Multi-Service PDH Multiplexer with 16 E1 and 4 FE Ports – GAOTek

Description

Overview

GAOTek multi-service PDH multiplexer is modular structure point-to-point optical transmission equipment with LCD display, uses the FPGA chips and is easy to upgrade. The Main board provides 4 x 100 M channel Ethernet data and 2 AUX ports which are for transmitting other data such as RS232, RS485, RS422, two optical interfaces for optional 1 + 1 auto protection switch (APS). 4 slots of tributary with variant plug-in modules which included 4 x E1 channels module, 4, 8, 16 x FXO and FXS modules and 2x Nx64K V.35 module. The maximum capacity will be up to 4 plug-in modules which could be in combination with the above modules. The high flexibility, performance, is the best solution for voice, data, video services in existed market.
