Austin Taylor NTU Overview

Austin Taylor NTU

NTE5 / CTE5

Austin Taylor is a BT licensed manufacturer of the NTE5.
The NTE5 is fitted inside customer premises and provides a demarcation point between network and consumer wiring.

Using a removable lower cover, consumer extension wiring can be easily isolated from the telephone network facilitating easy fault location.

The NTE5 is supplied fully mastered i.e. full PSTN master.

The NTE5A is designed to terminate networks using heavy drop wire which is connected to two heavy duty screw terminals.

Extension telephone wiring is connected to iDC contacts housed in the lower consumer access cover and, on removal of the cover, can be easily isolated for test purposes.

Removing the consumer access cover also exposes the test socket which is used to determine whether a fault lies in the telephone or the customer wiring.
When the lower cover is replaced, gold plated contacts connect the customer wiring to the network.

The CTE5 is a variant of the NTE5 designed for use on networks using standard telephony wiring or Siamese cables. The network wiring is connected to a 3 way IDC (NB: maximum conductor diameter 0.65mm)
