Expansion Stages and System Capacity
• 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.

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.
• TWP Connection
This licence is used to connect to the Telephony Web Portal (TWP). While it is vis-
ible in AMS and on the licence server, it cannot be deleted; instead it is automat-
ically enabled whenever user-based TWP licences are available.
• Enterprise Voice Mail
If the functionality of the basic voice mail system is insufficient, the voice mail
system can be expanded. This licence provides two audio channels for recording
or playing back audio data for voice mail. Auto Attendant or call recording. The
licence also increases the voice memory capacity and allows e-mail notification
whenever new voice messages are received, the forwarding of voice messages,
the call recording, and the complete use of the voice mail menu by remote re-
trieval.
Notes
– Additional audio channels require additional Audio Record & Play
Channels licences. A licence is required to use the Auto Attendant
function.
– In a VoIP environment VoIP channel licences are also required for
converting the voice data when using the internal voice mail sys-
tem.
