The configuration of SDH equipment is basically the same. This book uses the 1660SM model of ALCATE as an example for description. 1660SM equipment subrack front panel structure diagram. The size of the subrack is 482 (width) × 250 (depth) × 650 (height) mm.
- SDH device panel
Take 1660SM 2.5G as an example, its matrix cross capacity is 96×96 VC4 or 4032×4032 VC12. The maximum interface is 4×STM-16; the maximum is 16×STM-4; the maximum is 64×STM-1 or 140Mbit/s; the maximum is 48×34/45Mbit/s; the maximum is 378×2Mbit/s; the maximum is 400×l0/100Mbit/ s Eth/FE interface; maximum l28 GE interfaces; equipment protection (1+1, l:N). Network protection STM-N port provides 2-wire multiplex section protection ring (2F MS-SPRing), multiplex section protects MSP, and provides channel protection with and without monitoring signals on all VC levels (SNCP/I and SNCP/N) ), provides IP Ethermet (Ethernet) business capabilities, and provides AU4-4c & AU4-16c cascading.
