AlphaCom XE
The AlphaCom XE combines the best of an advanced communications server with the latest IP, Linux and embedded networking technologies. The AlphaCom XE provides a complete set of services, quality, reliability and security characteristics for which AlphaCom has always been recognized. Some of the special features it brings into the IP domain are wideband (7 KHz) audio, a built-in firewall, integrated web server, and low latency switching.
Separate management interface
AlphaCom XE comes with two Ethernet interfaces. A separate Ethernet interface which can be dedicated to management. This allows the administrator to build a separate administration VLAN that is dedicated only to administrators.
Network guidelines
- Maximum one way latency 150ms
- Maximum one way jitter <30ms
- Maximum Loss <1%
Bandwidth usage
A VoIP stream is using:
- On a LAN network: 85.6 kbps
- On a WAN network (IPSec encrypted): 106.4 kbps
Examples:
- A conversation between to IP stations is using 2 VoIP streams x 85,6 = 171,2 kbps
- A group call (unicast) from one IP station to 10 receiving devices (IP stations, IP Speakers), is using 11 VoIP streams x 85,6 kbps = 941,6 kbps
Unicast/Multicast
The network should support Multicast (IGMP Snooping). AlphaCom is by default using Unicast for Group audio (group calls, alarm messages etc), sending one VoIP stream to each receiving device. The maximum number of receivers is 50 when using Unicast. If more than 50 receiving devices, multicast must be used. Multicast is also recommended with less devices to lower the bandwidth usage.
VLAN
It is recommended to use a dedicated VLAN for the intercom system. Grouping users into logical networks will increase performance by limiting broadcast traffic to users performing similar functions or within individual workgroups. Additionally, less traffic will need to be routed, and the latency added by routers will be reduced.
Quality of Service
The AlphaCom uses the UDP ports 61000 to 61150 for VoIP audio. Quality of Service (QoS) is by default set on all VoIP audio packages, using Diffserv bit class EF.
Power over Ethernet (PoE)
All INCA and Turbine from Zenitel supports PoE (IEEE 802.3af standard, Class 0). Most stations (except the desktop models) can alternatively be power from a local 24VDC power supply.
The AlphaCom XE server does not support PoE.
Port use
All devices (servers and stations) are using port 80 (http) or 443 (https) for web services.
VoIP communication is using the following ports:
IP Stations
- Signaling: TCP port 50001
- Voice: UDP port 61000 - 61150
AlphaNet (interconnecting AlphaCom servers)
- Signaling: TCP port 50000
- Voice: UDP port 61000 - 61150
MultiModule (interconnecting AlphaCom servers in Master-Slave)
- Signaling: TCP port 50010
- Voice: UDP port 61000 – 61150
SIP communication
- Signaling: UDP port 5060
- Voice: UDP port 61000 – 61150
AlphaCom firewall and port usage
AlphaCom XE has an internal firewall allowing the network administrator to open and close IP services that should be able to access the AlphaCom XE from the different networks.
