2. Electromagnetic Compatibility

GR-1089-CORE

The electromagnetic compatibility and electrical safety requirements for Carrier Grade

equipment are primarily stated in Telcordia publication GR-1089-CORE Electromagnetic

Compatibility and Electrical Safety Generic Criteria for Network Telecommunications

Equipment. The electromagnetic compatibility and electrical safety requirements for

equipment located in the outside plant (OSP/CELL-SITE), including customer premises are

primarily stated in Telcordia publication GR-3108-CORE, Generic Requirements for

Network Equipment in the Outside Plant.

Equipment Type

The equipment supplier shall determine the Equipment Type and record the appropriate

numerical equipment. To determine the Equipment Type, refer to GR-1089-CORE,

Appendix B for all equipment. GR-1089-CORE provides guidelines for applying the

aforementioned electromagnetic compatibility requirements. Application of the various

criteria is a function of the type of equipment under consideration, its connection to the

telecommunications network and the intended location of the equipment.

Electromagnetic Interference

A. Carrier Grade Equipment shall meet the radiated emission requirements stated in

section 3.2 of GR-1089-CORE.

B. Outside Plant/Cell Site Equipment shall meet the radiated emission requirements

stated in section 5.2.3 of GR-3108-CORE.

C. RF Transmitting Equipment. The use of radio frequency (RF) transmitting devices is

restricted in and adjacent to network equipment areas, including Carrier Communication

Space, Partitioned Network Space, and OSP/Cell site GR-3108 Class 1 CEV/HUT. Any

equipment which includes an RF transmitting device that will produce RF energy in

network equipment space shall be evaluated when any of the following conditions exist:

1. The equipment includes a radio frequency (RF) transmitter, strobe/flash, or arc

discharge device

2. The equipment is capable of transmitting any type of information wirelessly via radio

frequencies

3. The equipment includes an internal or external transmitting antenna

For each RF transmitting device which meets one or more of the above criteria, Form

RFTX (15.17) must be completed and submitted. See Paragraph 15.6 for further

explanation of this form.
