Network Termination Device (NTD)

A NTD (Network Termination Device) is device that can be installed to single dwellings or, in some cases, small business, and terminates a carriers (ie Telstra) lead in phone cable and becomes a defined network boundary point, customer cabling is then cabled from the NTD.

The NTD is housed in a light brown enclosure marked 'Telstra' and 'Network Termination Device' and has a line module for each active line which Telstras lead in cable terminates on one side and all the customer cabling on the other side and provides a socket for testing. The module may include a DSL central filter, or a separate filter may be mounted inside the enclosure.

Telstras responsibility is to maintain up to and including the network boundary, usually this is the 'first' socket in the house, however with the increasing not to standards 'star wiring' from a lead in cable, a 'first' socket or network boundary can be hard to find.

Advantages of a NTD

Who installs the NTD?

For new line connections, were Telstra are connecting a new lead in cable to a newly built dwelling, Telstra MAY, at there discretion, supply and install a NTD at no additional cost, providing the customer cabling has been pre wired from the NTD location to outlets inside at no cost to Telstra, the NTD location is approved by Telstra and Telstra are given prior notification of the requirement to install a NTD.

For new installations, the NTD can also be installed by a registered cabler authorized by Telstra, at the cost of the customer.

For excising installations, the NTD shall be installed by a registered cabler authorized by Telstra, at the cost of the customer.

At BJR Security we are authorized by Telstra to supply and install a NTD, under there specific requirements.

Please contact us for pricing on installation of a NTD.

Because the NTD becomes part of Telstras network, Telstra will maintain/repair a properly installed NTD and line modules for 'fair wear and tear' at no cost, at there discretion, no matter who installed the NTD in the first place.

Were would the NTD be located?

The NTD will be installed on the outside of the dwelling, were the lead conduit or aerial cabling enters the premises, usually at the front on the side, ideally near the electrical switchboard or earth stake.
You may already have a Telstra jointing box in that location, this is NOT an NTD and does not allow for customer access for testing.


Testing

If you are experiencing a fault with the phone line, either no dial tone, crackling or interference, cross talk or slow adsl speeds, you can test your line at the NTD and know if the problem exists on Telstras side, or cabling and or equipment within your premises which is not Telstras responsibility.

	Open main cover 1. Undo screw marked 'customer access' and remove locking/security seal cable tie underneath or lock if fitted. Note: you do not have to undo the top screw or cable tie marked 'Telco Access' 2. Release the tab above all screws, depressing finder on the tab from the side while opening the cover. The cover is hinged on the left hand side, so the cover will open from the right.
	Open line module cover to access test socket 3. Being careful not to disrupt any cabling, pull the tab on the cover of the line module indicated by the first arrow, pulling towards you, the cover is hinged on the right, so the cover will open from the left. Note: This NTD is equipped with a high quality C10 100P ADSL central filter that we installed.
	Connect test phone or modem 4. Connect a known working phone or modem into the test socket, this will disconnect ALL cabling and equipment within your premises, and connects straight onto Telstras lead in cable. If the problem still exists, try another phone to eliminate faulty phone or its lead. If the problem still exists, the fault is within Telstras network. Contact your service provider, this may be Telstra or another provider such as iprimus ect, and report a line fault, explain it had been tested at the NTD and is still faulty. If the problem has gone, the fault may lie within cabling or equipment on your side of the network boundary, which is not Telstras responsibility. Contact a registered cabler, such as us, for further testing and rectification. Note: You will need a self powered land line phone, as powered phones or cordless phone bases will require mains power to operate. To test a modem, you will require a long enough cable with an RJ12 style jack on the ends to run from the NTD to the modems location were it can be powered by mains power.
