Hi, Looking for information on the subject PBX. What gender are the connectors on the rear of the PBX for analog station. Amphenol 25p ? If I were to purchase a cable for this system what gender would my cable need to be to connect to it. Also, does the system use use 24 ports or is there a mixture, 8,12,16 and 24. Any assistance would be appreciated. Thanks in advance.
