The coax to RJ45 16E1 balun converter allow 75 Ohm coax to communicate with 120 Ohm twisted pair equipment. The 16E1 balun panel specifically address the ONP requirement that PTTs offer 120 Ohm twisted pair terminations to their customers. Some telecommunication equipments output only on 75 Ohm coax,or have customers whose CPE has only 75 Ohm coax connections. The 75 ohm to 120 ohm balun panel present a ready solution to this termination mismatch by allowing a bi-directional conversion of coax(75 Ohm )to a twisted pair (120 Ohm ),supporting data rates to E1(2.048Mbps). The signals output by them are scaled to match the pulse shape requirements specified by the CCITT G.703 standard.
