Application Gateway Capacity - Nortel 1000 Release Note

Application Gateway Capacity

Note
Broadcast Server delivers alerts such as emergency, IT, and weather
broadcasts in the form of text and audio messages to IP phones.
Smart Agent enables Windows PC users to initiate a call from a desk
phone by clicking a link in Internet Explorer, Outlook, and Outlook
Express.
The Application Gateway 2000 supports 1000 concurrent sessions. The
Application Gateway 1000 supports 500 concurrent sessions. Each
licensed IP phone occupies one session.
The following capacity figures assume that the host network can handle
the traffic. For larger installations, pre-testing is required to ensure that
the network capacity is adequate.
Up to four Application Gateway 2000's can be clustered, supporting
•
up to 4000 phones.
An Application Gateway supports 100 concurrent broadcasts (alerts or
•
zone pages) for phones. A broadcast is one alert sent to one phone.
Thus 100 broadcasts would be one alert sent to 100 phones or two
concurrent alerts sent to 50 phones. For a cluster, the maximum
broadcast or zone page distribution is 400 phones per cluster.
An Application Gateway supports a maximum of 256 broadcast zones.
•
An Application Gateway supports 32 concurrent buffered audio
•
streams. When an attempt to open a 33rd buffered audio stream
occurs, the phone user will see an audio unavailable error message.
An alert sent from Broadcast Server occupies one buffered audio
–
stream per Application Gateway, regardless of the size of the
distribution list.
A user listening to a message in Visual Voicemail occupies one
–
buffered audio stream. Visual Voicemail is not affected by
clustering.
Zone pages do not require audio to be buffered and are therefore
–
not subject to the limitation of 32 simultaneous buffered audio
streams.
For a list of the Nortel software requirements, please refer to the
Application Gateway Pre-Installation Checklist for Nortel Communication
Server.
