DATAPAC was Canada's packet switched X.25-equivalent data network. Operated first by Trans-Canada Telephone System, then Telecom Canada, then the Stentor Alliance, it finally reverted to Bell Canada when the Stentor Alliance was dissolved.
One of the uses of DATAPAC network was to transmit debit card transactions between retailers and the financial institutions (banks) through the Interac Direct Payment EFTPOS network. Some automatic teller machines also used the DATAPAC network.
It was also used to transmit lottery ticket numbers that are purchased by customers.
Types of connections
- DATAPAC 3101 Teletype (Ascii) connections, both dial and leased.
- DATAPAC 3201 connections were made by using leased line connections in a speciality financial industry code.
- DATAPAC 3000 X.25 connections
With the advent of lower-cost WAN technologies like IP/MPLS, the importance of DATAPAC diminished in the marketplace. Bell phased out support for DATAPAC, discontinuing the service at the end of 2009.
