E1 (2.048 Mb/s) / T1 (1.544 Mb/s) J2294D
General
This interface is a plug-in module suitable for plugging into the J2300C/D/E
Agilent 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- 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 T1 information, see J2298D specifications.
