▶ Fox-622
FOX-622V synchronous optical transmission equipment comprises 622M COT, RT and 155M POI. 622M COT and RT equipments receive tributary signal as DS1E, E2, DS3 and STM-1 from central office and base station to multiplex STM-4 synchronous digital signal and transmit it to the counterpart equipment. By performing opposite processing in the same way as well, PTP and ring topology can be implemented.
• Provides for a variety of line capacity services, Network architectures and Technologies.
- 622M COT : 4 STM-1, 12 DS3, 48 E2, 147 E1
- 622M RT : 2 STM-1, 6 DS3, 24 E2, 63 E1
- 155M : 3 DS3, 12 E2, 63 E1
• Provide versatile network configuration ( RING, PTP )
• Compact Size - 19” standard Rack type
