WAN solution for ERP application Client : A manufacturer of diversified products for construction industry located in Eastern India
Customer Requirement : • • • •
The customer wanted to establish WAN connectivity between the Central Location and 7 remote locations for ERP Application. The customer wanted to basically use the Leased line based network design primarily for implementing the ERP with auto ISDN backup connectivity. The customer wanted connectivity @ 64 Kbps speed. The connectivity and the distances are as follows: o Central Location to Remote Location 1 ( 30Km) o Central Location to Remote Location 2 (250Km) o Central Location to Remote Location 3 (>500km) o Central Location to Remote Location 4 (200Km) o Central Location to Remote Location 5 (40Km) And from Remote Location 5 there are two locations: o o
• • • •
Remote Location 5 to Remote Location 6 ( 9 Km) Remote Location 5 to Remote Location 7 ( 7 Km)
The customer wanted the Leased line based network design with auto ISDN backup connectivity primarily for implementing ERP Application with Data Transfer and VOICE connection at all locations. The customer wanted the connectivity to be always on. The customer wanted the Network Devices to be SNMP managed. The customer wanted provision for future scalability.
Summary of Dax Solution: Dax recommended leased line based connectivity solution with auto ISDN back-up for the customer. The recommended solution would give room for scalability at Central and remote locations for implementing EFP Application. In addition that, Dax provided dedicated VoIP Device for Voice Transmission. The solution is achieved by providing high-end router at the central location that is capable of catering all the 7 remote locations using appropriate modules for achieving 100% Data and Voice Transmission without any interruption.
The recommended WAN network setup is equipped for additional remote locations in future.

Details of the solution: Central Location: •
•
At the central location, Dax recommended one DX-2811 Security integrated Router with 2# 10/100 ports, 4 NM Slots. o One slot of the router was loaded with one 4-ports Sync/Async Serial Module (speed: 2 Mbps) and one 1-port Sync/Async Serial Module (speed: 2Mbps), to provide leased line connectivity to all the remote locations. o The balance two slots of the router was loaded with one 4-port ISDN U module and 1-port ISDN U module, so as to provide auto ISDN connectivity to all the remote locations when the primary line fails. Each lease line connection was designed to handle the line speed of 64 Kbps and in future up to 2 Mbps line speed.
At Central location For Voice: At the Central location, Dax recommended one DX-3504A FXS which is a four port telephone extension to IP network gateway. This provides telephone services and T.38 fax over IP network with easily operatable and configurable. It support DHCP
features for plug & play operation. By integrating with centralized GateKeeper or call manager, it provides full functions on voice/FAX services and office telephony services. It also supports phone-to-phone call and PC-to-Phone call if the softphone or NetMeeting is installed in the PC. It provides toll voice quality and FAX services under managed network i.e. VPN or Public Internet Network. Remote Location 5: •
At Remote Location 5, Dax recommended one DX-2801 Security integrated Router with 2#10/100 ports, 4 NM Slots, one console port, 85~95 Kpps performance, 8MB Flash upgradeable to 72Mb and 128MB SDRAM upgradeable to 256MB, Hardware IPSEC DES/3DES/AES inbuilt. o One slot of the router was loaded with one 2-ports Sync/Async Serial Module (speed: 2 Mbps) and one 1-port Sync/Async Serial Module (speed: 2Mbps), to provide leased line connectivity to all the remote locations. o The balance two slots of the router was loaded with one 4-port ISDN U module, so as to provide auto ISDN connectivity to all the remote locations when the primary line fails. o One slot was left free for future expansion.
Remote Locations: •
At each of the remote locations, Dax recommend one DX-1821 Modular Router with 2#10/100 port, 1 # fixed high-speed synchronous / Asynchronous serial interface, 1 WAN Slot for WAN module, and 1 # dedicated VoIP Slot.
This router has: • •
One fixed Sync/Async Serial Module (speed: 2Mbps), is used to provide leased line connectivity to all the remote locations. One unpopulated slot of the router would be loaded with one 1-Port ISDN S/T WAN Interface Module, so as to provide ISDN connectivity to all the remote locations.
At Remote Locations - For Voice: At each remote location, Dax recommended DX-3502A FXS which is a two-port telephone extension to IP network gateway. It provides telephone services and T.38 fax over IP network with easily operatable and configurable. Support DHCP features for Plug & Play operation. Provides VoIP and FoIP services to Home, SOHO and IP telephony call. DX-3502A provides Voice over IP and FAX over IP services for ITSP / ISP Internet Telephony Services Provider and Office / SOHO IP-PBX application. By integrating with centralized Gatekeeper or call manager, it provides full functions on voice/FAX services and office telephony services. It also supports phone-tophone call and PC-toPhone call if the soft phone or NetMeeting is installed in the PC. It provides toll voice quality and FAX services under managed network i.e. VPN or Public Internet Network.
Highlights of the solution: Cost-Effective Solution • • • •
At the remote branch router 1 wan slot was fixed which is a Sync/Async port. This could be used to connect leased line. This offers less investment and high performance. Each remote location would get dedicated bandwidth of 64 Kbps which could upgrade upto 2 Mbps in future. Future Expansion is possible without disturbing the existing setup. WAN optimization features such as dial-on-demand routing (DDR), bandwidthon-demand (BOD), compression, filtering, and spoofing to reduce WAN costs are supported by the central router DX-2811.
High Performance •
•
Driven by a powerful CPU processor MPC8245 @ 266 MHz speed, the DX-2811 Router provides a routing speed of up to 100~110 Kpps to support advanced QoS, security, and network integration features that are required in today’s evolving networks. Driven by a powerful CPU processor MPC8250, 200MHz speed, the DX-1821 Router supports routing speed of up to 40Kpps providing advanced QoS, security, and network integration features that would be required in today’s evolving networks.
Security and Reliability •
DX-2811 router employs hardware encryption and DX-2811, DX-2801 and Dx1821 supports IPsec and multiple protocols (such as L2TP and GRE) and to guarantee comprehensive network security service as well as network performance.
