1.5 Features
The MT56DSU-R provides many useful features. Standard features
include V.35 and RS232 connections and either synchronous and
asynchronous transmission;
and asynchronous up to 19200 bps; selectable digital data 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 Multi-Tech DSU/CSU provides the following features:
•
supports direct connection to the DATAPHONE
Service (DDS) or compatible network
•
selectable sync speeds of 2400, 4800, 9600, 19200 and 56000
