ISDN Configuration Guide C-3
Example SPIDs
If your ISDN line is controlled by a DMS-100 switch using National
ISDN-1, and your directory numbers are given as (415)234-5678
and (415)234-5679, your SPIDs are 4152345678010 and
4152345679020. Alternately, your SPIDs can be
41523456780100 and 41523456790200.
Second directory number
The Add Connection Profile screen in the WAN Setup (Advanced
Configuration) now contains the item Optional Second Number. This
item should be filled in when the remote network (the network router
being called) has a separate directory number for each B-channel.
Switch-specific uses
In general, if the remote network has an ISDN line with an AT&T
5ESS
switch, only one directory number is needed. However, the
remote network may be set up to require incoming calls to use
separate directory numbers for each B-channel. In this case, enter
the second directory number in the Optional Second Number item.
If the remote network has an ISDN line with a DMS-100 switch and
is not in a hunt group, it should have one directory number for each
B-channel. Both directory numbers are required by the Netopia
Router to make a connection to that network using two B-channels.
In this case, enter the second directory number in the Optional
Second Number item. If only one directory number is available in
this case, only one B-channel can be used when connecting to that
network.
