Board Configuration
For each class, select the type of number/numbering plan from the drop-
down list:
• Type of Number:
— Unknown
— International
— National
— Network Specific
— Subscriber Number
• Numbering Plan:
— Unknown
—ISDN
— National
—Private
The setting ‘Unknown’ is used when the user or network has no knowledge
of the numbering plan. In this case, the number digits field is organized
according to the network dialing plan.
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 drop-
down list to identify the type of carrier service you wish 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.
