2.8.2 Frame Relay and Internet Service Provisioning
The inherent flexibility of the integrated access system 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 IAD is used as a CLE (Customer Located Equipment) to provide a
wide-variety of voice and data services to a multi-tenant premises. The service provider can
now add Internet services and native Frame Relay services by simply installing a Frame Relay
server in the existing IAD as shown in Figure 2-23. There is no significant addition of new
hardware or fork-lifting of existing hardware 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 due to:
•
Savings in capital expenditure due to minimal hardware upgrades and ease of
provisioning. In addition, the remote management capabilities of the IAD and Frame
Relay server improve the quality of service delivered thereby lowering costs.
•
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.
