over to the SMSC (Short Message Service Centre) first, which then forwards the
messages to the corresponding destination terminal. The SMSC is a software
package integrated in the PBX that is responsible for the flow of messages within
the PBX. The SMSC is configured using the AIMS Configuration Manager.
For external alarms from an alarm server the protocol ATAS or ATPC1 is used. The
alarms are not handled by the SMSC but sent directly to the corresponding desti-
nation terminal. Additional storage locations for 16 alarms are also available for
each terminal.
Alarms take priority over messages.

Connection via V.24 with ATPC1
External alarms, faults and messages from building energy management systems,
nurse paging systems, security systems, etc., can be signalled as text messages to
Office terminals via the V.24 interface of the Pocket Adapter. The connected sys-
tems must also be capable of sending and receiving AT commands defined in the
Ascotel standard ATPC1. A licence is not required for connecting external alarm
sources or messaging systems in this way.
Connection via V.24 / Ethernet with ATAS
Compared with ATPC1 the ATAS protocol provides additional possibilities for dis-
play on the system terminals (Fox menu) and allows an alarm to be triggered using
the Redkey (see "Function Redkey", page 561). The connection is also moni-
tored, and the connection set-up is password-protected. An ATAS licence is
required for enabling the protocol. This licence expands the possibilities for con-
necting external alarm and messaging sources to the PBX by providing the Ether-
net interface and the V.24 interface of the system, in addition to the Pocket
Adapter.
Interface descriptions
The ATAS and ATPC1 protocols can be disclosed to interested manufacturers of
messaging, monitoring and alarm equipment on request. Contact Support or go
