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 an E3

(34.368 Mb/s) interface; see above for details.
