Figure 9: Routed Head Quarter Configuration with Branch Office
In Routed Head Quarter Configuration with Branch Office the network settings must comply
with the requirements for Routed Head Quarter configuration (for the network settings within
Routed Head Quarter) and with the requirements for Branch Office configurations (for the
network settings between Branch Offices, including the Branch Office with Routed Head
Quarter).
Multi Site Mobility Network Configuration:
Multi Site Mobility Network (MSMN) Configuration makes it possible to use portable DECT
handsets on various MCDN nodes where each node is a CS 1000 system plus the
corresponding SIP DECT system. MSMN allows roaming between independent SIP DECT
systems installed on separate Call Servers (connected by trunks). Handover between
independent SIP DECT systems is not possible.
A SIP DECT system on an individual MCDN node can be any of the previously described
configurations: Basic (Simple), Routed Head Quarter, Branch Office, or Routed Head Quarter
with Branch Office.
MSMN requires unrestricted MSMN package 370 and a number of free wireless visitors
licenses, which are regulated by ISM mechanism. If there are only restricted MSMN packages
or if there are no wireless visitors licenses the following occurs:
• A new UEXT SIPL visitor client cannot be created (the VSIT and HMDN prompts are not
shown).
• A non-visitor UEXT cannot be changed to UEXT SIPL visitor (the VSIT and HMDN
prompts are not shown).
