The omission of these functions dramatically increases the throughput because each frame requires much less processing time. Benefits of Frame Relay Enterprise remote access solutions are composed of a variety of components, including technology, hardware, software, standards, and architecture to provide Frame Relay services within the enterprise environment. Examples of these components include data, voice over Frame Relay, Frame Relay multicast, IP multicast, and compression. Frame Relay technology poses fewer issues when covering longer distances for the remote user who is far from the central office (CO).
Cisco's internal remote access services are categorized as Cisco-managed, vendor-managed, and user-managed. The Cisco-managed services account for the Frame Relay, ISDN, and dialup services, where an internal Cisco IT team provided support for the end-to-end solution. The vendor-managed solution was an outsourced private DSL network where all support services were provided by the vendor. The user-managed solution was created for the internal VPN deployment, and it was a hybrid solution where end users managed the home connection with their selected ISP, and Cisco IT support managed the headend VPN concentrators.
Part I: Remote Access Fundamentals 35 36 Part I: Remote Access Fundamentals The T sector of the ITU-T is responsible for issuing protocols for the E-Series, I-Series, and Q-Series, and for components of the X-series that are related to ISDN, broadband ISDN (B-ISDN), and Signaling System 7 (SS7). E-Series protocols cover the standardization of the recommended telephone network for ISDN. 331), for example, defines the formats of ISDN addresses. I-Series protocols cover the standardization of concepts, terminology, and general methods.
