AD 240 12/16 KHz Billing Pulse Generator

The ConceptThe AD240 Billing Pulse Generator is designed to locally produce 12 or 16 KHz billing pulses. It can generate billing pulses for up to 2000 prefixes (max 8. digits). The billing start can be triggered by either polarity reversal or by a DTMF tone.When is it needed? Enterprises using local call accounting and billing solutions that are dependent of the 12 or 16 KHz billing pulse services provided by national telecom carriers, will be unable to bill the calls sent via alternative carriers like ITSP since those carriers dont supply these billing pulses. For these cases, the AD240 can be integrated in their telecommunications system in order to produce the required billing pulses locally. The AD240 is a 4 port device that can generate billing pulses on 4 Trunk lines independently.How does it work? The AD 240 should be connected in serial between the PBX and the interconnection device(s) (gateway or auto dialer) on the CO lines.
