3. Introduction
• Airtel is an offspring of Bharti Airtel Limited,
one of Asia’s leading integrated telecom
service providers.
• Bharti Airtel since its start,has been at the
forefront of technology and has pioneered
Several innovations in the telecom sector
• Founder-Sri.sunil Mittal

4. Airtel Positions
Airtel company redefined the way cellular
services being marketed in the country, was
made possible due to its innovative marketing
strategies,continuous technological up
gradations,new value added service offerings
and efficient customer service.

5. MANAGED PRIVATE LEASED LINE
• Managed private leased line is a unique pay-per-use
IPLC service offered exclusively to International BPOs
• This service provides the facility to make inbound or
outbound calls to multiple international destinations
over an end-to-end clear channel TDM connectivity.
• This service allows you to move existing International
BPOs from a conventional Capex driven to a flexible
Opex driven network environment. The added
advantages are scalability and reliability for
international connectivity.

6. What you get
• Inbound calling services from USA DID/ USA Toll Free/ UK toll free numbers
• Outbound calling services to Australia, Canada, China, France, Germany, Hong
Kong, Malaysia, Philippines, Saudi Arabia, Singapore, UAE, UK and USA
How it benefits you
• End-to-end solution and ownership (including local loop, National Leg,
International Leg, switching and multiplexing, Call termination outside India
• Highly scalable and robust network architecture
• End-to-end clear channel TDM connectivity with no voice compression
• Multiple country call termination for inbound and outbound voice traffic
• No man power requirement at USA/ UK etc
• Customer billing done on 1/1 pulse rate

7. Airtel's backbone is divided into three tiers
• Tier 1: These are set of Core ISP PoPs of Airtel and are in 5 different
locations viz Chennai, Mumbai, Bangalore, Hyderabad and Delhi. These
POPs are directly connected to Airtel's dual Internet Gateways in
Chennai on N x STM1/ N x STM4 circuits. Redundancy is provided in
the backbone for higher uptimes and low resolution time.
• Tier 2: These are set of PoPs directly interfaced with the core PoPs. Tier
2 Airtel IP POPs are directly connected to Airtel's dual Internet
Gateways in Chennai on N x DS3/ N x STM1 circuits.
• Tier 3: These PoPs are directly interfaced to International gateway
through the MPLS backbone. However, only default routes will be
available through these PoPs

9. MPLS NETWORK ARCHITECTURE
The global MPLS backbone is capable of
carrying any type of data (i.e. voice,
video, CRM, ERP, FTP etc.) across the
globe. With coverage in more than 70
countries and 700 cities, our MPLS
network is the right choice for managing
your Global WAN connectivity
requirements

10. • Layer 3 Global MPLS service specifications:
• Highly scalable and redundant backbone architecture
• No quick fix using existing ATM and frames
• Separate MPLS and Internet backbone
• Support of any-to-any meshed connectivity
• Support on variety of CE-PE routing protocol like Static, OSPF
and BGP
• Support of multiple class of services
• Flexible physical access port ranging from T1/ E1, DS3, STM1
to FE
• Flexible port speed ranging from 64 Kbps to STM1 level
• End-to-end CPE management and monitoring services
• 24x7x365 central NOC and support team
• Service level guarantee provided on uptime, availability,
latency, packet loss and jitter (for voice traffic only)

11. • Layer 2 Global MPLS
• Coverage in major geographies like Hong
Kong, Singapore, UK and USA
• Backbone network build on Cisco AToM (Any
Transport on MPLS)
• Support of point-to-point and point-to-
multipoint architecture
• Support of single class of service
• Scalable and redundant backbone architecture
• Access supported is on Ethernet
• SLA provided on availability, latency and
packet class

12. Managed Services Definition
• The managed services market is poised for expansive growth. The network
is becoming an integrated, intelligent platform for IT as customers
increasingly seek greater breadth of service, personalization, and quality
of experience. At the same time, emerging technologies,collaboration,and
globalization are promoting network complexity and management
demands that fall outside the core business of many end users.
• This programme being a CISCO certified programme, has been defined by
CISCO as follows:
 CPE used for the service is actively monitored and can be remotely
monitored and configured from the providers network operations
center (NOC), allowing the provider to troubleshoot errors in real
time.
 CPE title held by Partner or End Customer (in this case Bharti Airtel
is the partner)
 Service is always sold with an SLA that clearly lays out the
providers service and support responsibility to the customer.
 Provides scalability to customers.

14. How MSCP differs from SI program
• Cisco has traditionally had two distinct and popular
type of partnerships.
• The first one was the Distributorship and second one
was the Systems Integrator partnership.
• The Distributor model is a stock and sale model where
the support services are purchased by the customers
from a CISCO authorized service providers.
• The System Integrator partners sell CISCO equipment
as a part of a total solution and therefore do not stock
and sell.
• They also provide support services directly to their
customers. The Managed Services partnership is a new
initiative from CISCO to include service poviders who
have network ownership and network services
capabilities.

15. As shown in the diagram below SI program allows Service
provider to offer its specialization and support infrastructure
to attain the ultimate goal of customer satisfaction.

16. WHAT IS FLEXI CONNECT RAPVN
• Flexi-Connect is a remote access IP VPN service that provides cost
effective network to remote users like telecommuters, mobile work
force, warehouses in remote locations. It allows users to access
Enterprise VPN using different access technologies.
• This service is useful when the bandwidth usage is low or the last
mile cost over leased lines is prohibitively huge or the location is
too remote to be connected on any medium on a cost effective
basis or customer has a mobile requirement.
• Flexi-Connect service provides flexibility of logging into secure
MPLS network through a wide range of access technologies. All
corporates adopting Flexi-Connect would have the options to
connect through following connectivity options
 PSTN Dial-up
 ISDN BRI Dial-up
 Internet

17. FLEXI CONNECT RAPVN

18. How it works
• A roaming user can use any Land line (PSTN/ ISDN Dial-up) from any
service provider (including Airtel) to dial the nearest dial-in numbers
available depending upon the location.
• The Remote Access Servers would be placed in 6 geographically separate
locations in India namely Delhi, Mumbai, Bangalore, Chennai, Hyderabad
and Kolkata.
• Authentication traffic will be carried to central location at Delhi using L2TP.
• Post successful authentication user will be allowed access to the
enterprise VPN. CHAP and PAP features are supported
• IPSec/ SSL PE, AAA Servers, LNS etc: All such servers are placed the MPLS
network.
• Internet customers: All Internet customers would be offered two means of
service security a. SSL thus allowing client less access b. IPSec
• Flexi-Connect product supplements our existing MPLS based VPN service
offering. Multi-protocol Label Switching (MPLS) of Airtel is a versatile
solution to address the problems faced by networks -speed, scalability,
quality-of-service (QoS) management, and traffic engineering.
