Wiring from the IDCs of the customer connection unit of a NTE-5 (A or B)* may be daisy-chained or star wired or a mixture of both.
The problem arises when a NTE-5 is fitted to an already star wired set-up, so that when the customer connection unit is removed and the test socket exposed, other sockets remain connected.
When a NTE-5 is fitted it should always be wired so that all extensions are connected to the IDC's of the customer connection unit so that when the test socket is exposed there is a dial tone at the test socket and nowhere else.
As far as Broadband is concerned, a filter faceplate on the NTE-5 is the way to go.
* A or B in this case refers to the type of NTE, not the A and B terminals.
