General
This interface is a plug-in module suitable for plugging into the J2300C/D
Advisor mainframe and the J2900A High Speed undercradle. The J2294D has
DB-9 and RJ-45 connectors which, with converter cables, can connect to 120
Ohm Small Siemens connectors. 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.
This module can be configured as a T1 (1.544 Mb/s) or as an E1 (2.048 Mb/s)
interface. For T1 information, see J2298D specifications.
