Frame Relay and Internet Service Provisioning

The inherent flexibility of the IMACS platform and the versatility of the Frame Relay server are brought into synergy to provide significant savings to both the service provider and user. An IMACS is used as a CLE (Customer Located Equipment) to provide a wide-variety of voice and data services to a multi-tenant premise. The service provider can now add Internet services and native Frame Relay services by simply installing a Frame Relay server in the existing IMACS as shown in Figure 33. There is no significant addition of new hardware or replacing of existing platform or complicated provisioning schemes. The Frame Relay Server also provides a PVC backup feature, which the service provider can offer as a premium, uninterrupted service to a customer in case the primary link fails.

The cost benefits are realized by the service provider as a result of:

•The high density of logical Nx56/64K ports on the Frame relay server enables very efficient grooming and concentration of Nx56/64K Frame Relay connections to the service provider access links.

•Savings in capital expenditure due to minimal hardware upgrades and ease of provisioning. In addition, the remote management capabilities of the IMACS and Frame Relay server improve the quality of service delivered thereby lowering costs.
