Installation and Commissioning of Media gateways SURPASS hiG 1200 for the Next Generation Network roll-out for Hutch-NLD network.

NGN Roll-Out Hutch NLD Network

The Hutch Network consisted of 2 Soft Switches SURPASS hiE 9200 located at Mumbai and Delhi and 23 Media Gateways SURPASS hiG 1200 located all across India. The MPLS backbone had 8 Tier-1 Locations on M40e on redundant model having VRRP as routing protocol and 15 edge Locations on M10i redundant model mapped onto VLAN s, residing over SDH.

Both the Soft switches work in Geo-Redundant mode and handle the traffic from all the Media Gateways in case of any of Switch failure. The NMS was co-located with Soft Switch.

The function of Core locations was to provide high bandwidth connectivity from lower Tier locations and connectivity between them. The objective of the Edge sites was to aggregate the traffic coming from the access location and uplink it to the core locations.
This dual architecture provides redundancy at - Hardware Level
Layer 3/ MPLS level MPLS-FRR

Creation of SS7 database and Interconnectivity testing with other basic and cellular Operators.
Subscriber, PBX and Centrex Data Administration.
X. 25 Link Administration for Remote file transfers.
LNP Local Number Portability Testing and Implementation Bharti Airtel Ltd
The proposed LNP system used Query on Release to route calls to ported DNs. This implementation of LNP was based on QOR as it would permit better load distribution between MSUs of a cluster serving same SDCA, also migration of subscribers from 1 MSU to the other. Further LNP based on QOR minimizes transiting of calls through Donor MSU.
A 4 digit LRN was proposed for all MSUs where LNP was implemented, the LRN was returned as a result of the LNP query and was used for routing the call to the destination MSU.
The LNP System comprised of LNP server, SSP, STP and NPAC.
Responsibility
Database Configuration of IN Trigger and SCCP Database at the MSU.
Database Configuration for Inter - MSU Number Portability, LNP Method Activation QOR.
