DS Ports (RJ45)

These ports are used for connection from an RJ45 structured cabling system to digital station phones supported by the IP Office. DS ports are provided by IP500 Digital Station Cards, IP500 ATM Combination Cards and IP500 Digital Station external expansion modules.

Though the RJ11 to RJ11 cables supplied with some phones can be plugged directly into RJ45 ports including those on IP Office modules, this is not recommend as the connection lock is not positive and may become disconnected.

•DS ports on external expansion modules can be connected to out-of-building extensions. If this is the case, connection must be made via suitable protective devices at each end and via each building primary protection. In addition, the Digital Station module must be connected to a protective ground.

•DS ports on base cards within the control unit must not be connected to out-of-building extensions.

Structured Cabling Line Cord

This is an RJ45 to RJ11 cable suitable for connection from a structured cabling system RJ45 port to a DS phone. It can also be used for two-wire analog phone extensions.

This cable is not suitable for connection from an Avaya 1151D1/B2 power supply unit to a DS phone with a EU24 or XM24 add-on module. In those cases the cables supplied with the power supply unit and the add-on module should be used.
