Rj-2Nx I/O Module; Specifications - Cisco VCO/4K Mechanical Assemblies

4.0 RJ-2nX I/O Module

There are four types of RJ-2nX I/O modules with different pin assignments depending on the
transmission and signal type of the E&M card. The four types are RJ-2EX, RJ-2FX, RJ-2GX,
and RJ-2HX. A single RJ-2nX I/O module is tied to a single E&M card. RJ-2EX, RJ-2FX, and
RJ-2GX I/O modules carry all required connections from the respective backplane connector to
a single 25 pair RJ-21 type connector. The RJ-2HX I/O module requires two 25-pair connectors.
The analog plug-in I/O modules optimize standard 25-pair MDF cables. Use one 25-pair
telephone standard cable to connect each analog I/O module on the VCO/4K to a block on the
MDF. Specify the RJ-2nX I/O module according to the number and type of cards.
