Asynchronous Settings
The following programming commands are not sent from the Primary System to the Secondary Systems
when Database Replication occurs:
PRG10-01, PRG10-02, PRG10-12, PRG10-13, PRG10-14, PRG10-15, PRG10-16, PRG10-45, PRG51-01,
PRG90-01, PRG90-09.
SRAM Database
The information held in SRAM is not transferred to Secondary Systems. So if a Fail-Over situation occurs
terminals may lose DND, Caller ID History, etc.
Considerations
Almost all features available at a single system are available via Net-Link.
All IP trunks must register from Primary system.
Centralised Voice Mail programming is not required because all extensions belong to the Primary system.
If there is a Voice Mail installed at the Primary system, this will service all nodes as a local Voice Mail.
InMail must be installed in the Primary system.
LAN/WAN connection – Is the IP connection between all systems suitable for NetLink.
QoS – NetLink signalling should have the highest priority possible followed by the speech data (RTP). The
general data on the network should have the lowest priority or no priority.
Applications/Devices
Below is a list of applications or devices that would be affected if the Primary System changed to a different
node, this is because the communication is between the device or application and the IP address of the
Primary System or the hardware is installed in the Primary System: -
InMail
IP extensions registered to the Primary system
All IP Trunks
SMDR/P Event Applications (MyCalls)
CTI Applications (TAPI/OAI)
Desktop Applications
AspireNet
K-CCIS
PMS
Licensing
All nodes in a NetLink network must be licensed except for the Primary System.
The licenses for all Secondary Systems are loaded onto the Primary System GCD-CP10.
E.g. If there is a ten node NetLink network, there must be a license for nine Secondary Systems loaded
onto the Primary Systems GCD-CP10.
In the event of a Fail-Over situation, the licenses from the original Primary System will be copied to the new
Primary System for a maximum of seven days. After the seven days have elapsed, the licenses will be
removed from the new Primary System so it is imperative that the original Primary System is restored to
this role.
