Chapter 2 Card Reference

CE-100T-8 Card

Each 10/100 Ethernet port can be mapped to an SDH channel in increments of VC12 or VC3 granularity. There are eight backend packet-over-SDH (POS) ports (VCAT groups [VCGs]) available on the ML-100T-8 card. Additionally, the CE-100T-8 card supports packet processing, classification, quality of service (QoS)-based queuing, and traffic scheduling.

The following paragraphs describe the general functions of the CE-100T-8 card and relate it to the block diagram in Figure 2-3.

In the ingress direction (Ethernet-to-SDH), an octal PHY, which performs all of the physical layer interface functions for 10/100-Mbps Ethernet, sends the frame to the packet processor for queuing in the respective packet buffer memory. The packet processor performs packet processing, packet switching, and classification. The Ethernet frames are then passed over SMII channels to the POS mappers, where Ethernet traffic is terminated and is encapsulated using the PPP/HDLC or GFP framing protocols. The encapsulation method is selected on a per-port basis. The encapsulated Ethernet frames are then mapped into a configurable number of VCAT low-order and high-order payloads, such as VC12 synchronous payload envelope (SPE), VC3 SPE, or a contiguous concatenated (CCAT) payload such as VC4 SPE. Up to 63 VC12 SPEs or three VC3 SPEs can be virtually concatenated.
