The NSF Information Element (IE) feature enables system administrators to
coordinate network and service requirements with service providers. Service
providers supply the information that you enter in the
NSF Configuration
dialog box. System administrators can either select any of the pre-configured
NSF settings, or choose to configure their own NSF Information Element using
service provider information.
You can specify the following information in the NSF:
The service providers with which you want their network to work.
The specific network plan and equipment with which you want your
network to work (for example, switches and bandwidth).
The specific services available to their network (for example,1-800
phone numbers).
Instructions are contained in the NSF IE fields of outgoing Q.931 setup
messages in the format shown in
Figure 3-5 .
