Multiservice Access Multiplexer (2U)



E1 Time Division Multiplexer for fractional E1 network across, which is designed for nonstop operation.

  • 6 slots available for hot-swappable I/O cards and two slots are provided for power supplies
  • Optionally accommodates up to two separate power supplies, which may derive power from AC (110/220) or DC (-36~72V) power sources
  • Provides E1 copper uplink, the maximum E1 supports up to 96 E1 channels with cross connection for Voice and Data, the interface included RS232, V35, FXS, FXO, ET100 & E&M.
  • Provides and maintains our own SmartView EMS (Element Management System) which is a Java based client/server manager for monitoring, configuration, maintenance, or troubleshooting a large number of network elements over a long period of time.
  • Supports MAX. 96xE1 with full cross-connect, Supports DS0 cross-connect
  • Supports 16 channel Main E1 LTU card
  • Supports E1 time slot broadcast function
  • Modular design for Voice I/O card, the voice I/O card has two sub-module, each sub-module supports 4-port FXO/FXS
  • All modules and cards support hot-swapping
  • DCE card types included N*64K, RS232(Sync/Async) ET100, ET100R, E&M, FXO, FXS...etc.
  • Supports Console, Telnet, SNMP and GUI management
  • Available types of power built-in : AC+AC, AC+DC, DC+DC
