Chapter 3. Using the Express Configuration Program
61203153L2-20 Express 3000 User Manual 3-9
In regions in which the area code has recently changed, the ISDN
line may be configured with a new area code. ADTRAN’s Au-
toSPID algorithm attempts to recognize these regions and adjust
the area code automatically if AutoSPID initially fails. A table of
old area codes and the corresponding new area codes is located in
the installation directory. This is a standard text file and may be
modified. For Windows 95 and Windows NT 4.0, the default in-
stallation directory is C:\Program Files\Adtran\Isdn.
Phone Numbers 1and 2
Defines the ISDN LDNs. The LDN is the seven digit telephone
number assigned to the ISDN line and is used when placing or re-
ceiving calls. A multipoint line may have LDNs that resemble the
following:
ISDN Phone Number 1: 5551212
ISDN Phone Number 2: 5551213
SPIDs 1and 2
Identifies the ISDN terminal equipment to the ISDN switch. SPIDs
are assigned by the telephone company when the ISDN line is in-
stalled. The SPID usually looks similar to the telephone number.
For example, a multipoint line may have SPIDs that look as follows:
Service Profile ID 1: 0155512120
Service Profile ID 2: 0155512130
The number of SPIDs required (0, 1, or 2) depends on how the
ISDN line is configured. For example, a point-to-point line has no
SPIDs. Multipoint lines have one or more SPIDs. The Express 3000
uses the presence of one SPID to determine if the line is multi-
point. If the line only has one SPID, then the SPID must be entered
in the box labeled Service Profile ID 1.

Disables the automatic detection of SPIDs.
NI1 Conference Feature
Defines the activator code for Call Conference. This code is gener-
ally used only with National ISDN and DMS-100 switches. The
default value is 60.
