General
This interface is a plug-in module suitable for plugging into the J2300C/D
Advisor mainframe and the J2900A High Speed undercradle. The J2296D has 75
Ohm BNC connectors which. This module handles frame-based technologies
such as Frame Relay, HDLC, SDLC, X.25, ATM DXI, and PPP. ATM and BERT are
expected for future releases.
