Suppliers' Information Notes are produced to meet BT's regulatory obligations that relate to the publication of Customer Interface information. To this end, BT has agreed with Ofcom that SINs will be used to provide information about its network offerings. This may be the launch of a completely new service, or it may be the addition of new features within an existing service. Withdrawal of services or facilities will also be announced through SINs.
