HiPath Cordless Office
2.10.3 Multi-SLC and Cross-System Networking
You can install up to four SLCN boards in HiPath 3800. The radio fields of these cordless boards
are synchronized for full cordless station mobility (roaming and seamless connection handover)
in a system.
The system treats every handset (mobile station) as a corded device. During administration, a
fixed port on the system’s "home cordless board" is assigned to the MT; this is used for addressing
the mobile telephone.
As soon as a mobile telephone 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 2-15).
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 systemwide
extension connections, you may have to take additional B channels into consideration for
the permanent connection paths (CorNet NQ, see Section 2.10.4). Full mobility is guaranteed
across the various cordless system hops. 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.
