136 AC15 Recall: Transfer from Meridian 1
call to party Y is placed that connects party Z with party Y. A release signal
is sent when party Z completes the transfer and the AC15 trunk is released.
Figure 3 "System to Norstar call transfer" (page 136) illustrates this example.

Operating parameters
AC15 Recall: Transfer from Meridian 1 requires XFEM trunk card NT5K19AC
or later. This feature is only available in countries that use this card type.
There is no signaling capability for the control node to inform the tandem
node or recall originating node that a party has answered or that there has
been a release of any call on a split line.
The recall signal received on an AC15 trunk is not tandemed. No recall
signal is sent on the reception of a "recall" in message.
Unsplitting of lines is not supported. In instances where a line is split, the
line remains split until the whole trunk is released. This parameter ensures
consistency on both sides of the AC15 channel. Additionally, it eliminates
the possibility of selective release of a call in split mode.
The AC15 trunk must be configured with a digitone (CLS = DTN) Class of
Service (LD 14) to ensure that the recall signal is received by the trunk. The
trunk must also be configured on a modified XFEM trunk card.
The far end control node must be a switch that supports the recall signal,
such as a Norstar.
