Leaf Initiated Join (LIJ) is a service feature ofATM networks
. The LIJ service feature can be used to extend an existing connection
between end nodes by another end node. This LIJ procedure is triggered by a Leaf Setup Request (LSR) from the new end node to the ATM network. The network responds with an acknowledgement in the form of a setup to the new subscriber. The new subscriber then sends the connect to the network, whereupon the new subscriber is announced to the sending end subscriber with a New Leaf Announce.
