The communication server is capable of communicating with up to 10 different ESMEs.
Examples of ESMEs include the IMS (Integrated Message Server) and Mailgate (both
Ascom Wireless Solutions products).
MiVoice Office 400 ensures the connections between the IMS and the 9d phones. 9d
phones do not register with under the GAP standard but as system phones. The IMS
communicates with the communication server via the LAN interface. The SMPP proto-
col is used for this purpose.
9. 11. 3 External messaging and alarm systems
External messages in Short Message format (SM) are signalled to the PBX by an SM
server (e.g. IMS: Integrated Message Server) via the Ethernet interface using the
SMPP protocol logged in the communication server.
The ATAS protocol is used for the external alarms of an alarm server. The alarms are
routed directly to the corresponding destination terminal. Storage locations for alarms
are available for each terminal.
External messages and external alarms are handled differently in the communication
server.
9. 11. 3. 1 Message handling
External and internal messages are first sent to the SMSC (Short Message Service
Center), which then forwards the messages to the corresponding destination phone.
The SMSC is a software package integrated in the communication server that is re-
sponsible for the flow of messages within the communication server.
Up to 16 messages can be buffered for each phone. Undeliverable messages (e.g.
phone memory full) are buffered in the SMSC (up to 400 messages). Overflow of the
phone memory is signalled accordingly on the display of the system phone. A new at-
tempt at delivering buffered internal messages is made after a configurable resend pe-
riod. The messages are definitively deleted once the validity period, which is also con-
figurable, has expired. With external messages the validity period is usually also trans-
mitted. If not, the internal setting is also used. The resend period for external mes-
sages is always one quarter of the validity period.
WebAdmin can be used to delete all pending messages or messages that are more
than three days old on all system phones (see Tab. 220
).
If the external message server is capable of handling short messages (SMS), then it is
anESME (External Short Message Entity). An ESME always communicates with the
communication server via LAN.
