1.5 Features
The MultiDSU56K provides many useful features. Standard features include V.35 and RS232
connections and either synchronous or asynchronous transmission; synchronous at rates up to
56000 bps and asynchronous up to 19200 bps; selectable digital rates that match the services
offered by the carriers. Other features include user-selectable clocking options, elastic store for
analog off-net extensions, anti-streaming, and RTS and DSR signal forced on selection.
Your MultiDSU56K provides the following features:
• supports direct connection to the DATAPHONE Digital Data Service (DDS) or compatible
network
• selectable sync speeds of 2400, 4800, 9600, 19200 and 56000 bps
• selectable async speeds of 2400, 4800, 9600, and 19200 bps
• point-to-point and multipoint operation
• Standard RS232C, V.35 and DDS interfaces provided
• anti-streaming (for multi-point operations)
• elastic store (for analog off-net extensions)
• system status
• circuit assurance
• multiple selectable clocking
* External clocking
* Internal clocking
* DDS (slave) clocking
• RTS signal forced on selection
• DSR signal forced on selection
• multiple MultiDSU56K-activated diagnostic tests:
* Local loopback test
* Digital loopback test
* Test pattern generator/detector
• multiple Telco-activated diagnostic tests:
* DSU loopback test
* CSU loopback test
