4 analog trunk ports or 4 BRI channels (2 ports). The trunk daughter card cannot be

removed or replaced with another type of trunk daughter card.

• External expansion modules — External expansion modules are used to add additional

analog and digital ports. If the control unit is fitted with a 4–port expansion base card, then

up to 12 external expansion modules are supported. The following external expansion

modules are supported:

- Analog trunk module — This module rovides an additional 16 analog ports for

connection of analog trunks. It supports both loop-start and ground-start trunks.

- BRI So8 module — This module provides 8 ETSI BRI-So ports for the connection

of ISDN devices. This module is not intended to support BRI trunks.

- Digital station module — This module provides, depending on variant, an

additional 16 or 30 DS ports for supported Avaya digital phones.

- Phone module — This module provides, depending on variant, an additional 16 or

30 phone ports for analog phones.

• Power supplies — The 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.

• Mounting kits — The 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 control unit can be wall mounted. However, the control unit cannot

support any external expansion modules when 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.

• Phones — B5800 Branch Gateway systems support a variety of Avaya digital and IP

phones plus analog phones.

• Application DVDs — The B5800 Branch Gateway applications can be ordered on a

number of DVDs. In addition they can be downloaded from the B5800 Branch Gateway

section of the Avaya support web site (http://support.avaya.com).
