Out-of-Building Connections/Lightning Protection

The following are the only supported scenarios in which wired extensions and devices outside the main building can be connected to the IP Office system. In these scenarios, additional protection, in the form of protective grounding and surge protectors, must be fitted.

•icon_warning The fitting of additional protection does not remove the risk of damage. It merely reduces the chances of damage.

Inter_Building

Cabling Requirements

•Cables of different types, for example trunk lines, extensions, ground and power connections, should be kept separate.
•All cabling between building should be enclosed in grounded ducting. Ideally this ducting should be buried.
•A Primary Protection Box must be provided at the point where the cables enter the building. This should be three point protection (tip, ring and ground). Typically this would be gas tube protection provided by the local telephone company. The ground wire must be thick enough to handle all the lines being affected by indirect strike at the same time.

Supports up to 4 connections.
(This device was previously referred to as the Avaya 146E).
•Connection from the expansion module to the phone must be via a surge protector at each end and via the primary protection point in each building.
•The IP Office expansion module and control unit and IROB devices must be connected to the protective ground point in their building.
•The between building connection must be via earthed ducting, preferable underground. The cable must not be exposed externally at any point.

Analog Phone Extensions

icon_warning Phones Expansion module (POT or PHONE) ports only.

IP Office Barrier Box
Supports a single connection. Maximum of 16 on any expansion module.

Analog Trunks

ITWLinx towerMAX CO/4x4
Supports up to 4 two-wire lines.
(This device was previously referred to as the Avaya 146C).

For installations in the Republic of South Africa, the fitting of surge protection on analog trunks is a requirement.

For other locations where the risk of lightning strikes is felt to be high, additional protection of incoming analog trunks is recommended.

External Output Switch

ITWLinx towerMAX SCL/8
(This device was previously referred to as the Avaya 146G)

Connections from an IP Office Ext O/P port to an external relay device must be via a surge protector.

The towerMAX range of devices are supplied by ITWLinx (http://www.itwlinx.com).
