IOLINK-520 & IOLINK-PRO Installation & Applications Guide — 2.17
The following steps must be performed to configure the IOLINK-520 & IOLINK-PRO:
The default switch type for ISDN S/T interface modules is NET3, the default switch type
for ISDN U interface modules is NI-1. If the type of service your provider uses matches the
default setting for the interface module, the following step may be skipped, otherwise, the
switch type must be set.

Switch Type
Ten ISDN switch types are available: net3, ni-1, ni-2, dms-100, 5ess-pp,
5ess-mp, tph1962, kdd, sweden, or ntt. Note that if your routers are
located within different ISDN jurisdictions, the ISDN switch type may
be different on each of the units.

Directory Number

SPID
The directory number will be the ISDN phone number used to establish
a call between the routers. The SPID is used to register the ISDN
interface with the central switch.
For switch type NET3, only one directory number is required. The IOLINK router will
operate without putting in the directory number for a NET3 switch, but it is
recommended that it be entered.
Most North American installations use the switch type NI-1 and must have the
directory number entered, as well the SPID (Service Profile Identifiers) value. For an
NI-1 switch type, enter only the local portion of the directory number unless the area
code is required for local calls. The SPID must be set to the exact number given by
the ISDN service provider.
