The system supports low speed synchronous / asynchronous V.24 interface and high speed synchronous V.35, G.703 data interfaces. The equipment also supports FXO, FXS and inter-exchange E&M interface used for inter-connecting telephone exchanges ("junction mux application").
The available data interface options include:
- G.703, co-directional, synchronous data interface @ 64Kbps.
- V.35, synchronous data interface @ 64Kbps.
- "N" x 64Kbps, V.35, user configurable, synchronous data interface. The value of "N" may by configured by the user according to bandwidth requirements. The maximum value of "N" = 16 (1.024Mbits/Sec.)
- V.24 / RS232, asynchronous data interface for low-speed data applications ranging from 300Bps to 19.2Kbps.
- iDSL (ISDN DSL) leased line interface
- 10BaseT Ethernet G.703, co-directional, synchronous data interface @ 64Kbps 61
- The VCL-30 offers an excellent flexibility on the choice of transmission medium over which it may be deployed. The transmission medium may be either twisted copper cable pairs, optical fiber cable, or wireless.
