11.5  
Multi-SLC and System-Wide Networking 
 
You can install up to four SLCN boards in HiPath 3800. For the total cordless station mobility (roaming and seamless connection handover) within a system, the radio fields of these cordless boards are synchronized.
The system views each mobile telephone (mobile station) as a corded telephone. During administration, a fixed port on the system's "home cordless board" is assigned to the MT; this is used for addressing the MT.
As soon as an MT moves into the area of a different radio switching location ("current-location cordless board"), an extension connection is switched using a DSS1 connection initiated by the cordless board. The home and current-location cordless boards exchange a networking protocol (User-to-User Signaling UUS) over this extension connection to support full mobility (see Figure 11-3).
This function can be used not only within one system, but also among systems (among nodes) because the CorNet NQ used for networking supports the UUS protocol (note: for the system-wide extension connections, you may have to take additional B channels into consideration for the permanent connection paths (CorNet NQ, see Section 11.6 "Planning Notes for Networked HiPath 3000 Systems Featuring Network-Wide Roaming"). That means full mobility across the radio fields of the different cordless systems. All handset features (callback, team functions, voicemail, etc.) remain intact. The network-wide handover feature is only exception here as it is not currently supported.
