E-Series Modes

E-Series Multicard EtherSwitch Group

Multicard EtherSwitch group provisions two or more Ethernet cards to act as a single Layer 2 switch.

to STS-6c of bandwidth between two Ethernet circuit points for the ONS 15454 or ONS 15454 SDH
E-Series cards, but allows you to add nodes and cards and make a shared packet ring.

Caution If you terminate two STS-3c/VC4-2c multicard EtherSwitch circuits on an Ethernet card and later delete
the first circuit, also delete the remaining STS-3c/VC4-2c circuit before you provision an STS-1/VC4
circuit to the card. If you attempt to create an STS-1/VC4 circuit after only deleting the first
STS-3c/VC4-2c circuit, the STS-1/VC4 circuit will not work and no alarms will indicate this condition.
To avoid this situation, delete the second STS-3c/VC4-2c before creating an STS-1/VC4 circuit.

E-Series Single-Card EtherSwitch

On all E-Series cards, Single-card EtherSwitch allows each Ethernet card to remain a single switching
entity within the ONS node.
