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.
