Possible Impact of Number Change on Pre-programmed Telecoms Equipment
Many subscribers will be informed of the 2006 Number Changes directly by their network service provider. From the commencement of parallel running in December 2005, callers will be able to reach customers in affected number change areas by dialing either the old or new number. New 7 digit local numbers should be dialled together with the STD code until the number changeover has occurred. At the end of parallel running, dialled calls to the old numbers will be routed to recorded announcements.
Some subscribers, both business and residential, will have telecommunications equipment which has a programmed telephone number in it, often referred to as a “Hidden Number”. Examples of equipment that have hidden numbers are listed below.
Customers who have this equipment should contact the supplier of this equipment to ensure that it will continue to function after number change-over. Providers of Telecommunications Equipment and Support Services should ensure that affected pre-programmed numbers in communications equipment for which they are responsible are changed to the new numbers.
It should be noted that for some areas the STD Code is also being changed and that communications equipment requiring reprogramming may not be confined to these affected areas.
In particular, the following equipment should be checked for pre-programmed numbers:
PABXs
Call Management Systems
Public Payphones
Customer Payphones
Alarm and Security dial-up units
Dial-up units for callout of fire and ambulance personnel
Credit card validation machines
Terminals for pre-paid top-ups and lotteries
Fax Machines
Personal Computers with dial-up modems
Phone memory diallers
Back-up data circuits using dial-up modems
For further information on the number changes please contact your telephone service provider.
