The WBS-3190 multiplexes 28 HDSL lines into a single DS3 or STS-1 line interface. By providing industry-
standard interfaces between system components that are independently configured, it maintains a truly
open architecture. This architecture allows any industry-standard 3190 card to access the Wideband
shelf. Despite its small form factor, the WBS-3190 provides a common architecture that supports all
system functions. It houses up to 28 line units (HLU), a management unit (HMU), two multiplexer units
(HXU) and an optional fan assembly (HFA). The HXU multiplexer system provides a managed, high-level
DS3 or STS-1 trunk interface at the CO. Both TL1 and TAO (craft-VT100) management systems are
supported on X.25, 10BASE-T and RS-232 interfaces along with alarm relay contacts and redundant
A/B office battery connections. A 7-foot CO rack can support up to six WBS-3190 chassis and meets all
NEBS requirements while providing up to 168 DS1 access lines to the field.
Open System Advantages
The HiGain Wideband 3190 delivers critical advantages through an open-system architecture. This
design approach, along with complete backward compatibility with existing HiGain components,
results in an extremely low cost per port. Additionally, reliability is greatly enhanced, and long-term
operating costs are contained through “single-wire” management capabilities that enable precise,
flexible system monitoring.
