Product function: transmission of 4 E1/8E1/16E1 signal through fiber

Product Characteristic

• Provides 4 E1/8E1/16E1 The G.703 connection(namely provides 120/240/480 roadbeds groups telephone channel)
  
• Realizes long-distance monitoring of this end equipment to the far-end equipment (two-row indicating lamp, upper row indicates local status, lower row indicates far-end status )
• Provides function of ordering 4 E1/8E1/16E1 to loop return from the remote end, fiber self-loop at local end; and provides a group service telephone interface (optical)
• Three power suppliers:DC-48V,DC+24V or AC220V (optical)
  
• Transmitting range:2-120Km
• Three double fiber bidirectional and the single fiber bidirectional type may select
• Conforms to the telecommunication level operation requirement, and does not have the fault time equally (MTBF) above 70000 hours
• Has the redundant reliability, provides installment of 19”rack, desktop sets, the wall hanging, and card-inserting, at the same time 19” rack has the alternating and direct power supply.
