Avaya IP Office 500 Control Unit

The following are the typical components of an IP Office IP500 system.

IP Office IP500 System Unit

The control unit holds the main configuration and performs the routing and switching for telephone calls and data traffic. Each control unit includes LAN ports, slots for additional internal cards and in some cases integral digital and analog phone ports.

IP500 Base Cards

The IP500 control unit has slots for up to 4 IP500 base cards. These can be used to add analog extension port, digital extension ports, voice compression channels and some legacy IP400 cards.

IP500 Trunk Daughter Cards

Many of the IP500 base cards can be fitted with a IP500 daughter card in order to support various types of trunk connections.

IP400 Cards

The IP500 Legacy Carrier base card can be used to allow IP400 trunk cards and IP400 VCM cards to be added to the IP500 control unit.

IP500 External Expansion Modules

Additional analog and digital extension ports can be added using a number of IP500 external expansion modules.

The IP500 also supports IP400 external expansion modules except for WAN3 modules.


Power Supplies

The IP500 control unit has an internal power supply unit. Each external expansion module is supplied with an external power supply unit. Additional power supply units may also be required for IP phones and some phone add-ons.

Power Cords

Depending on the locale, different power cords need to be ordered for each control unit, external expansion module and any phones or devices using external power supply units.


The IP Office is designed primarily for connection to a structured cabling system using CAT3 UTP cabling. This approach allows telephone and data traffic to share the same wiring infrastructure and simplifies equipment moves.

Mounting Kits

The IP500 control unit can be used free-standing, with external expansion modules stacked above it. With optional rack mounting kits, the control unit and external expansion modules can also be rack mounted. Alternatively with an optional wall mounting kit the IP500 control unit can be wall mounted.

Surge Protectors and Barrier Boxes

Where the installation includes extensions in other buildings additional protective equipment is required. This equipment may also be required in areas where the lightning risk is high.


IP Office systems support a variety of Avaya digital and IP phones plus analog phones.

License Keys

Various IP Office features and applications require a license key to be entered into the system's configuration. Each key is a 32-character text string unique to the feature being activated and the serial number of the Feature Key dongle (see below) installed in the system.

Feature Key Dongle

A uniquely numbered dongle used to validate license keys. For the IP500 control unit a Smart Card type Feature Key dongle is mandatory for correct system operation even if no licensed features are being used.

Application CD's/DVD's

The IP Office applications can be ordered on a number of CD's. In addition they can be downloaded from the IP Office section of the Avaya support web site.
