4. PBX Systems
4.3. Siemens Hicom PBX
The Siemens Hicom is a full-featured PBX that can provide thousands of ports
and many PBX voice and data features. The Hicom uses digital signaling to
control its station sets and digitized voice. The Dialogic
® PBX Integration
Board has either four or eight channels that can be connected directly to a
station module in a Siemens Hicom. The PBX has many standard features that
are supported by the PBX Integration Board, such as:
• direct inward dialing (DID)
• speed dialing
• hunt groups
• message waiting indication
• user programmable Feature Keys
• called/calling number identification
• call forwarding
4.3.1. Siemens Hicom Programming Requirements
There are specific switch programming requirements that apply if using a
Dialogic
® PBX Integration Board with either a Siemens Hicom 150 or a
Hicom 300 PBX. They allow the Dialogic ® D/82JCT-U Board to correctly
emulate an Optiset E telephone. Note that the programming is different for the
two Hicom PBXs supported, so pay attention to set these features exactly (and
assigned to the right keys) so that the Dialogic
® PBX Integration Board and
the Dialogic ® Unified API can function correctly.
Siemens Hicom 150
If the Hicom 150 is used with Optiset E phones (see Figure 5 ), special PBX
programming is required. The keys should be programmed as shown in
Figure 5 . If these keys are not programmed in this way, loop current detection,
CPID, the & (transfer) key, and message waiting do not work.
Message waiting operation in Hicom 150 is especially different from Hicom
300 although the same Optiset E phone could be used with both of these
PBXs. With a regular Optiset phone programmed as a regular phone port in
the switch, turning the Message Waiting indicator OFF cannot be done
