CHAPTER 3 EXPANSION STAGES AND SYSTEM CAPACITY
• Silent Intrusion
This licence is needed for the Silent intrusion feature, which is similar to the Intrusion feature. The
difference is that the user intruded upon receives neither a visual nor an acoustic signal of the in-
trusion. The feature is used mainly in call centres. One licence is required per system /AIN.
Resources
• Mitel SMBC Base licence
This basic licence is required for Mitel SMBC. It contains 10 User licences (see User licences). With
this basic licence no other licences are needed for setting up a Mitel Advanced Intelligent Network
(AIN).
• VoIP Channels for Standard Media Switch
NOTE: This licence is required for Mitel 415/430, Mitel SMBC and Mitel 470 only. For Virtual Appli-
ance, the VoIP channels of the integrated Mitel Media Server are made available and do not require
any licences.
This licence enables the conversion of voice channels for VoIP-non-VoIP connections and is used for IP
terminals, SIP terminals, SIP access channels or to operate an Mitel Advanced Intelligent Network. High
voice data compression is possible with the G.729 VoIP channels. An additional voice channel is activated
with each licence.
NOTE: If VoIP mode is set to G.711, two G.711 VoIP channels per system can be used without a licence.
• Theoretically there are no VoIP channel licences in a pure VoIP environment (only IP/SIP phones on
the system and connection to the public network via an SIP provider). However, as soon as voice
mail functions, the announcement service or music on hold is used, VoIP channel licences are
required as the use of these functions entails a conversion of the voice data.
• Mitel Advanced Intelligent Network
In an AIN the licence can also be used for the connections between the nodes. Two VoIP channel
licences are required for each node connection. The licences are always acquired for the Master.
The number of licences determines the maximum number of simultaneously active conversions, re-
gardless of the nodes on which they are currently being used. Requirement: The media resources
on each node must be available and allocated accordingly. If Virtual Appliance is used as Master,
the VoIP channels of the master node are made available without a licence from the integrated Mi-
tel Media Server. However, for the satellites' VoIP channels, the licences must be purchased.
Networking
• B-Channels on PRI Cards
10 B-channels can be used without licences for each PRI interface. These channels cannot be trans-
ferred to other PRI interfaces. An additional channel is activated with each licence. These licences
are in a pool and are used from any PRI interface, if necessary (per call).
NOTE: Mitel Advanced Intelligent Network: In an AIN the licence is always acquired on the Master.
For each licence an additional B channel is available on a PRI interface of any node, depending on
where the B channel is currently being used.
• SIP Access Channels
The connection of the system to a SIP service provider or the networking of the systems via SIP re-
quires one licence per channel.
