Line protection grounding

In conjunction with line protectors, proper system (PBX) grounding is
essential to minimize equipment damage. Nortel recommends following the
grounding connection requirements as described in Communication Server
1000M and Meridian 1 Large System Installation and Commissioning. This
requirement includes connecting the ground for the protection devices to
the approved building earth ground reference. Any variances to these
grounding requirements could limit the functionality of the protection device.

Line and telephone components

Because testing of the line protectors was limited to the line cards and
telephones shown below, only these components should be used for
off-premise installations.

Telephones

•Meridian Modular Telephones(digital)
•Meridian Digital Telephones
•Standard analog (500/2500-type) telephones

Line cards
