+// This class is an example implementation of a bearer-mobile network session. It is intended as a guide only and does
+// not employ any advanced bearer selection algorithms. It is envisaged that users of these classes will want to derive their own
+// implementations from CIPNetworkSession.
+// This is part of an ECOM plug-in
