Cisco 15454-CE-MR-10 CE-Series Ethernet Card
Through its portfolio of Ethernet service cards, the Cisco 15454-CE-MR-10 has enabled service providers and enterprises to effectively and efficiently expand their network capability from transporting only time-division multiplexing (TDM) services to delivering multiple services over a single, converged architecture and eliminating the need for multiple overlay infrastructures.
The CE-1000-4 card carries any Layer 3 protocol that can be encapsulated and transported over Ethernet, such as IP or IPX. The Ethernet frame from the data network is transmitted into the gigabit interface converter (GBIC) on a CE-1000-4 card. The CE-1000-4 card transparently maps Ethernet frames into the SONET/SDH payload using packet-over-SONET/SDH (POS) encapsulation. The POS circuit with encapsulated Ethernet is then multiplexed onto an optical card like any other SONET synchronous transport signal (STS) or SDH synchronous transport mode (STM). When the payload reaches the destination node, the process is reversed and the data is transmitted from the GBIC in the destination CE-1000-4 card onto the Ethernet of the data network. The CE-1000-4 card has four front-end Ethernet ports which use standard GBIC connectors for Gigabit Ethernet. Ethernet Ports 1 through 4 each map to a POS port with a corresponding number. These Ethernet ports can be daisy chained. The CE-1000-4 supports IEEE 802.3x flow control and allows you to enable symmetric flow control, enable asymmetric flow control, or to disable flow control. The configuration is done in CTC at the port level.
