| Signalling requirements to support the International Emergency Preference Scheme (IEPS) |

This Supplement is an information document intended to identify the signalling requirements required to support the International Emergency Preference Scheme (IEPS). IEPS is described in ITU-T Rec.

IEPS capabilities provide authorized users with preferential call and connection handling. |
