▶ Fox-155
 
 
 
   
 
By connecting DS-0 class, DS-1, DS-1E and DS-3 as tributary signal, FOX-155E multiplexes them into STM-1(155.520Mbps) class digital hierarchy and transmits optically to the counterpart equipment. With the opposite processing in the same way as well, it can provide various services such as conventional voice-class line, digital data line up to 64Kbps, public telephone, ISDN, N × 64Kbps, DS-1, DS-1E, DS3 signal, and ADSL, etc. It interworks with the switch using V5.2 interface and is composed of optical Tx/Rx providing IDLC function and synchronous digital multiplexer to enable various network topologies such as star, linear and ring.
