II. Product Features
Ø Adopts 19-inch standard 3U chassis with plug-in card design; provides 17 slots for 3U user cards;
Ø Two SFP-type STM-4/1 optical interfaces, supporting SDH ring and chain topologies, with 1+1 tributary channel protection;
Ø Provides 252×252 VC-12 level non-blocking cross-connection between TDM interface services, supporting unidirectional, bidirectional, and broadcast services;
Ø Provides up to 24 E1 channels with non-blocking 64K timeslot cross-connection;
Ø Supports access of up to 180 channels of 64K timeslot services;
Ø Provides 4 groups of physically isolated EoS Ethernet, each with configurable bandwidth of N×VC12 (N=1~50); each group also provides 1 reserved extended Ethernet port; works with the 8FE card to expand the number of extended Ethernet interfaces;
Ø Provides a 5-in-1 2-wire audio card: 3U-8MVOICE; each card provides 8 channels of 2-wire audio; each 2-wire audio channel can be configured as FXO/FXS/hotline/magneto/2100Hz magneto mode;
Ø Supports insertion of radar data access card, providing 4 channels of radar data service interfaces per card, supporting synchronous and asynchronous operating modes; in synchronous mode, transmission rates support 300bps/600bps/1.2kbps/2.4kbps/4.8kbps/9.6kbps/19.2kbps/38.4kbps/57.6kbps/64kbps/115.2kbps/128kbps; in asynchronous mode, the maximum transmission rate is 38.4kbps, with automatic adaptation for rates below 38.4kbps;
Ø Clock source can be selected from line clock, external clock (2Mbit/s or 2MHz), and free-running oscillation;
Ø Provides 17 user slots, compatible with multiple service cards, supporting access of voice and data services including PDH, E1, FXO/FXS, V.24/V.28/V.35, EM2/4, hotline telephone, magneto telephone, high-fidelity audio, X.50, and 10M/100M Ethernet;
Ø Supports insertion of 3UMPCONV user optical port expansion card and WG300 signaling switching card;
Ø Standard model provides a repeaterless transmission distance of 40 kilometers; custom configurations are available for distances exceeding this range;
Ø Provides Ethernet management channels based on DCC, E1, N*64K, and TCP/IP, with SNMP simple network management protocol support;
Ø DC -48V and AC 220V power supply, with optional DC+DC, AC+AC, AC+DC dual backup power configurations;
