Access to the applications server is normally via the WebAdmin configuration tool,
which means the front-side interfaces of the applications card are not needed.
Note
For licensing reasons the front-side connections are to be used for main-
tenance purposes only. Installing user-specific applications is prohibited.

System capacity
System capacities are defined on the one hand by the existing hardware with its ex-
pansion possibilities and on the other by the limits set in the software. The software
limits can be partly expandable by licences.
Note:
The values in the following three tables relate to a communication server
with an Aastra 470 Expansion expansion licence. Without this licence the
system is limited to the first 36 users in the numbering plan, which means
many values in the table are not valid.

System capacity
The number of slots, interface cards and system modules per communication
server have already been mentioned in the previous chapters and are not listed
separately in this chapter.
