E1 Ethernet V.35 STM-1 SDH equipment:H9MO-LMA

The MetroEdge-Express is built on SDH/MSPP technology. It is aimed at providing both TDM based traditional telecom services and ever

growing Ethernet based data services. There are two types of equipment in the MetroEdge-Express family, the CPE end equipment


1.TM, Multi-Service, including E1, FE, V.35
2.Flexible options for the STM-1 fiber optic interface, including single fiber duplex, as well as different power and wavelength choices.
3.Standard based GFP/VC-12 VCAT, support VLAN, EoS
4.Built-in BERT and loop-back capabilities
5.Framed and unframed V.35
6.Remote AC power failure alarm
7.Standard 19 inch 1RU box, compact, lightweight, low power consumption
8.Dual mode power supply, -48V DC or 100~240V AC field selectable
9.Support online upgrade of embedded program and FPGA program
