News Flashes
Christams Greetings
December 23, 2011
As the year draws to a close Alan Reedy, Bill Dawid, and Richard Brent wish you all a very Merry Christmas and Happy New Year.
Access Standards will be closed down from 24th December, and open again on 16th January 2011
Access Standards has moved
October 18, 2011
We have moved to a new address from the Tory Street Telecom Centre where we spent the past 10 years.
Our new address is:
L3 Gen-i Plaza
57-65 Manners Street
Wellington 6011
Our phone numbers remain the same, although at this point we do not have a fax machine, but will advise when this is connected.
Electronic Telepermit Applications
We now have no facilities for storing any paper based files, so it would be appreciated if all Telepermit Application documentation could be sent electronically either as email attachments, ftp sites or physically on CD or DVD.
Change to TNA134
September 22, 2011
A correction has been made to TNA134B4.pdf - Telecom ISDN User - Network Interface, Layer 3 - Part B: Basic Call Control Procedures (Section 4) . Table 4-12/B, which gives the coding for the Calling party number information element, shows coding (octet 3, bits 6 and 7) for the (caller ID) presentation indicator. The Telecom ISDN does not support this feature, and setting these bits will not be recognised by the network, and will not be generated by the network. If the Calling party number is to be withheld, the called party number should be prefixed by 0197, or where all Caller ID information is withheld as a subscription time option, then the number may be presented by prefixing the called party number with 0196. This is consistant with the procedure used by analogue phones connected to the PSTN.
Table 4-12/B has a note added to this effect.
"NOTE 2 - The Network does not accept or pass a Presentation Indicator set by customer CPE. Instead of the Network provided CLIR Service or CLIR Overide (0196) or CLIP Withhold (0197) code prefex dialling can be used."
Withdrawal of PTC103
August 5, 2011
Following some feed back from those involved in telecommunications wiring in residential premises, where the status of PTC103 was questioned, PTC103 has now been withdrawn as a code of practice for new installation work. The specification remains available on this website, but is only intended as an historical reference which may be useful in repair situations. It is strongly recommended that when repairs are being undertaken to legacy daisy chain wiring, either a home distributor or a Network Interface Device (NID) be installed between the ETP and the first BT jackpoint, thus bringing the installation into line with the TCF code of practice (see figure 14).
As neither the cabling nor the BT jackpoint used in PTC103 compliant installations are suitable for use in the TCF code, they should be left in place, as they are still adequate for telephony and voiceband data such as fax. By installing a home distributor or NID, they will be separated from the data cabling, and are still compatible with the BT plug terminated line cords which are supplied with most CPE.
For some time to come there will be a mixture of RJ45 and BT jackpoints in residential premises, and the corresponding uncertainty as to which type of line cord should be supplied with analogue CPE. The following possibilies are suggested.
- Supply analogue CPE with both types of line cord
- Supply one type of line cord and an adapter for the other type of jackpoint
- Supply the CPE and line cord of choice separately
Time for which Telepermit Holder Obligations remain valid
June 1, 2011
11.9 Continuing Obligation
Provided:
1. The product still meets the PTC requirements when the Telepermit was granted.2. There have been no network changes which would adversely affect the operation of the product.
3. The product is still being used by customers,
The obligations of the Telepermit Holder stated in clauses 11.1 to 11.8 shall remain for the reasonable life time of the product.
- The reasonable life time of a product would be generally the same as the time over which there is an onus to repair or service a product under the Consumer Guarantees Act 1993.
- Telecom may cancel a Telepermit for reasons set out in cluase 12.2. However PTC 100 and the Consumer Guarantess Act still apply to product which has already been sold.
Clocking PBXs from the PSTN
March 15, 2011
PBX installers are reminded that Customer Equipment (CE) must take its clocking or synchronising signals from the Public Switched Telephone Network (PSTN).
If the PBX is correctly set up so that it takes its synchronising signals from the PSTN then the PABX will in effect become part of the network and clocking glitches (slips) between the PBX and the PSTN will be eliminated.
This means the installer must set up the PBX to accept clocking pulses for the PBX from the incoming E1 stream; different PABX models may use different terminology such as:
- RX clock
- RX Timing
- Loopback
Currently the Telecom PSTN is experiencing 10,000 slips a month and they are all coming from DTLM (our local variety of E1) and PRA interfaces with PBXs. This can only be happening because installers have set the PBX to use its internal clock to synchronise its interfacing arrangements.

Notice of Telepermit Assessment fee increase
September 30, 2010
Our charges for Telepermit processing were last increased on 1 July 2003. While we have tried to keep fee increases to a minimum there is an inevitable point where we can no longer absorb our increased costs.
In the circumstances, we will be increasing our Telepermit processing charges from 1 January 2011. Our revised charging structure, inclusive of GST, will be as follows:-
| Current | New | |
| Assessment of CPE with single network interface e.g. PSTN, ISDN, ADSL2+ etc, inclusive of their power supplies, where applicable | $393.75 | $430 |
| Assessment of additional network interfaces for CPE with more than one different network interface | $393.75 | $430 |
| Assessment of additional products in a family, which can be assessed from one set of test reports, and are processesed at the same time. | $130.50 | $150 |
| Variations to products, product name changes, etc, for which no test reports have to be examined | $78.75 | $90 |
"Bulk changes" covering several products and part of the same request will be subject to a range of discounts depending on the number of products involved. The general aim is to charge according to the total amount of work we need to do
Telepermit applications received before 1 January 2011 will be processed at the current charge, but only if they have been sent with all the necessary submission information by that date.
Note that the additional charge related to the additional work involved in examining overseas test reports does NOT apply to electrical safety test reports (overseas test labs report to IEC 950 or IEC 60950, which apply also in New Zealand).
We will continue to provide our usual advisory service to Telepermit applicants at no cost, as we are happy to assist suppliers to meet our requirements in what ever way we can.
New Version of PTC285 published
June 2, 2010
PTC285, Requirements for VDSL2 Splitters, has been amended (iss 4) to include the option of a wire ended device without the weather proof encapsulation. This intended for use indoors rather than in the ETP. The electrical characteristics remain unchanged.
Replacement of Premises Wiring Code of practice (PTC106)
May 3, 2010
As the Code of Practice for customer premises is applicable to all carriers and service providers, it is appropriate that ongoing development of this document should be overseen by the Telecommunications Carriers' Forum (TCF). PTC106 (Star wiring Code of Practice) and PTC225 (Home Distributer) have therefore been withdrawn as Telecom documents, and are replaced by a single document TCF Premises Wiring Code of Practice : February 2010. This document may be obtained from the TCF website at: http://www.tcf.org.nz/premwiring

PTC 228 Draft Specification for SIP Trunking
December 23, 2009
A new network interface for PBXs will be trialled in the new year. This is an IP access using SIP signalling and is intended to compliment existing ISDN access, and possibly eventually replace it altogether. Features of the new service are that it gives direct access to the Telecom IP core, and includes gateways to the PSTN. The specification for SIP trunking is PTC228
Initially PTC testing will be carried out in the Telecom Network Integration Laboratory (NIL) in Tory Street Wellington, using a model VoIP/PSTN Network. We are currently working through the testing methodology, and hopefully we will be able to accredit external laboratories when we have a better feel for what is required.
