E-Series Provisioning of Ethernet over SONET

The E-Series cards incorporate Layer 2 switching within the card. The ONS 15454 E-Series cards include the E100T-12/E100T-G and E1000-2/E1000-2-G cards. E-Series cards support VLAN, IEEE 802.1Q, spanning tree, and IEEE 802.1D. An ONS 15454 holds a maximum of 10 Ethernet cards, and you can insert Ethernet cards in any multipurpose slot. The E100T-12/E100T-G cards provide 12 switched, IEEE 802.3-compliant 10/100 BASE-T Ethernet ports. The ports detect the speed of an attached device via autonegotiation and automatically connect at the appropriate speed and duplex mode, either half or full duplex, and determine whether to enable or disable flow control. The E100T-G is the functional equivalent of the ...
