To ensure electrical system grounding integrity, follow the isolated ground topology for all Meridian 1 / Succession 1000M Large System equipment implementations. Isolated ground provides the best method for avoiding the introduction of ground noise to the system from other external equipment.
When isolated ground topology is not possible, an alternative grounding method may be used if it provides the required Meridian 1 / Succession Single Point Ground (SPG) reference. The SPG source must be the AC Equipment Ground (ACEG) bus located inside the Meridian 1 / Succession service panel. Service panel grounding facilities must be properly referenced to an acceptable AC grounding source, which provides a low noise, low impedance path.
Installations that have elected not to deploy an isolated ground methodology will be noted during Nortel system audits. Locations experiencing system operational performance difficulties attributed to ground noise or improper grounding methods will be required to rectify the issue.
