1 General 1.1 Signalling Irregularities and Wrong Side Failures A signalling failure is termed an irregularity when vital signalling equipment items or circuits do not function correctly in accordance with their design specifications to provide the intended protection.
1.2 Reporting and Recording of Signalling Irregularities and Wrong Side Failures All irregularities and wrong side failures detected shall be reported to the Network Controller at the first instance detailing the incident and what actions have been taken to minimise any risks associated with the incident.
A large number of diseases are caused by defects in signalling pathways. The nature of these defects and how they are induced varies enormously. Pathogenic organisms and viruses, many of which can interfere with signalling events, can cause some of these defects.
Engineering (Signalling) Procedure ESM-00-03 Signalling Irregularities and Wrong Side Failures General It may be that a defect has been present for some time and has only come to attention under the circumstances of the irregularity incident.
