Definition 
 
A HiPath 3000/5000 network can contain the following components:
 •   HiPath 3000 systems with HiPath ComScendo Service
 •   HiPath 5000 PCs with HiPath ComScendo Service
The HiPath ComScendo Service is effectively a fully-fledged HiPath node (IP softswitch) that is configured as software on a PC. Apart from the dedicated TDM characteristics, all of the features of V5.0 are available.
 •   HiPath 5000 Real-Time Services Manager (RSM) as the central administration unit in an IP network, with or without HiPath ComScendo Service
All relevant nodes (HiPath 3000 and HiPath 5000 with HiPath ComScendo Service) can be centrally administered by creating a "single system image".
The HiPath ComScendo Service Resilience feature guarantees failure tolerance for the IP workpoint clients associated with a HiPath ComScendo Service or a HiPath 3000 system. In the event of a HiPath 5000 PC or HiPath 3000 system failure or an error in the HiPath 3000 ComScendo Service, the configured IP stations (resilience stations) are assigned to a standby system (resilience destination). This can be another HiPath ComScendo Service or a HiPath 3000 system.
A standby system always represents a node in a HiPath 3000/5000 network, even if it is only a HiPath ComScendo Service that functions solely as a standby system.  
Only default features are available to the IP stations on the standby system (see Page 15-3).
This feature requires a HiPath 3000/5000 network with HiPath 5000 RSM, as monitoring and control are performed by the Feature server's Resilience Service Application (RSA). If the Feature server is unable to access a node, three additional connection attempts are initiated. If these attempts also fail, HiPath ComScendo Service Resilience is activated.
The availability of the failed system is checked again. When the Feature server can access this node again, the resilience stations are once again assigned to their home system.
HiPath ComScendo Service Resilience is not suitable for the resolution of network problems. To guarantee failsafe network operation, a suitably configured IP network is required.  
If the Feature server is unable to access two or more nodes, this indicates a network problem and HiPath ComScendo Service Resilience is not activated.  
When configuring a standby system, remember that both the "regular" stations and the resilience stations have to be set up. The default station numbers and names of the resilience stations must be deleted.
HiPath ComScendo licenses must be available for the resilience stations on the home and standby systems.  
If a node failure is detected and HiPath ComScendo Service Resilience is activated, the resilience stations are assigned to their standby system (resilience destination). The internal station numbers configured on the home system, the DID numbers, and the names of the resilience stations are transferred to the standby system. The Feature server is responsible for automatically updating the numbering tables (CAR tables) in the HiPath 3000/5000 network.
When the node is operational again, the resilience stations are once again assigned to their home system and the original situation is thus restored. On the standby system, the station numbers and names of the resilience stations are automatically deleted and the numbering tables (CAR tables) are updated in the HiPath 3000/5000 network.
HiPath 3000/5000 Manager E can be used to defined for each system client (OpenScape Personal Edition, optiPoint 410, optiPoint 420, OpenStage CorNet-IP [HFA]) whether it is a resilience station. H.323 clients are not supported.

Dependencies/Restrictions  

 Subject  
 Dependency/Restriction  
Logical ports 0 and 1  
The stations on logical ports 0 and 1 of a system (the first two lines under "HiPath 3000/5000 Manager E - Settings - Setup station - Stations") are reserved for system administration and are not supported by the feature HiPath ComScendo Service Resilience.  
Numbering  
A resilience station must be reachable at the same number on the home system and on the standby system. For this reason, only a closed numbering plan may be used.  
Open numbering is not possible.  
H.323 clients  
H.323 clients are not supported.  
Scope of functions in standby mode  
Default features (default key assignment, conference, call forwarding, callback, call hold, parking, etc.) can be used.  
Station-specific features (key assignment, groups, caller lists, call forwarding, ring no answer, etc.) are not available.  
System client: password, station type  
The settings for "Password" (Authentication active) and "Station type" (Mobile, Non mobile or Mobile blocked) defined under "HiPath 3000/5000 Manager E - Stationview - Workpoint Client: System Client" are also taken into account in standby mode.  
Applications  
Applications are not supported in standby mode.  
optiClient Attendant  
If there is an optiClient Attendant available, a manual system update must be performed when switching from normal to standby mode and vice versa (optiClient Attendant: File - Settings - System - button for system update).  
The netwide BLF function is not supported in standby mode. In standby mode, only the BLF information of the local node is displayed after the manual system update.
