Atec Adtech-SX-12 Series - Manual (Page 2)

Hardware Description
Each SX/12 simulator is housed in a rack mountable chassis and uses interchangeable plug-in modules to support various data channel
(physical) interfaces. The front panel includes an LCD display and keypads for user input and control. All front panel functions can also be
accessed remotely via an optional IEEE-488 or RS-232 remote control port. Other hardware options providing additional delay and error
simulation capabilities are also available.
Features and Specifications
There are three different versions of the SX/12. All function identically except for the maximum link speed each version supports. An
Extended T1/E1 Simulation option is available for the SX/12-1 and SX/12-2 versions. This factory installed hardware option provides
additional delay and error simulation parameters for T1 (1.544 Mb/s) and E1 (G.703 2.048 Mbps) data streams.
