Examples of User Facilities

The following are examples of User Facilities and their corresponding codes.

An Example of a Non-CCITT Facility

The DATAPAC Traffic Class Facility is an example of a non-CCITT Facility.

One of its significant aspects is that it is compulsory when making an

international call. Its coding is 1,1 and it must be preceded by the National

Facility Marker (0,0). For example:

Other networks also define their own Facilities. If you receive repeated “Invalid

Facility Request” messages or if you want to find out more about the Facilities

applicable to you, contact your network representative.
