STM1 / 4 Ausstattung

STM1/4 Equipment has a popular 19-inch box structure which is com- posed by a main board and 4 selectable slots. The system em- ploys a good many advanced techniques including LSI, PLD, surface paste and multiplayer printing for plate. And a small size and consummate functions are provided. It can be config- ured as a network element such as ADM, MADM, TM, and REG.. 16/48/1008VC4/VC3/VC12cross-connection and supports unidireconal, bi-directional and broadcasting Multiple topologies including P to P, line, ring, star and multi-rings 10/100M Ethernet interface of GFP/LAPS encapsulation and VC Virtual Concatenation technique High/low speed Vx data interfaces Crossing ability between the high order (16×16VC4) and low order (1008×1008VC12) provided Various interfaces offered, including E1, E3, E4, 10/100Base-T, V.35/V.11/V.24, STM-1e/ o, etc.. Exterior clock, the SDH circuitry clock, the 2Mb/s tributary clock and the interior clock supported MSTP with low power consumption of about 30W Smooth and easy upgrade from STM1 to STM4 through replacing modules Multiple network protections supported
