  • Data rates up to 2.048 Mbps
  • 1U high enclosed chassis
  • Reversible cover with integrated mounting ears
  • Mounts in standard 19-in. (48.3 cm) rack
  • No AC power or batteries required

The Patton 450RC24 G.703 balun panel matches 24 sets of dual 75-ohm coax connections to 120-Ohm 50-pin telco connections. This feature allows network & datacom equipment manufacturers who are selling equipment for use in COs with only 120-Ohm telco interfaces to offer their equipment to G.703/G.703 countries using 75-ohm connections. This eliminates the mismatch with coax legacy equipment in many COs.

Model

Supporting E1 data rates to 2.048 Mbps, the Patton 450RC24 panel bi-directionally matches signal impedance and pulse shapes according to the CCITT G.703 standard. The Patton 450RC24 balun panel mounts in a standard 19-inch (48.3-cm) rack, occupies only 1U of rack space, and includes a reversible top cover.
