Cleveland, Ohio Embedded Planet has introduced the EP50120M Circuit Emulation Service over Packet (CESoP) module for telecommunications providers transitioning between legacy circuit switched networks and newer IP-based networks. The CESoP module provides a cost-effective method to bridge the two types of networks and safely migrate from legacy to next-generation networks.
The CESoP module offers the traditional circuit emulation service over a packet network and is used for TDM trunking over a range of transport protocols including Internet Protocol (IP), MPLS and Ethernet. CESoP is widely used in the access market for a wide range of applications including cell-site backhaul, Metro Ethernet equipment, DLCs, MTU/MDU equipment, data communications equipment, and EPON technology.
The EP50120M uses a Freescale MPC8248 as the control processor and the Zarlink ZL50120 for CESoP processing. The ZL50120 is capable of supporting both structured and unstructured TDM data. It includes a 10/100 customer side Ethernet port that can be used to aggregate data traffic with voice traffic and then back hauled using the 10/100/1000 provider side port.
The EP50120M board is designed to operate as a stand-alone module for software development and prototype development. The board comes complete with a U-Boot bootloader and VxWorks Board Support Package to speed application development. The board is available in prototype or production quantities and a reference design package can be purchased for rapid deployment of custom products.
