===Defining Cluster Node===
 +
Cluster programming is an option to simplify programming and updating of numbers in AlphaNet when operating with integrated number series. To get access to the '''AlphaNet Visibility''' menu, the server must be assinged a ''Cluster Node Number'' in the '''Exchange & System''' window. The Cluster Node number can be any number between 1-255. Nodes with the same ''Cluster Node Number'' are members of the same cluster.

Cluster programming is a option to simplify programming and updating of numbers in AlphaNet when operating with integrated number series. To get access to the '''AlphaNet Visibility''' menu, the exchange has to be given a ''Cluster Node Number'' in the '''Exchange & System''' window. Nodes with the same ''Cluster Node Number'' (1-255) are members of the same cluster.
+
When using AlphaNet '''Static''' License, one have to configure fixed Audio Connections between the AlphaCom servers. This is done from AlphaPro, [[Exchange_%26_System_(AlphaPro)#NetAudio|Exchange & System > NetAudio]], where you specify that a VoIP channel in the "Source" exchange has a static (fixed) connection to a VoIP channel in the "Destination" exchange.

*'''Cluster Global'''<br /> The directory number and name will immediately be copied to the other exchanges in the cluster node as a [[Call remote station feature|global number]]. If the number exists from before in any of the other exchanges, it will be deleted. ''AlphaNet Visibility'' will be set to ''Cluster Automatic'' in the other exchanges.<br />'''Modify'''<br />When modifying the number or name of an existing global user, you must do the modification in the exchange were the user is physically connected, i.e. were the visibility is set to ''Cluster Global''.

AlphaNet Overview.PNG

AlphaNet is Zenitel's internal networking technology made for critical communications. Some of the highlighted features of AlphaNet are:

  • Group and conference calls
  • VoIP bandwidth management
  • Priority handling of events and resources
  • Alternative routing
  • Backwards compatibility
  • All features available over the network

Up to 254 ICX-AlphaCom servers can be interconnected in AlphaNet. One server can have up to 100 links to other servers.


VoIP AlphaNet Configuration

The following configuration is used in the examples in this article.

AlphaNet2.png


AlphaWeb settings

In each node you must:

  • Set a unique IP address
  • Insert an AlphaNet license
  • Edit the firewall

Setting IP address

AlphaNet3.png


Inserting AlphaNet license

Every AlphaCom node requires an AlphaNet license. The license controls the number of simultaneous calls to and from an AlphaCom.

AlphaNet4.png


Editing the firewall

TCP port 50000 must be enabled in for signaling between the nodes, and UDP ports 61000-61150 for VoIP audio:

AlphaNet5.png


Create all the nodes in the AlphaNet

Create the AlphaNet database and define the first node by clicking the + sign as highlighted below. Give the node a descriptive name and select which network interface to be used to communicate with other nodes.

CreateNetwork.png


CreateNode1.png


Add more nodes to the database by clicking the + sign as highlighted below. Give the node a descriptive name and select which network interface to be used to communicate with other nodes.

CreateNode2.png


CreateNodeC.png


Note icon In some cases it is not desired to configure all the exchanges in the AlphaNet from the same AlphaPro database. In that case you should add the remote exchange in the network, but uncheck the tick-off for "Create exchange database".


Create AlphaNet routing

Routing must be specified from all nodes to all nodes. For each node:

CreateRouting.png


If the Source Node is an AlphaCom XE7/20/26 and the Destination Node is an ICX-AlphaCom or AlphaCom XE1, enable “IP Only”

Note icon In an AlphaNet of XE7/20/26 and ICX-AlphaCom or AlphaCom XE1, call recording should be enabled in the ICX-AlphaCom or AlphaCom XE1 node only. If call recording is required in the XE7/20/26 node, the stations must be IP Stations. This is due to the Voice Switching operation across AlphaNet not being compatible with the Recorder Interface.


Transit Routing

In the case of Transit Routing, where the Remote nodes are connected via a Central Node, you need to direct the traffic via the Central Node.

Dial plans

Calling from station A in one node to station B in another node can be achieved in different ways.

*) Prefix to node 1 and 2 are included after Factory Default (Directory numbers 54 and 55)


DialPlansPrefix.png


DialPlansSemi.png


DialPlansGlobal.png


Global Group Calls

A Global Group consists of one Local Group from each node

GlobalGroup1.png


  • Factory Default includes Global Group 1 to 10, Directory Numbers 9001 – 9010
  • Each Global Group can contain one local group call from each node
GlobalGroup2.png


Each node broadcasts its own global group membership to the other nodes after:

  • AlphaPro Send operation
  • Restart of AlphaCom
  • Dialing service code 7879

In this way each node knows which global groups the other nodes are members of.

