AlphaCom XE - Installation, Configuration & Operation
A100K10805
Multi-Module Network
7
Overview
7.1
If the number of subscriber lines in one AlphaCom XE26 (138 lines) is
exceeded, up to 4 modules can be combined to form a multi-module unit
with a maximum capacity of 552 lines.
The multi-module concept uses one master module and up to three
slave modules. The multi-module acts as one server with full integration
of all features. All configuration data is stored on the Master AMC board.
The connection between the modules is via an IP network similar to
AlphaNet.
Multi-module is recommended when the modules are located in the
●
same building/complex.
AlphaNet is recommended when the modules are located apart from
●
each other
Main features of AlphaCom XE IP-based Multi-Module:
Same high degree of feature integration as conventional multi-
●
modules
No additional AlphaCom hardware required
●
License is needed in the master module only
●
Point-to-point connections
●
(not in a ring as in conventional multi-modules)
The modules need to be on the same LAN
●
Optional Autonomic mode
●
The AMC Master can be set to copy its contents to the slave
-
modules over a 28 hour period
In case of master-slave communication error, the slave will restart
-
in autonomic mode, making it possible to communicate normally
within each module.
Installation
7.2
● Interconnect the modules via an Ethernet switch as shown in the
