Meter Pulse Facility (BT Retail) CPA
31/10/2007 (Phase 1)
01/03/2008 (Phase 2)
01/09/2008 (Phase 3)
Proposed replacement product options:
Party Answer (line reversal)
Key customer benefits
Called Party Answer (CPA) is a line feature replacement that is compatible
with many types of CPE, e.g. call loggers, private payphones and small PBX's.
Some older CPE may need to be replaced when Meter Pulse Facility is withdrawn.
Key functionality changes
CPA only indicates when the called party has answered. It does not provide
subsequent metering information. Customers will need to check with their CPE
suppliers to see if it is compatible with CPA. Alternatively, there are
standalone CPE applications that do not require CPA. Loss of a low frequency
50Hz signal applied to both A/B wires simultaneously on a call part answer
signal. The call party answer (line reversal) signal is seen as a suitable
replacement as most CPE has the capability to work with both Meter Pulse
Facility and Called Party Answer signals.
