Your right GR-1089 is not a legal requirement. But if you want to sell your product to companies like Verizon you MUST meet NEBS requirements which includes GR-1089. It is not legally required, but they will tell you they are not required to buy products, or allow co-location of products that are not compliant with their standards.

The way I used to specify the test plans were to complete the emissions tests with 'doors open' and 'doors closed'. This would allow the GR1089 criteria to be met and also the FCC criteria to be met. I know that it means repeating certain test frequency ranges but the FCC tests must be met for almost all carriers. GR1089 is not a legal requirement, it is good to meet it (especially with Verizon or to co-locate with Verizon) but the FCC is a regulatory requirement and is good to have to sell in other market areas. An example of what I mean is shown below. [1] E-Field - Enc. (Doors Closed) GR-1089-CORE R3-1[8] 10k to 30M Class A E-Field - Enc. (Doors Closed) FCC part 15, EN55022, GR1089-CORE R3-1[8] 30M to 1G Class A E-Field - Enc. (Doors Closed) FCC part 15, GR-1089-CORE R3-1[8] 1G to 10G Class A E-Field - Enc. (Doors Open) GR-1089-CORE R3-3[10] 10k to 30M Class A E-Field - Enc. (Doors Open) GR-1089-CORE R3-3[10] 30M to 10G Class A H-Field - Enc. (Doors Open) GR-1089-CORE R3-4[11] 60hz to 30M Class A [1] H-Field - Enc. (Doors Closed) GR-1089-CORE R3-1[8] 60Hz to 30M Class A [1] perform doors closed only if doors open criteria is not met.

It also has limits for below 30MHz and above 1GHz. This section I understand. What I don't understand clearly is requirement R3-3 [10]. It references emissions from Class A and B unit's not exceeding Table 3-2. Table 3-2 limits are higher than the FCC Class A and B limits. The doors or covers are to be opened during emission testing. However, if the doors and covers that are not intended to be opened during EUT operation, maintenance, and/or repair need not be opened, I can still test to those higher limits. If so, I can no longer can be considered FCC A or B equipment. Is requirement R3-3 [10] mainly for central office areas and not residential? Thanks.
