PD 7002:1996
Withdrawn
A Withdrawn Standard is one, which is removed from sale, and its unique number can no longer be used. The Standard can be withdrawn and not replaced, or it can be withdrawn and replaced by a Standard with a different number.
Essential requirements for connection of terminal equipment to 2-wire analogue interfaces, without capacitive termination, of public switched telecommunication networks using either the earth calling, the loop calling-disconnect clearing, the loop calling-guarded clearing or the loop calling-unguarded clearing signalling method
