E1 module replacement

Discussion in 'Cisco' started by Francesco Rossi, Mar 14, 2007.

  1. Hi all,

    -- I'm in charge of replacing a CISCO box equipped with a NM-1CE1U card
    (DB15 connector).
    The box is connected to an E1 channellized line, 75ohm-unbalanced, BNC
    terminated (Network End).
    Moreover this box is 30 mt far from the telco network termination, so
    there'a a DB15M to dual BNC cabling from the box to the NE.
    -- Customer provides a new box equipped with a NM-1CE1T1PRI card (which is
    intended to replace the NM-1CE1U in cisco end of sale roadmap).
    This card connects through a RJ48C plug (if I remember well)....

    Now the questions are:
    How can I connect the box to telco line (in the less expensive manner)?
    Shall I use a RJ48 to BNC cable (balun ?) and replace DB15M with two BNC (on
    the 30 mt cable)?
    Is that the only way to accomplish this ? I wonder if there is a way to do
    this without having to modify the 30mt cable to Network Termination (eg.
    RJ48 to DB15F cable)....

    Thanks In Advance,
    FR
