SCP6G01-GL-BWH 56T190600006 NEC 5000S

Features:

Total Design concept

• The NEC family of SDH system equipment features a highly compatible, unified design platform. 5000S microwave system technology is based on the longstanding integrity of NEC expertise. With its advanced integrated design, the 5000S accommodates higher rack density than other systems of its kind. The equipment comprises two main shelves on a single European Telecommunications Institute (ETSI) rack. Branching (BR) and Transmitter/Receiver Equipment (TRP) sections are built on the upper shelf, with Modulator/Demodulator Equipment (MDP) and Multiplexer (MUX) sections on the lower shelf.
