E1 framed/unframed to RS-530 DCE/DTE converter, AC or DC power


This protocol converter provides an E1 interfaces and an RS530 interface enables framing E1 to RS530 interface conversion between E1 rate conversion and slot extraction functions. Framed mode, the user can extract the E1 time slots n * 64K (n≤31) data channel; unframed mode, the user can use the data channel rate of 2.048Mbps. Built-loop test equipment capabilities to facilitate the opening and routine maintenance works.
