Setting the NSF
The NSF (Network-Specific Facilities) is used with PRI to instruct the CO to route a call to a specific carrier
or long distance service. Use the list to identify the type of carrier service you want to use for your ISDN PRI
lines.
The choices in the list depend on the specific switch and your long distance service provider. An example of
such service includes AT&T Megacom.
Note: If your CO requires specific NSF features to be present in the call setup packet, please contact
AltiGen’s Technical Support department with such information from the CO and they will help you
configure it.
Setting a TEI
The TEI (Terminal Endpoint Identifier) defines which terminal device is communicating with the CO switch
for a given message. PRI messages involve point-to-point configuration in which each side already knows the
source of any message received. ISDN messages involve point to multi-point locations in which the source can
only be identified by the TEI.
Select one of the following TEI settings:
• Default setting – This is the recommended setting.
• Manually set to – This should always be set to 0. Typically, a zero (0) is used for TEI on a PRI connection.
In some cases where a shared D channel is used, other TEI values might be required to identify which
span will be used for a call.
• Assigned by CO switch – Do not use this setting unless advised by your CO.
Setting PRI Calling Numbers
A PRI Calling Number Setting in the bottom half of the Protocol Configuration dialog box lets you set the
numbers you want your Carrier to accept.
