Configuring an ISDN Numbering Plan
The ISDN Numbering Plan button in the Protocol Configuration window opens the PRI
ISDN Numbering Plan dialog box. This function allows you to select how the system
will identify and code the Called Number for six different types of calls. This coding
instructs the CO on how to interpret the number being sent to it.
Figure 15. PRI ISDN Numbering Plan dialog box
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, for example,
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
