 bps
Polarity A or B Orientation of DID battery voltage. DID lines are
polarity sensitive. The polarity of the battery
voltage on the DID line is very important for the
DID line to work properly. Since the line comes
from the telcom as an unmarked twisted pair, the
required polarity can only be determined through
trial and error. The modem is set by default to
Polarity A. If an immediate busy signal is
received when a DID number is dialed, or if the
call is dropped shortly after connecting, then the
battery polarity is probably wrong and the
opposite battery voltage polarity should be tried.
Default = A
