Configuring for Your ISDN Switch
Regardless of the operating system or application you are using, the installation process will
request information from you about the ISDN switch and your remote connection. Use the
following information as a reference while configuring your software.
ISDN Switch Type
If you are not sure which switch type you are using, check with your ISDN provider.
Codec
Telephone companies use Codecs to convert signals transmitted over their networks.
Telephone service providers that adhere to U.S. telecommunications standards use u-law.
Many European and Asian telephone companies adhere to A-Law. Check with your ISDN
provider if you are unsure which value to select.
Standby Time
Standby time is a timer which buffers any keypad’s input from an analog device before
sending a message out. In general, this value will not need to be changed from the default
value.
SPID
Certain U.S. ISDN switch types require SPID (Service Profile ID) information be configured in
your software. If required, your telephone company will provide the necessary SPID values.
SPID1 refers to the first ISDN line. SPID2 refers to the second ISDN line.
MSN (POTS)
MSN (Multiple Subscriber Number) is a supplementary service generally used by European
ISDN switches. MSN service provides the possibility of assigning multiple ISDN numbers to
a single interface. The POTS field is used to enter the phone number associated with a
voice line. In a two channel ISDN configuration, if the MSN (POTS) field is left blank, either
number can ring. If a phone number is entered, the number dialed on the incoming call must
match the MSN (POTS) value for the analog device connected to the POTS (voice) (a/b) port
to be enabled.
SAD
SAD (Sub addressing) is used by certain European ISDN providers. If subaddresses are
available in your area enter the phone number in the format, 7706043*1, where 7706043 is
the called (remote) phone number and 1 is the subaddress. The phone number and
subaddress are separated by *.
Protocol
In some configurations, you will need to select HDLC, X.75 Transparent, V.120 or Auto-
Detection as your incoming protocol. The incoming protocol selection is based upon the
protocol of your ISDN adapter. The outgoing protocol selection is based upon the protocol of
the remote ISDN device to which you are connecting.
