MultiModule

MultiModule: Up to 4 modules, 552 subscribers

MultiModule is a way of interconnecting up to 4 modules in a master/slave configuration. In some documents also refered to as InterCardCage, ICC.

You can link up to 4 modules.

Overview

If the number of subscribers in one AlphaCom E26 (138 lines) is exceeded, up to 4 modules can be combined to form a multi-module with a maximum capacity of 552 lines. The MultiModule concept use one master module and up to tree slave modules. The MultiModule acts as one exchange with full integration of features. All configuration data are stored on the Master AMC board. The master module controls the resources in the slave modules using the ICC Protocol.

The connection between the modules is via IP network similar to AlphaNet.

• MultiModule is recommended when the modules are located in the same building/complex
• AlphaNet is recommended when the modules are located apart from each other

The main features of AlphaCom E IP-Based MultiModules are:

• Same high degree of feature integration as traditional MultiModules
• No additional AlphaCom hardware required
• Licenses are needed in each of the modules<br\>-The license key is common for AlphaNet and MultiModule<br\>-Licenses are by default used for MultiModule<br\>-MultiModule always use VoIP connections in a dynamic way
• Point to point connections (not in a ring as in traditional MultiModules)
• The modules do not need to be on the same LAN
• MultiModule uses fixed jitter buffer size of 10 ms
• Optional Autonomic mode<br\>-The AMC Master can be set to copy its content to the slave modules over a 28 hour period<br\>-In case of master - slave communication error the slave will restart in automatic mode

MultiModule configuration using analog AGA boards

Connecting master and slave over AMC IP

An ethernet switch is needed to connect the 3 slaves and the master

Installation

• Interconnect the modules via an Ethernet switch as shown in the figure on the left.
• Perform a cold start to each module separately
• AlphaWeb:<br\>-Assign an IP Adress to each module<br\>-Enter the license key to enable the VoIP channels
• AlphaPro:<br\>-Enter the IP adress of the slave modules.

Limitations in Slave Modules

Slave modules support analogue stations only, no other types of inputs or outputs. Only the master module supports:

• -Remote Control Inputs - RCI's
• -Remote Control Outputs - RCO's
• -Serial port drivers and other central equipment and licenses like RIO, Paging, AlphaNet, SIP trunk node and SIP registrar Node
