Integrated Gateways
All PBXs also have gateway functionality
which means they can be used to connect
to the ISDN network. Furthermore, the IP302
has two analogue interfaces, e.g. to connect
a fax machine. All PBXs support the standard
T.38 (fax over IP). Other non VoIP capable de-
vices can also be used by means of approp-
riate adapters; such as the IP adapters IP22,
IP24 or IP28 which have two, four or eight in-
terfaces, accordingly.
A second Ethernet interface can optionally be
used on all innovaphone telephone systems
e.g. for IP routing, for a redundant network
connection or for connecting to a demilitari-
sed zone (DMZ).
innovaphone operating system
innovaphone has developed and uses its
own real-time operating system which has
been reduced to essential functions. There-
fore, users do not have to worry about secu-
rity gaps, which are the usual cause of attack
on Windows and Linux systems.
The proprietary operating system is also re-
sponsible for the quick booting time: measu-
rements in our laboratory proved that on ave-
rage, the innovaphone system is ready for
operation just 10 seconds after being swit-
ched on. This is advantageous especially if
there has been an error or when rebooting
the system after making configuration chan-
ges.
The fact that the firmware is identical on all
systems also has a positive effect on the
amount of training required by administra-
tors.
Scalability
According to innovaphone, one single IP6000
can serve approximately 2,000 subscribers. If
this number is exceeded, the gateway func-
tionality should be transferred to another de-
vice. This would enable a further 8,000 users
to be connected. However, a system of this
size should be further cascaded in order to
distribute the load. Several primary multiplex
connections can thus be distributed amongst
other systems, providing additional redun-
dancy.
Using the location concept means that the-
re is basically no limitation to the number of
connections in an overall solution. Additional
subscribers can be covered by integrating
additional hardware.
In addition, and this isn’t self-evident, the
innovaphone solution can also be scaled
downwards. The IP302 enables small branch
offices and locations to be integrated econo-
mically in larger PBX infrastructures.
Terminals
The terminals are the result of development
co-operations with companies such as Kirk,
tiptel, swisscom, ascom and Funke+Huster.
This diversity however comes at the expense
of a uniform terminal design concept. How-
ever, in a positive sense, it could be said that
innovaphone has sought out the perfect de-
velopment partner for every operational pur-
pose.
The range of terminals starts with the simple
IP110 with its five line display, over the IP200
with alphanumeric keyboard to the IP240
with its seven line display and eight function
keys. The IP230 can be extended using a ma-
ximum of three extension modules to enable
max. 100 function keys. The IP150 is a spe-
cial case (see Figure 1): It is weather-proof,
its special housing protects against vanda-
lism, rendering it suitable for outdoor use.
The IP DECT gateway IP1200 cannot really
be classified as a terminal, nevertheless, it
is worth being mentioned here as part of a
cordless solution. The integrated GAP com-
patible base station can for example be used
by the DECT telephones IP52, IP54, IP55/56
(see figure 2) and IP64. The WLAN telephone
IP72 results from a development cooperation
with Ascom and provides a real alternative to
the DECT solution. The very robust telephone
has more than 8 hours talk time and almost
40 hours standby. It supports the standards
