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 cord-
less boards are synchronized.
The system views each mobile telephone (mobile station) as a corded telephone. During ad-
ministration, 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 a mobile telephone moves into the area of a different radio switching location ("cur-
rent-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). 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.
