scope:

The requirements defined in this standard apply to the AzLM Axle Counter system manufactured by Thales and specifically to the Axle Counter cables that carry the ISDN signal from:

the EAK junction box or termination point to the EAK (star-quad);

the EAK to the ACE equipment (multi-twisted-pair).

Purpose

The aim of this standard is to clearly define to cable manufacturers the construction and performance requirements for AzLM Axle Counter cable. Manufacturers should therefore submit evidence intended to demonstrate compliance with this standard when seeking Network Rail Product Acceptance. It also provides background information to Signalling Designers, Signalling Installers and Signalling Maintainers.
