Note: In the PLID column, n represents the unit number: LX is 2 - 5.. The LS Ring/Tip 1-n
connections are used in the UK for Meter Pulse Detection (MPD). These ports should be
wired across the corresponding LS Ring/Tip connection of the trunk. We recommend that
the MPD connections are made at the last hard wired point.
