Ascotel IntelliGate 2025/2045/2065
Part 2 Features 557
Up to 16 messages can be buffered for each terminal. Undeliverable messages
(e.g. terminal memory full) are buffered in the SMSC (up to 400 messages). Over-
flow of the terminal memory is signalled accordingly on the display of the system
terminal. A new attempt at delivering buffered internal messages is made after a
configurable resend period. The messages are definitively deleted once the validity
period, which is also configurable, has expired. With external messages the valid-
ity period is usually also transmitted. If not, the internal setting is also used. The
resend period for external messages is always one quarter of the validity period.
AIMS can be used to delete all pending messages or messages that are more than
three days old on all system terminals (see Tab. 2.213).
The SMSC is configured using the AIMS Configuration Manager:
Tab. 2.309: SMSC settings
If the external message server is capable of handling short messages (SMS), then
it is an ESME (External Short Message Entity). An ESME always communicates with
the PBX via LAN. The PBX is capable of communicating with up to 10 different
ESMEs. Examples of ESMEs include the IMS (Integrated Message Server) and Mail-
gate (both Ascom Wireless Solutions products).
The communication settings between the SMSC and the ESME can be configured
in AIMS:
Tab. 2.310: ESME settings
