<h1>Signalling Point Code Modification</h1>

<p>In the current BSS implementation, if the BSS is wanted
to move from an MSC to another MSC, A interface speech circuits, signalling
connection control part (SCCP), and message transfer part (MTP) must first
be deleted. After that all same parts can be created with new signalling point
code (SPC) of new MSC.</p>


<p>With this feature it’s possible to change signalling point
code of MSC without deleting the whole A interface by using a few MML commands.
After changes, MTP, SCCP, and speech circuits with their old circuit identity
codes are available with a new SPC of MSC. All parameters of MTP and SCCP
will keep their old values.</p>
