   Features

　

 11U-height compact-size designation.
 Provides 256×256 VC4 level non-blocking cross connection, or 2016×2016 VC12 level supporting unidirectional, bi-directional and broadcasting.
 Provides sub-network connection protection and 1+1 multiplex section protection, supporting traffic communication between them.
 Applicable for a number of network configuratins: point to point, linear, ring, star, tree, multi-ring, ring crossing, ect.
 Provides E12(2M), FE(10M/100M Ethernet) tracffic interface, and STM-1/4/16 interfaces.
 Provides three levels of VC4, VC3 and VC12 cross connect for FE board, supporting both LAPS and GFP EOS encapsulation and LCAS standard.
 Provides virtual concatenation function for FE, and the maximum virtual concatenation quantity for VC3 level is 3 and for VC12 is 63.
 Capacity for interfaces:
· E12 interface: up to 128 channels 
· FE Ethernet interface: up to 16 channels
·STM-16 optical interface: up to 6 channels
·STM-4 optical interface: up to 13 channels
·STM-1 optical/electrical interface: up to 26 channels
 Either way for the use of traffic: independent or protecting each other among optical interfaces.
 Configurations of complicated SNCP network, such as 2.5G-622M Multi-Ring, 622M-155M Multi-Ring, 155M-155M Multi-Ring, etc.
 Allows configuring STM-1 system to/from STM-4 or STM-16 system only by replacing interface modules; simply upgrading.
 Provides orderwire interface (2-wire interface), with the functions of all-call, group calling and selected calling.
 One 64kbit/s V.11 or V.24 user data interface per optical interface.
 Provides timing synchronous interface:
 2048kbit/s or 2048 kHz external clock
 2048kbit/s tributary
· STM-1, STM-4 and STM-16 timing source inputs
 2048kbit/s or 2048 kHz external timing source output
· SSM function
 Provides DCC channel of D1 to D3; Using TCP/IP communication protocol.
 Provides F (10Base-T) and f (RS232) network management interfaces for configuration, alarm, performance, maintenance and security functions of ITU-T definition.
 Provides ports for eight Housekeeping Alarms, four Housekeeping Controls, and a set of Alarm Output interface.
 Provides local/remote firmware download: in-service upgrading is available for easy maintenance.
 Allows upgrading hardware configuration data without replacing equipment.
 Provides the network management for remote connection via serial interface or LAN, which allows monitoring remote NE.
 Supports the following application of fiber transmission:
·Super Long-Distance (≤80km)
·Long-Distance (≤40km)
·Short Distance (≤15km)
 Provides fans to disperse heat forcibly, or allows natural heat dispersion without using fans as well; provides the fans controlling temperature and inspecting their own status to guarantee the equipment running stably.
 Flexible structure designing: allows the front access or the rear access by the method of mounting shelves.
