EtherMap®-PDH TE8

Highly Integrated Ethernet to PDH Mapper for Wireless and Wireline Applications (TXC-07869)


The demand for Ethernet services has forced Service Providers to reconsider their deployment strategies of next-generation wireline and wireless platforms. As a result, how can Service Providers offer Ethernet services with minimal impact on capital and operational expenditure.

The EtherMap®-PDH TE8 device provides a solution that is cost-effective by re-using both the existing copper infrastructure and the typical SONET/SDH platform at the central office. An EtherMap-PDH enabled line card on a CPE maps Ethernet frames via GFP/HDLC/LAPS into bonded PDH signals. The ability to extend the Ethernet service to the last-mile will provide a complementary solution to Ethernet-over-SONET/SDH (EoS).

The EtherMap®-PDH TE8 device maps Ethernet frames into 8 x E1/T1/J1 PDH signals.

The EtherMap®-PDH TE8 device is compliant with the recently ratified ITU-T G.8040 and G.7043 standards. Feature-rich functions such as VLAN separation, Q-in-Q, granular VCGs and over-subscription allow a complete System-on-a-Chip (SoC) solution. The EtherMap®-PDH TE8 device can be designed into any platform with PDH interfaces.
