The customer also required LAN connectivity in Bhat office with reference to an upcoming 50 seat Call centre. The IP based network was meant for Voice and data application. 2 Mbps bandwidth was required for the WAN connectivity. The customer also preferred the WAN connectivity to be always-on with auto ISDN backup connectivity, in case the primary leased line link failed. The customer required SNMP management option in these devices. The customer preferred the connectivity to be always-on. Summary of Dax solution: Dax recommended an IP based interconnectivity solution, which could be used for Voice and data application. At both the Mumbai and Bhat offices, Dax recommended the customer to opt for Modular Access router with multi WAN Slots to provide leased line as well as auto ISDN back-up connectivity to Mumbai office. For VoIP connectivity, Dax recommended 1 no of 2-port FXS Gate way in the Mumbai office and 1 no of 2-port FXS Gate way in Bhat office, thereby ensuring 2 concurrent voice channels. At the Mumbai office and the Bhat offices, the routers and VoIP devices were recommended vide the existing LAN switch. For the call center connectivity at the Bhat office to connect 50 nodes, Dax recommended 3 nos of 24-port 10/100Mbps layer 2 managed switches with Enhanced Cat-5 cabling solutions. To enable the outbound voice calls, Dax recommended server based ISDN PRI cum R2 multi-purpose RAS solution.
Typical connectivity setup in a Call Centre Details of Dax solution: Mumbai and Bhat offices: Dax recommended the customer to opt for Dax Maipu DXMP-1700 Modular access router, which has 4 WAN slots. The first slot of the router was recommended to be loaded with 1 # one port sync/async module to provide connectivity to another location. Second slot was recommended to be loaded with 1 # one port ISDN module to provide auto ISDN back-up connectivity, if the primary link fails. For VoIP connectivity, Dax recommended 1 no of 2-port FXS Gate way in the Mumbai office and 1 2-port FXS Gate way in Bhat office, thereby ensuring 2 concurrent voice channels. At the Mumbai office and the Bhat offices, the router and VoIP devices were recommended to be connected vide existing LAN switch.
For the call center connectivity at Bhat office, Dax recommended structured cabling network with 3 nos of Dax Megastack switches. Dax Megastack is an enhanced Layer 2 24-port SNMP manageable, stackable switch with 2 uplink modules supporting a variety of uplink options. To enable the outbound calls, Dax recommended Dax Eicon Diva PRI 30M multi-purpose IVRS RAS that allows as many as 30 concurrent voice calls, analog as well as ISDN. This powerful IVRS solution was recommended to be integrated in the IVR server as needed. The required Call centre software may be developed in line with 30M features and highlights. For an easy facilitation of this software integration, the SDK (Software Development Tool Kit) provided along with Dax Eicon DIVA Server PRI-30M comes in handy. The 30M RAS connects to ISDN PRI as well as E1/R2 lines and needs a pair of 2 Mbps G.703 interface Leased Line modems for termination. Highlights of WAN connectivity: Redundancy: The connectivity from the Central location to the Remote location is through a leased line link with an auto ISDN backup. If the leased line fails, the back up would automatically initiate the connection and maintain the uptime. When the leased line is restored, the ISDN back-up connection will disconnect automatically.
