Insterface Standards:
V3.5 is a specification for a connector type, pin allocation and signal level used for synchronous communications interfaces in many parts of the world. The original standard was for a now defunct modem.
The signal electrical characteristics used in V3.5 interfaces are combination of V.11 (for clocks and data) and V.28 (control signals).
Interface Characteristics:
V3.5 uses differential interfaces for the clock and data signals which are the only signals requiring high switching speeds for high-speed communications. Throughput of up to 10Mbps is typical, dependent on the equipment and cable used.
The other signals are unbalanced (single wire) and normally incur a minimum of state changes. Separate clock lines are used for receiving and transmitting data.
Interface Connector Types and Pinouts:
V3.5 interfaces are common in some parts of the world primarily due to its adoption by telphone companies and their equipnent suppliers. Commonly used bit-rates are 64kbps, 128kbps, 256kbps etc. The X.21/V.11 interfaces used for the data and clock signals enable high throughput but maximum distances are not as high as for X2.1/v.11 due to the use of single-ended V2.8 interface for the control signals. Typical protocols used over V3.5 interfaces are HDLC, X2.5, SNA and PPP.
