10.15.10 EXPANSION Port

This type of port is found on the rear of IP Office control units and external expansion modules. It is used for connecting

the external expansion modules to there parent IP Office control unit.

The connection between these ports should only be done using an Avaya Expansion Interconnect Cable. No other cable

type should be used.

· Each external expansion module is supplied with a blue 1 meter (3'3'') expansion interconnect cable. This

cable must be used when connecting to expansion ports on the rear of a control unit.

· When connecting to expansion ports on an IP500 4-Port Expansion card, a yellow 2 meter (6'6") expansion

interconnect cable can be used in place of the standard blue cable. 4 Yellow cables are supplied with the IP500

4-Port Expansion card.

Expansion Interconnect Cable

The Expansion Interconnect cable is used to link expansion ports between the IP Office control unit and external

expansion modules.

· Supply: One cable is normally supplied with each external expansion module.

· SAP Code: 1m (3'3") Blue cable - 700213457, 2m (6'6") Yellow cable - 700472871.

10.15.11 EXT O/P Port

These ports are found on the rear of all IP Office control units. They are used for connection to external switching relays.

The port uses a standard 3.5mm stereo jack plug for connection.

The IP Office is able to open (high resistance), close (low resistance) or pulse (close for 5 seconds and then open) two

switches within the port. Either switch can be operated separately. These switches are intended for activation of external

relays in systems such as door opening systems.

· CAUTION: In installations where this port is connected to a device external to the building, connection must be via a

towerMAX SCL/8 Surge Protector and a protective ground connection must be provided on the IP Office control unit.

EXT O/P

Description

Switch 1.

Switch 2.

0 Volts (Ground/Chassis)

· Switching Capacity: 0.7A.

· Maximum Voltage: 55V d.c.

· On state resistance: 0.7 ohms.

· Short circuit current: 1A.

· Reverse circuit current capacity: 1.4A.

· Ensure that pins 1 and 2 are always at a positive voltage with respect to pin 3.

3.5mm stereo audio jack plugs are frequently sold as pre-wired sealed modules. It may be necessary to use a multi-

meter to determine the wiring connections from an available plug. Typically 3 (common to both relays) is the cable

screen.
