Tyco VX-MD five-point connection module,1 pair STB  Subscriber terminal blocks

     Hongyi Telecom Provide 1 pair subscriber terminal block series solutions. in cluding terminal box and interminal block types.The VX- MD connection module provides a connection point between an exchange-side

cable pair and a distribution pair. It incorporates a 5-point plug in module to provide continuity and a range of other options. Removal of the plug-in module does not disturb wire connections but makes contacts to them

available for testing to both sides of the network.

     It is especially recommended for

• outdoor connections where the environmental conditions are extremely aggressive,

• terminations where user development characteristics require future flexibility in terms of the type of protection or filtering capabilities.
