Frame Relay

Frame Relay services are based on Broadband ISDN. The system supports very basic frames consisting of a logical channel address known as a DLCI.(Data Link Connection Identifier). Frame handlers switch the logical channels based on switching tables populated through signalling or network management functions. Frames are variable in length with the maximum payload of 4,096 octets.
