DDS 4-wire J2908A
General
This interface comprises a plug-in module (J2908A) suitable for plugging into
the J2300C/D/E Agilent Advisor mainframe or J2900A High Speed undercradle.
This WAN module can be used with T1 Digital Data Systems (DDS) circuits to
monitor and decode the data traffic of individual DDS subrate users. The
module is only available in the United States of America
