In Bradford we have a number of PCT1. Some of these have a Siemens OTU to comminicate with the UTC system. Others have the Dynniq integral OTU built in to the CPU. Others we don’t have any communications at all. The first problem we were having was a licence error which was rectified by up grading the R8 firmware. The newer installs with the UG405 integral OTU are experciencing this “slow CPU” fault. These appear to be on installs with the R11 firmware installed within the cpu. The ones with the R8 upgrade are working fine within our wireless network. Dynniq seem to think it’s being caused by “network storming” so this is being looked into by our IT guys. Ian (
