Only measurements of the pilot level are made on international group, supergroup,etc.links.These do not involve other stations. Therefore,Administrations are free to decide on the methods and periodicities.In order to ensure that the performance limits of the links laid down in Recommendation M.160 are met,the following tests are recommended for consideration.

ITU-T M.530-1988 对一个国际集团超群等环节的标称值调整.研究组4

Test frequencies for supermastergroups are not shifted at f 80 Hz,as they are located in wide guard intervals and do not coincide with carrier leaks and pilot frequencies.Test frequencies 9008 kHz,11 096 kHz and 11 648 kHz given in Recommendation M.460 should be shifted to avoid interferences between supermastergroup and mastergroup No.7 and No.9 pilot frequencies (see Recommendation M.350)
