чем отличается rj 45 от rj 48c

To connect a Bridge or Router to a 56K, CSU/DSU Network, T3, T1 or Fractional T1 line, use a cable with an RJ-48S jack connector.The RJ-48 connector may look very similar to an RJ-45 connector found on a typical CAT-5 cable, but don t be fooled, they are very different in many ways.A RJ-48 connecter is fastened on to a STP (Shielded Twisted Pair) cable, not the standard UTP (Unshielded Twisted Pair) CAT-(1-5) cable.A RJ-48 also uses a different pin out arrangement, voltage level, and line capacitance then a RJ-45.See below for details on the RJ-48C, and RJ-48X connectors.
