The HiGain
®
Multiplexer Unit, HXU-359 List 1, is the SONET multiplexing
component of the Soneplex Wideband 3190. It can also be installed in the
HiGain Access Concentrator Express (ACE) chassis, a single-rack enclosure.
The HXU-359 multiplexes 28 DS1 lines into a single Synchronous Transport
Signal (STS-1) interface at a signal rate of 51.84 Mbps.
The Soneplex Wideband 3190 typically incorporates two HXU-359s, one
board functioning as the active board, the other as a standby. This redundancy
provides Automatic Protection Switching (APS). In the event of a failure, the
active HXU-359 relinquishes control to the standby HXU-359 within 50 ms.
Future enhancements to this product will support an optional Optical Carrier
(OC-3) interface and E1 interfaces.
