Shelton, Conn.TranSwitch Corp. is planning to sample EtherMap-PDH, a device that delivers Ethernet services into the last mile over existing copper infrastructure.
EtherMap-PDH, part number TXC-07861, is a protocol converter that transports Ethernet services over existing PDH (plesiochronous digital hierarchy) signal formats. Ethernet-over-PDH (EoPDH) is an extension of Ethernet-over-SONET/SDH (EoS) to bring Ethernet services closer to the subscriber.
With EtherMap-PDH, Ethernet frames can be mapped through GFP/HDLC/LAPS into bonded PDH signals. The chip is compliant with the recently ratified ITU-T G.8040 and G.7043 standards. And it can be designed into any platform that has a PDH interface for wire line and wireless applications.
Its three modes of operation include Ethernet frames mapped into 16 x E1/T1/J1; Ethernet frames mapped into 3 x DS3; and Ethernet frames and existing legacy services multiplexed into a channel-based DS3, with 1+1 protection.
"The EtherMap-PDH device will accelerate the implementation of packet-based networks while ensuring a robust encapsulation scheme with GFP and flexible bonding requirements with VCAT," said Johnny Leung, director of product line management for TranSwitch, in a statement.
Samples will be available in January 2006. Depending on the volume, the device will cost between $50 and $100, according to a spokesperson.