Cluster node programming

Defining Cluster Node

Cluster programming is an option to simplify programming and updating of numbers in AlphaNet when operating with integrated number series. To get access to the AlphaNet Visibility menu, the server must be assinged a Cluster Node Number in the Exchange & System window. The Cluster Node number can be any number between 1-255. Nodes with the same Cluster Node Number are members of the same cluster.

Cluster1.png


Cluster Global

Setting Visibility = “Cluster Global” on a User in node 1...

Cluster2.png



...will automatically create a Global Number (feature 83) in node 2 (and all other nodes in the cluster)

Cluster3.png


Note icon If the number already exists in the other cluster node(s), you will get a warning


It is possible to create Global Numbers for many (or all) Users in one operation:

  • In Directory & Features select multiple users (feature 9) by click and shift + click.
  • Set AlphaNet Visibility = “Cluster Global”
  • Check “Apply to all Directory Numbers with this feature”
Cluster4.png


Note icon If a number already exists in the other cluster node(s), it will be deleted without warning


Cluster Identical

Instead of creating the same local feature in every node, do it once:

  • Set Visibility = “Cluster Identical” on a Feature in one node...
Cluster5.png



...and a copy will automatically be created in all other nodes in the cluster.

2-line static license - details

An AlphaCom server with a 2-line static license allows maximum two simultaneous AlphaNet calls.

Static Licenses are typically used in:

  • Low traffic 2-node system
  • AlphaNet with multiple nodes were “end nodes” needs to call central node” only

When using AlphaNet Static License, one have to configure fixed Audio Connections between the AlphaCom servers. This is done from AlphaPro, Exchange & System > NetAudio, where you specify that a VoIP channel in the "Source" exchange has a static (fixed) connection to a VoIP channel in the "Destination" exchange.

Each VoIP channel is identified by a virtual physical number:

  • VoIP Channel 1 = Physical Number 605
  • VoIP Channel 2 = Physical Number 606
  • ..
  • ..
  • VoIP Channel 30 = Physical Number 634

Example - Low traffic 2-node system

Two AlphaCom nodes, both with 2-line Static License

Configuration example: Two nodes, both with 2-line Static License



NetAudio configuration:

Configuration of 1st AlphaNet connection using VoIP channel (605). Insert a second AlphaNet connection using VoIP channel (606)



Example - AlphaNet with multiple nodes, “end nodes” needs to call central node” only

Each "end node" has a Static 2-line license. The central node has an 8-line Dynamic license



NetAudio configuration:

  • "NetAudio" must be configured in all "End nodes"
  • No configuration of "NetAudio" required in the Central node
NetAudio configuration in an "End node". A VoIP channel (here 605) is linked to a "Dynamic license" in the Central node



License requirements

Every node requires an AlphaNet license. The license controls the number of simultaneous calls to and from an AlphaCom. There are two types of AlphaNet license:

  • Dynamic license: Pool of VoIP channels - automatically allocated when needed

  • Static license: VoIP channels must be fixed towards specific node(s)

VoIP Bandwidth

AlphaNet provides bandwidth management limiting the VoIP bandwidth to not take more capacity than provisioned.

  • Each active call uses approx. 100 kbps
  • Maximum bandwidth usage: Number of simultaneous calls x 100 kbps
    • Example: System with16 Dynamic Lines
    • Max. possible bandwidth usage is 16 x 100 kbps = 1.6 Mbps
Exact bandwidth figures


Additional information

Priority handling of events and resources

All calls and events that are sent between nodes are marked with priority. This allows the system to act upon the priority, presenting and handling the events and calls in the correct order. If a high priority call is set up when all VoIP channels are occupied, AlphaCom will immediately release the call with the lowest priority allowing the high priority call to proceed.

Alternative routing

Alternative routing of calls allows call completion even when the primary AlphaNet route is down.

Note icon Alternative routing in mixed environments (AMC9 and AMC-IP) is not supported!


Backwards compatibility

AlphaCom provides 100% backwards compatibility between traditional AlphaNet technologies and new VoIP AlphaNet. The backwards compatibility allows mixing of the AlphaCom nodes working over IP with current nodes. This makes the configuration of the system very easy, allowing quick and precise maintenance.

Troubleshooting

In AlphaWeb, System Monitoring > AlphaNet, some information about the AlphaNet status is listed.

  • If the node is listed: Routing information in AlphaPro is correct. If not, check NetRouting in AlphaPro, then do a Send All followed by a reset.
  • Press Ping Test to check Status and Ping Time:
    • Down, and no answer to Ping: No TCP/IP communication to remote node. Check network, cables, switches etc...
    • Down, but Ping time is returned: IP communication is OK, but not AlphaNet. Most likely blocking of TCP port 50000 in internal or external firewall. Check if "AlphaNet" is enabled in Filters.
    • Up: AlphaNet communication is OK

Note: The node with the lowest node number is TCP-Client, the highest is TCP-Server.
