The Wideband 3190 (HMS-358 List 1 and List 2) combines an industry-standard multiplexer function with the
®
HiGain
High-bit-rate Digital Subscriber Line (HDSL) distribution system, providing the lowest-cost T1 delivery
system available. The Wideband 3190 terminates 28 to 112 ports and multiplexes them into a single, high speed
network interface with full metallic and electrical test access on all low speed ports. By selecting the multiplexer
card, a variety of network interfaces can be accommodated such as DS3, STS-1, and OC-3. In addition, functions
such as IP, Frame Relay, and data grooming can be supported through line card selection. Use of the same
multiplexing (ACE) and DSL (HiGain) units found in ADC standalone products assure a versatile and
cost-effective solution to your system requirements. This open architecture allows any industry-compliant 3192
line card to function in a Wideband 3190. (ADC recommends that third-party line cards be certified for
compliance with a Wideband 3190.)
For management, both Terminal Access Option (TAO) and Transaction Language 1 (TL1) systems are supported
on X.25, 10BASE-T, 10BASE-2, and RS-232 interfaces. The Wideband 3190 also features standard alarm relay
contacts and accepts a redundant A/B office battery source.
The Wideband 3190 (with a full complement of remote equipment) can be configured with up to six chassis (up
to 672 lines) in a 7-foot rack and meets NEBS requirements for CO equipment.
The Wideband 3190 is part of a protection switching application solution. Protection switching application
solutions have the following system requirements: two HXU-358 Multiplexers (software version 1.04 or higher),
an HMU-319 List 7A or List 7C Management Unit (software version 3.06 or higher), an HLU-316 List 6 Line
Unit, and an HRE-206 Remote Enclosure equipped with a PSC-606 Protection Switching Controller. For more
information, see "Protection Switching Controller Technical Practice," PSC-606 List 1, section number
150-606-100-xx.
