PTN 1900s are multi-service frame-shaped devices for packet transport and are mainly used for integrated access on a packet transport network. They support 10GE macro base station service aggregation, easily adapt to the ambient environment, provide various network- and device-level protection mechanisms, and ensure highly reliable service aggregation and forwarding, supporting multi-service transmission and management.
Huawei PTN series multi-service packet transport devices have been put into commercial use on a large scale, serving more than 90 carriers worldwide. The devices reduce carriers' network construction TCO and bandwidth costs and improve service deployment and network O&M efficiency.
