Yesterday, frequent transmission errors were seen between the SUS-ITMY and ISI-ITMY models (6 errors per second once every 10 minutes). 150errors/s was authorized by the ISI model before tripping the ISI watchdogs. A similar issue is seen with the IOP models. However, transmission error are less frequent (6 times 1error/sec (on a 64K model) during a 15h period - cf attachment). Consequently, the measurements initiated last night didn't go through.
