T1 (1.544 Mb/s) / E1 (2.048 Mb/s) J2298D

General

This interface module suitable for plugging into the J2300C/D/E Agilent Advisor

mainframe and the J2900A High Speed undercradle. This module has 4 bantam

connectors and two 8-pin connectors that can easily switch between RJ-48C

and RJ-45 pin wiring. The J2298D module handles frame- and cell- based

technologies such as ATM, Frame Relay, HDLC, SDLC, X.25, ATM DXI and PPP

in addition to BERT.

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.
