General
This interface comprises a plug-in module (J3759B) suitable for plugging into
the J2300C/D Advisor mainframe and the J2900A High Speed undercradle. The
J3759B supports both ATM and frame-based technologies such as Frame Relay
(CIR & SLA), HDLC, PPP. This module can also be configured for use as a DS3
(44.736 Mb/s) interface; see below for details.
