Reliance Leased Line Advantages

Leased Line, the traditional point-to-point, dedicated TDM circuit, which is built on the SDH transport technology provides the option for choosing bandwidths, ranging from 64 Kbps to 155 Mbps (STM1) and multiples thereof. Unlike other traditional networks providing single path Reliance leased line provide dual path (ring) protection in the access and edge segments. Due to the large perimeter of the rings in the core segment there is a multi path protection mechanism which is safer. As a result of this the enterprises get a higher uptime in their leased line. For uptime and time taken to restore the service in the rare occurrence of a service degradation or a failure it is provided with SLA’s. The SLA performance reporting is pro active and and available to the enterprise administrator online unlike the current practice that requires enterprises to manually administer SLA achievements of the service provider and report violations to the service provider later.

There is an option for the enterprises to choose the appropriate leased line service for connecting key nodal locations such as the data centres, corporate offices, DR sites, call centres among others, on dedicated links.

Reliance Leased Line reaches 200 cities and is still developing. Also reach Delivery Media- Fibre, Electronics to the building Wireless Broadband LMDS-Microwave-based access for buildings not yet connected on fibre.

Scalability

N x 64 Kbps, 2 Mbps (E1), 34 Mbps (E3), 45 Mbps (DS3), 155 Mbps (STM1).

Flexibility

Choice of framed & unframed links
Interfaces available-G.703, V.35, Optical

Reliability

Last mile reduced to few feet of CAT 5 cable.

Electronics mostly placed in enterprise buildings
Access Network based on ring.
Meshed Core Network – More than 2 alternate paths

End-to-end SLA

Single point responsibility including local leads at both ends
High service availability up to 99.9%
Requirement of fewer CPE’s
None for G.703 interface (up to E1
Two for V.35 interface (up to E1)
Bundled CPEs – capex savings

Performance Reports

The performance reports on SLA parameters along with an online web-based view (CNM portal) of the enterprise leased line network is accessible through internet by designated users or enterprise administrators.

Unlike the past here 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.

Bandwidth Aggregation

Enterprises with central location, which connects to multiple sites via different leased lines can leverage the bandwidth aggregation feature to realize cost savings. Here the number of router ports and associated management complexity is less as the Point to multipoint links < E1 can be aggregated into a single E1/E3/STM-1 interface.
