pairs of subscriber lines.
The VX-connection module provides a connection point between an exchange-side
cable pair and a distribution pair. Itincorporates 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.
