The HiGain
®
Multiplexer Unit, HXU-358 V1.04, is the multiplexing
component of the Soneplex
®
Wideband 3190 system. It can also be installed
in the HiGain Access Concentrator Express (ACE) chassis, a single-rack
enclosure (see
“Appendix B - HXU-358 Installation for ACE Chassis” on
for more information). The HXU-358 multiplexes 28 DS1 lines into
a single Digital Signal, level 3 (DS3) interface at a signal rate of
44.736 Mbps.
The Wideband 3190 typically incorporates two HXU-358s, one board
functioning as the active board, the other as a standby. This redundancy
provides backup protection. In the event of a failure, the active relinquishes
control to the standby HXU-358 within 50 ms.
