42 Enterasys X-Pedition 8000/8600 Getting Started Guide
SSR-HSSI-02-CK
The HSSI interface extends the benefits of the X-Pedition router to the WAN, providing
application-level control and wire-speed across high-speed WAN connections. The HSSI interface
supports PPP and Frame Relay at speeds up to 52 Mbps. Typical applications include T3/E3
circuits or inverse multiplexed T1 connections. Flow Rate Limiting, Weighted Random Early
Discard and Weighted Fair Queuing work together to manage and prevent congestion. The SSR-
HSSI-02-CK also provides external clocking—you do not need an external CSU/DSU.
The HSSI module for the X-Pedition supports true Layer 2, 3 and 4 switching, allowing for
consistent policy management for security and quality of service. Detailed accounting information
can be gathered using per-PVC RMON, enabling easy confirmation that service-level agreements
are being met. Prioritization policies can be extended across the entire network to allocate
appropriate resources to groups of users, or specific applications.
