Networking
• B-Channels on PRI Cards
In addition to the 10 B channels that can be used without a licence on each PRI
interface card, one extra B channel is enabled per licence. A maximum of 30 B
channels are possible per PRI interface. Unlike the B channels that can be used
without a licence and which are restricted to the relevant PRI interface card, the
licensed B channels can be used on any PRI interface card.
Aastra Intelligent Net
In an AIN the licence is always acquired on the Master. For each licence
an additional B channel is available on a PRI interface card 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 requires one licence per channel.
Aastra Intelligent Net
In an AIN all the SIP licences are always acquired for the Master. The
number of licences determines the maximum number of simultane-
ously active voice channels, regardless of the nodes on which they are
currently being used. Requirement: The DSP resources on each node
must be available and allocated accordingly.
• Lync Option for SIP Access Channels
This additional licence enables the use of a SIP access channel with Lync-specific
options and features. It is required for each channel in addition to a
Channels licence.
Private networking
• QSIG Networking Channels
These licences are used to implement a private leased-line network with QSIG by
enabling a specific number of simultaneously outgoing QSIG channels. Two li-
cence levels are available (see
Aastra 470 as of R3.2
syd-0337/1.6 – R3.2 – 09.2014
