4E1 PDH Multiplexer
Product Description
Product Specification/Models E1 Port Ethernet Port Power Supply Operating Environment
4E1 PDH Multiplexer can multiplex 4E1 and 2-ports Ethernet (10/100Mbps line speed) signals in one fiber channel to transmit. It is suitable for low capacity, point-to-point application of remote transmission. The circuit part of the equipment is fully digitized. The whole equipment is reliable, stable, easy to install and maintain. It has good temperature and voltage characteristics, complete alarm functions, one RS232 asynchronous interface and remote loop back functions(from software). At the same time, it can be managed from management software.
Functional Characteristics:
–Providing up to 4 E1 channels and 2 optional 10/100Mbps Ethernet channel
–Fiber port bit rate: 150Mbps, up to 120Km distance without repeater
–E1 Line code: HDB3, compliant to G.703, G.823 and G.742.
–E1 channel support both 75ohm & 120ohm impedance
–Ethernet port support 10/100Mbps auto-detection, Full/Half Duplex auto-negotiation
–Ethernet port can transimit VLAN tag
–Complete alarm functions
–Providing an RS232 asynchronous interface
–Supporting the local/remote E1 loop back
–Remote loop back provided by software and hardware
–Providing RS232 port for management, GUI interface
–Standalone,220VAC or -48VDC power supply optional
