General
This interface module suitable for plugging into the J2300C/D Advisor main-
frame and the J2900A High Speed undercradle. This module has 4 bantam
connectors and two 8-pin connectors that can easily switched between RJ-48C
and RJ-45 pin wiring. The J2298D module handles frame-based technologies
such as Frame Relay (CIR &SLA), 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 E1 information, see J2294D specifications.
