Feature description

The AC15 Recall: Transfer from Meridian 1 (ACRL) allows the system
to function as a "recall originating node" in situations where the Norstar
functions as a control node. This capability permits signaling over AC15
trunks, which minimizes the number of AC15 circuits, optimizes the use of
AC15 TIE trunks and avoids tromboning connections.

When a call with a party on the Norstar is transferred from the system, the
ACRL feature enables the system to send a recall signal to the Norstar. This
recall message permits the re-use of the same AC15 circuit, on which the
call was received, to transfer the call. When a transfer is completed, the
AC15 trunk is released. The following scenario demonstrates the ACRL
feature capabilities.

A call occurs between party X (external call) and party Z (on the system).
Party Z initiates the transfer feature and a recall signal is sent over the AC15
trunk. This signal is detected by the control node which puts the calling party
X on hold and provides a dial tone to party Z to invoke a call transfer. The
transfer dialed digits are sent on the AC15 trunk to the control node. A new
