II. Product Features
The chassis adopts a 19-inch standard 6U rack-mount, plug-in card design; provides 10 6U user card slots;
The IDM MUX300 optical-electrical integrated device integrates SDH transmission and PCM service access technologies;
Provides 252×252 VC-12 level non-blocking cross-connect, supporting unidirectional, bidirectional, and broadcast services;
Supports 2 SFP interface STM-1 optical access ports, enabling ring, chain, star, and other network topologies;
Provides 4 groups of physically isolated EoS Ethernet channels, each with configurable bandwidth of N×VC12 (N=1~50); each group also reserves 1 extended Ethernet port; pairs with the 8FE card to expand the number of Ethernet interfaces;
Supports Synchronous Equipment Timing Source (SETS), with optional tracking of optical line timing source or external synchronization input/output (2.048Mbit/s or 2.048MHz), and automatic timing source switching based on fault conditions or SSM; clock sources can be selected from line clock, external clock, or free-running oscillation;
The standard model provides a non-repeatered transmission distance of 40 kilometers; custom configurations are available for distances exceeding this range;
Provides an F (10M/100M) network management interface, offering the five major functions recommended by ITU-T through the Netguard management system: configuration, alarm, performance, maintenance, and security; also provides a device network management cascade interface;
Supports SNMP simple network management protocol;
DC -48V and AC 220V power supply, with optional DC+DC, AC+AC, AC+DC dual backup power configurations;
