Appendix A – General information for the United Kingdom
2 Program Incoming ART
The row of the matrix associated with ART = 1, must be defined.
Programming implies entering a list of outgoing ARTs to which
connections are to be denied.
In this case, to bar PSTN to PSTN connections, the ART 1 must be
included in the list of denied outgoing ARTs. The following table reflects
the desired result.

The following sequence is required in Overlay 56:
REQ CHG
TYPE TBAR
ART 1
DENY xx 1 yy zz..<CR> (ARTs blocked outgoing)
Note: If different barring restrictions are required for different types of
PSTN routes, for example CO and DID, then a more complex use of the
feature would be needed.
In order to meet the regulatory requirements of the UK, certain configuration
data must always be set to predefined values.
