Megalink Lines

Megalink is Bell’s Integrated Services Digital Network-Primary Rate Interface (ISDN-PRI) service. Megalink service provides digital access between the Integrated Services Digital network (ISDN) compatible equipment at Customer's premises and Bell's public switched telephone network (PSTN) and is based on ISDN primary rate interface (PRI) standard as developed by the International Telegraph and Telephone Consultative Committee (ITTCC). Specifically, the Megalink Service is called a Megalink System Group (MSG) and provides a number of B-Channels in one or more DS1 accesses, under the control of a single D-channel or of multiple D-channels, served from the same central office switch and operating together as one large system terminating at the same address with a minimum of one working telephone number and billed to a single billing telephone number. Megalink Service is configured according to Bell Interface Document BID-0025, filed with and available from Industry Canada. Megalink is available in designated Bell serving areas and replaces analog circuits by routing calls that are multiplexed at 1.5 Mbps (DS-1 service) Note: DS-3 service access is a specialized digital service operating at 44.736 Mbps will appeal to clients interested in high-capacity access between their establishments and the serving wire centre. DS-3 service access includes three rate components. The principle of these components is the same as that of the current DS-1 access. Megalink DS-3 access must be demultiplexed (channelized) at both ends.
