Wire Connection Module

The Subscriber Terminal Block module provide 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 of both sides of the network.

1. Outdoor connections where the enviromental conditions are extremely agressive.
2. Terminations where user development characteristics require future flexibility in terms of the type of protection or filtering capabilities.
