Broadband connectivity to Internet has quickly become one of the most successful telecom service offerings ever. The meeting and marketplace of the future requires Full-Service Broadband. Full Service Broadband encompasses a unique combination of products and experience that will enable operators and network providers to meet this emerging demand for anywhere access to broadband services, quickly, cost-effectively and with minimal risk. Firstly, the standard of PTN (Packet Transmission Network) are analyzed. Then ,by deep analysis the key technology of PTN on MAN. The key technologies of PTN on MAN can be divided into two group: PBT, PBBREP, RRPP, ERP technology, and Carrier Ethernet with MPLS technology. At the same time, communication each other of MSTP and PTN,T-MPLS and IP/MPLS ,PBT and IP/MPLS are carried out by figures. At last, testing of PTN are analyzed, testing contents mainly include: TDM service function of PTN equipment, long time BER capability of STM-1service, time delay capability of PTN equipment, protection and provisioned backup path function of T-MPLS, Wrapping protection a function of T-MPLS loop network,and OAM functions.
