The CD10 is associated with a PBX (Private Branch Exchange) to provide trunk to trunk call forwarding. If the PBX is equipped with inward toll free 800 numbers, employees at remote locations can place all calls through the PBX with all billing to the home office. It provides voice response and password protection.
The CD10 connects to a PBX analog station line. Since the PBX is used as the transfer medium, the CD10 is ready to receive another call as soon as the transfer completes. If the PBX is equipped with digital facilities, there is no transmission loss as compared to call diverters that bridge 2 lines.
All password and call processing is accomplished using touch tones. Trunk access codes that are always dialed can be globally set to automatically precede the dial sequence. Local and toll call access have separate passwords. A caller that has been given the local password can only make local calls from the PBX location. A caller that has been given the toll password can make local or toll calls from the PBX location. Passwords and numbers must be entered within 30 seconds. A "*" in the dial string causes a 1 second delay.
