The PRI ISDN Numbering Plan dialog box displays the six classes of
numbers (call type) that can be sent to a CO:
• 101CCCC Numbers - CIC (Carrier Identification Codes) dialing.
• 011 International Numbers - for placing calls outside the U.S.
• 1+10-digit Numbers - for local and long distance calls that require
dialing 1 before the number.
• 10-digit Numbers - for local and long distance calls that do not
require 1 before dialing.
• 7-digit Numbers - for calls placed within the local area that do not
require an area code or a 1 prefix.
• All Other Numbers - for calls that do not fall into any category
above, i.e. 911, 311.
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.
