Leased Line is the traditional point-to-point, dedicated TDM circuit that is built on the SDH transport technology. It provides choice of bandwidths, ranging from 64 Kbps to 155 Mbps (STM1) and multiples thereof.
The Leased Line service is built on a network that is architected to provide dual path (ring) protection in the access and edge segments, unlike most traditional networks that are single path. In the core segment, due to the large perimeter of the rings, the protection is made even more robust with a multi-path protection mechanism. The result is that enterprises get a higher uptime on their leased lines than they ever got in the past. The service is further supplemented with SLAs for uptime and for time taken to restore the service in the rare occurrence of a service degradation or a failure. The SLA performance reporting is proactive and available to the enterprise administrator online as opposed to the current practice that requires enterprises to manually administer SLA achievements of the service provider and report violations to the service provider later.
Enterprises can opt for the appropriate flavor of the Leased Line Service for connecting key nodal locations such as the data centres, corporate offices, DR sites, call centres among others, on dedicated links.

‘Over-the-wire’ bandwidth upgrades cumbersome physical provisioning for bandwidth upgrades is history; all it takes to increase bandwidth is a call to upgrade the bandwidth. 64 kbps to E1 – without change of modem, E3 to STM1 – Over the same fibre & SDH MUX.
Enterprises having a central location that connects to multiple sites via different leased lines can leverage the bandwidth aggregation feature to realize cost savings. Point to multipoint links < E1 can be aggregated into a single E1/E3/STM-1 interface that significantly reduces the number of router ports and associated management complexity.
