flexible compact equipment for E1 streams transmission through packet networks via TDM over packet (TDMoP), Structure-Agnostic Time Division Multiplexing over Packet (SAToP), Structure-Aware Time
Division Multiplexed Circuit Emulation Service over Packet Switched Network (CESoPSN) technologies. The devices provide transparent independent connection of classic telephony equipment upon a unified network infrastructure. Optic-fiber interfaces which are realized through connected SFP and CSFP modules and embedded Ethernet switch allows to construct networks with different topologies without additional equipment.
