The OpenVox timing cable ACC0001 is a standard two pin jumper cable. It allows Analog cards and T1/E1 cards to share the same sync (timing) source from the T1/E1 line provider,?or?provide a consistent sync source across multiple cards. This is a useful feature for data and fax modes and some voice applications to prevent corruption due to timing slips on multiple cards in the same system. And thus the timing cable enables OpenVox users to experience superior quality fax service.
