ISDN interface
Aastra 400 supports the ISDN protocols ETSI, DSS1 and QSIG. Besides the possibility
of networking various systems into a PISN (Private Integrated Services Network) via
the ISDN interface, these protocols also provide various functions that can be used
for connecting external applications (e. g. IVR systems, fax server, voice mail sys-
tems, unified messaging systems, DECT radio systems).
2. 6. 2. 5
Configuration
The Aastra 400 communication servers are configured using the AMS application,
which can communicate with the communication servers via different interfaces (Ether-
net, ISDN). A proprietary protocol is used for this purpose. With the Open Interfaces
Platform the configuration interface is accessible for application manufacturers. The
web-based configuration tool WebAdmin is also available for single systems.
2. 6. 2. 6
System monitoring
The system status is monitored using the SEM (System Event Manager) application,
which is included in AMS. The application gathers and outputs the system mes-
sages and alarms. The system messages and alarms are also accessible via the
Open Interfaces Platform.
2. 6. 2. 7
Call logging
The Call Logging Manager includes data acquisition for incoming traffic (ICL), outgoing
traffic (OCL) and the counting of the acquired call charges according to a variety of cri-
teria. The data can be retrieved via different interfaces and subsequently processed.
2. 6. 2. 8
Hotel Management Systems
A PC can be connected via Ethernet to run functions in Aastra 400 using command
language. A special command set is available for communicating with hotel man-
agement systems. These commands can then be used to carry out user-specific
polling operations (e.g. room status) and configurations (e.g. wake-up time).
2. 6. 2. 9
Voice over IP
Aastra 400 provides gateways for implementing Voice over IP. Besides the possibil-
ity of networking systems via IP, IP system phones and SIP phones can also be oper-
ated on Aastra 400 via the Ethernet interface.
