Pseudowires for backhaul
We have noticed a steadily growing trend of industry pundits claiming pseudowire technology is fast becoming one of the preferred methods for cellular backhaul. With higher-speed data networks comes a greater need for bandwidth, and, in turn, the traditional infrastructure equipment: the T-1 links used to connect cell sites or aggregation hubs to the terrestrial network have also gone up in price. Enter pseudowires, a broad set of standards for carrying a range of protocols including T-1, over IP, Ethernet or other packet networks that enable carriers to connect their TDM-based equipment to a more efficient Ethernet access network.
