PBXport Rackmount PBX Digital Hybrid User Guide JK Audio
Introduction PBXport will allow you to send and receive audio through your multiline PBX, ISDN or analog telephone. While this may seem like a simple task, the challenge is getting the best quality audio from such a limited audio path. What is a Digital Hybrid? The PBXport digital hybrid connects audio signals to and from the handset side of a telephone without the variations in quality found with analog hybrids.

All other Aux controls should be set for what you want to send to the phone line.
Operation Connecting Cables Although each application will require a slightly different setup, standard configuration is as follows: Handset cable - Connect the supplied RJ-22 handset cable between the jack marked "Phone" on the front or back of PBXport and to the handset jack on the base of your telephone. Handset - Connect your telephone handset to the RJ-22 jack on the front or back of the PBXport marked "Handset". You must keep a handset connected at all times, even when you are not using it.
Operation (continued) the Mix
Operation (continued) A-B-C Selector Switch Use this switch to select the correct type of handset microphone that your telephone uses. A=Electret, B=Carbon, C=Dynamic. Trial and error seems to work best in determining which handset type to use. Your PBXport will only function correctly if the handset type selector switch is in the correct position. This switch changes signal level, impedance, and wiring to accommodate the differences in handset microphone types.
Operation (continued) Optional Jumper Settings If your unit was purchased after December 2007, there are two jumpers located on the circuit board inside the PBXport that affect your incoming audio. The jumper at J10 allows you to completely disable both the handset microphone and speaker when the Online button is pressed. The factory default closed position disables only the handset microphone when the Online button is pressed. This will have no affect on normal telephone operation.
FAQs ? ! Will PBX Port work with my __________ PBX phone system? Probably yes. We have to say probably because the handset interface is proprietary and therefore can change from model to model. We have no way of predicting how a phone manufacturer will use the handset wires in the future. The three handset microphone types that we support, electret, dynamic, and carbon, cover every handset microphone type that we have seen in use, but the wire diagrams can change without notice.
FAQs ? ! ? ! ? ! How do I connect a call through PBXport? Every time I press the “Online” button, the call is disconnected. If you put the handset back in the cradle on the telephone, it will depress the hook flash button on the phone and your call will be disconnected. You should set the handset down beside the telephone and only return it to the cradle after your call is completed.
