8. Railtel’s Network & Plan
• Focus on long distance band-width
• Build nation-wide OFC network of 45,000 Route KMs OFC
connecting 4,000 stations using STM16/DWDM
• 28,000 RKM of STM 16 network in place in multiple layers
(Backbone Layer), Multiple Self healing rings with Multi
service SDH systems
• Edge (at 40-50 Kms PoP) of STM 4 and Access layer ( at
every Station) of STM1 with Ethernet Interfaces
• All station equipped with 155 Mbps BW& 10/100 Mbps
ethernet ports
• DWDM 10500 KM implemented and another 12500 KM under
implementation
• NGN based NLD network in 18 cities (15 Circles) implemented
and another 36 cities under implementation
• Expansion of MPLS VPN Network from 40 cities to 81 cities.
• Local Access Network (OFC/WiFi/WiMAX) in 150+ cities
• Managed Telecom Services on Railway towers
9. DWDM
STM-16 (2.5 GBPS)
Stns of commercial importance
STM-4/16 Imp. Stns 50-60 kms
STM-1/4 Every stn 8-10 kms
10/100 MBPS
Ethernet
OFC SYSTEM CONFIGURATION
10. Last Mile/ Access Network
• 1000+ microwave towers
• More than 3400 OFC POPs functional
• Co-location facility at all OFC POPs
• Deploying 100 cities MAN network either by
swapping fibre or building own OFC network
• OFC connectivity to MSC and BSCs of
service providers in 100 cities.
12. Why RailTel – Choice of Telcos
• 65000 Kms of Secure and Seamless ROW of Indian Railways
– ROW passes through central business districts of cities
– Readymade Infrastructure
• Huge Bandwidth
• Pan India Coverage
– Extensive Rural Coverage
• Access to physical infrastructure like office space, Power
Supply and Human Resource
• Existing Network Transferred From Indian Railways
• No Burden Of Legacy Network- Network State Of The Art
13. Why RailTel – Choice of Telcos
• Low Cost of Maintenance and availability of Manpower for the
same by leveraging the relationships with Indian Railways
• Lower Operational Cost through Economies of Scale and
choice of technology ( IP- based Technology)
• Experience in operating Telecom Network
• Better Quality due to Intrinsic Strength in Operation and
Maintenance. Quick Customer support (due to Railway’s
excellent work culture)
• Demand for redundancy due to never ending road expansion
by NHAI
• Fast Speed in rolling out network
• Neutral Player
RailTel’s USP- Delete Inconvenience, Insert
Delight
15. MPLS-IP Backbone
• Country wide IP backbone
• Routers- 40 locations covers
– metros,
– mini metros and
– other important cities of the country.
• Services to be offered
– MPLS IP –VPNs
– Layer 2 VPNs
– Bandwidth on demand
– Corporate leased lines
– VOIP
– Internet Bandwidth Services
– Managed network services
– Unified messaging services
• Extend IP services to 3400 POPs on SDH network
16. MPLS-IP Backbone (contd)
• Network Architecture
– Simple to implement
– Scalable as demand grows
– Flexible to accommodate complex
customer requirements
– Capable of offering full gamut of IP VPN
services
– IP V6 ready
17. MPLS-IP Backbone (contd)
• Network Topology consists of
– High end Core routers (4)- M20 of Juniper
– Core routers (9)- M 20 of Juniper
– Core routers connected in mesh topology using
STM 1 connectivity (being upgraded to GBE )
– Edge routers (25)- M 10 of Juniper
– Edge locations (25) dual homed into one or more
core locations over 100 MBPS Ethernet links
– 3000 POPs connected to MPLS backbone on
ethernet over SDH
