IP403 Office Platform General
The IP403 Office system platform supports up to eight digital and two analog telephones. This can be
expanded, by use of extension modules, to 100 extensions.
Two variants are available and are equipped as follows:
• DT ports - Support Avaya 2000 series telephones.
• DS ports - Support Avaya 6400 and/or Avaya 4400 series telephones.
Both ports can be set for either µ-Law or A-Law PCM encoding. At default DT ports are set to A-Law
and DS ports are set to µ-Law. However, these can be switched in software (refer to the
Administration Manager Manual for details).
Connection to trunks is via one* of the following integral interface modules:-
Single PRI E1 (30 trunks) or Single PRI T1 (23B+1D or 24B trunks - USA only) or
Quad BRI (8 trunks) or Analog 4 (loop start trunks ).
If Analog 4 modules are used, a second module can be fitted in Slot A.
See page 39 for installation and page 32 for country specific variants.
An eight port auto-negotiating 10/100 BaseT LAN hub provides access to networks and/or up to eight
IP telephones. (Where IP telephones are to be used, the hub should be connected to a suitable
switch, e.g. an Avaya Cajun P130.)
Expansion Modules
Optional Expansion Modules (see page 27) allow the IP403 Office to be expanded to 100
extensions. These modules (with the exception of the WAN3 – see below) are connected via the
Expansion Port sockets that are located on the back of each unit. Up to 3, in any combination, of
the following Expansion Modules can be supported by the IP403 Office base unit.
• IP400 Digital Terminal 16/30 or Digital Station 16/30
Two variants of both (16 or 30 extensions) for digital telephones (see page 27). Hence, if all 3
extension modules are IP400 Digital Terminal/Station 30s, then the maximum of 100 extensions
will consist of 90 digital extensions, plus the base unit's 2 analog extensions and 8 digital
extensions.
• IP400 Phone 8/16/30
Three variants (8, 16 or 30 extensions) for analog telephones (see page 28). Hence, if all 3
extension modules are IP400 Phone 30s, then the maximum of 100 extensions will consist of 90
analog extensions, plus the base unit's 2 analog extensions and 8 digital extensions.
• IP400 So8
An S-bus module that provides 8 Basic rate ISDN interfaces (see page 29).
• IP400 WAN3
Provides support for a further 3 digital leased line (WAN) connections (see page 30). These
expansion modules are connected to the IP403 Office unit via one of the LAN Ports located on
the front of each unit.
• IP400 Analog Trunk 16
Provides support for up to 16 Loop Start or Ground Start analog trunks (see page 31). Two power
fail sockets are also provided.
Integral Modules
In addition the IP403 Office can be fitted with either or both of the following optional Integral Modules
(see pages 40 and 41):
• Voice Compression Module (VCM)
Supports VoIP applications (e.g. using Avaya 4600 IP series telephones connected via LAN
ports). Available in 5,10 and 20 channel variants.
• Dual Modem Module
Allows termination of two simultaneous analog modem calls up to and including 56kbps.
