ZXDSL 9210 (V3.1) Broadband Universal Access Equipment Technical Manual
4-18
3. The Ethernet processor implements switching between ports within boards and
provides the G.Link bus responsible for switching and convergence between
SCBF and other boards in the system.
4. The Ethernet module implements Ethernet user access.
The Ethernet uplink subcard and Ethernet interface base plate implement G.Link bus
switching between subcard and backplane by means of a switching chip.
4.2.6.3 EICM Interfaces
EICM provides four 10/100M Ethernet electrical interfaces and four 100M
single-mode optical interfaces in compliance with IEEE 802.3u via FEC subcard.
EICM provides four 10/100M Ethernet electrical interfaces and four 100M
single-mode optical interfaces in compliance with IEEE 802.3u via FNC subcard.
4.2.7 EICG
4.2.7.1 Functions of EICG
EICG provides three channels of 1000M Ethernet optical interfaces in compliance with
IEEE 802.3z. EICG implements the following functions:
1. Provides integrated switching between three 10/100/1000Mbps Ethernet optical
interfaces and G.Link bus interfaces.
2. Distributed L2 switching engine at a line speed.
3. Provides flexible CoS mapping.
4. Provides two priority queues and supports eight CoSs.
