In the U.S. and Canada, set the SPIDs and directory numbers (DNs) (if 
assigned by the telephone company) for each channel using:
SETDefault !3 -PATH SPIDdn1 “<string>”
DNs may be required for some DMS 100 or NI1 switches. When 
specifying both a SPID and a DN, enter the SPID, then a semicolon (;), 
then the DN.
If you have a second SPID or DN, use:
SETDefault !3 -PATH SPIDdn2 “<string>”
Set the local telephone number for each B channel using:
SETDefault !3.1 -PATH LocalDialNo = “<string>”
SETDefault !3.2 -PATH LocalDialNo = “<string>”
If you have only one local telephone number, enter the same number for 
both channels.
If you are planning to use channel B2 as a separate line, and your 
telecommunications carrier provided only one telephone number for all 
channels, specify a subaddress using:
SETDefault !3.2 -PATH LocalSubAddr = “<string>”
Enable both channels to make sure all settings take effect by entering:
SETDefault !3.1 -PATH CONTrol = Enabled
SETDefault !3.2 -PATH CONTrol = Enabled
Placing a Data Over
Voice Call
In many areas, voice calls over ISDN are charged at a lower rate than data 
calls. You can specify that calls to a given number be established as voice 
calls. This feature is sometimes referred to as a TollSaver capability. 
Telephone companies often refer to this type of call as Switched 56
