Overview Plug-in Modules Specifications Product Photography

The SLICE is a small, self-contained switching system, designed to serve as an integrated communications platform, providing a  flexible, portable and reliable Class 4/5 switch in a single, 1U platform. This compact switching system has the power, capability, and simplicity of REDCOM’s High Density Exchange (HDX) in a self-contained, rack-mountable package. Weighing less than 15 pounds, the SLICE is a REDCOM switch in a 1U (1.75 in./4.45 cm) platform that is easy to install in standard 19 inch (48 cm) equipment racks, and is ideal for small stand-alone or remote applications.

With the SLICE, you can service a full spectrum of switching system sizes. A single 1U unit provides 24 analog line circuits, 4 BRI-S line circuits, 2 digital spans (E1/T1), and integrated modular jacks (RJ-11, RJ-45). The SLICE is a completely integrated switching system that can be configured as a public end/tandem office or as a private network node element.

The SLICE has extensive capabilities for both public and private network settings including specialized tandem features ideal for Power Line Carrier applications. The SLICE  provides both domestic and typical international gateway functions, including the capability to perform interface and protocol conversion between U.S. and international standards. Two rear-accessible positions for interface modules on the SLICE, allow either position to be equipped with one of three hot-swappable modules.

Multi-use, wide adoption

The SLICE has been widely adopted by the central office market, private network developers, government and defense users, and emergency response agencies worldwide. Due to its compact size and low power consumption, the SLICE is particularly suited to distributed networks such as those employed by oil platforms, rail and utility networks, and shipboard communications.  The SLICE has a full suite of business features including ISDN and extensive conferencing in order to meet the needs of the most demanding users. Multiple sites may be seamlessly interconnected with REDCOM’s advanced ClusterNet™ technology, which connects multiple SLICE units allowing them to function as one integrated system.

Revenue generation

As a fully functional public exchange, the SLICE provides modern services and revenue-generating features in a small footprint. Replacing existing multiplexers with the SLICE yields enhanced services to subscribers, while retaining the ability to allocate limited bandwidth. SLICE switches can also be connected together for greater capacity. For instance, a 48-subscriber exchange comprised of two integrated SLICE switches can measure as little as 3.4 inches (8.8 cm) high. In addition, when used in conjunction with the REDCOM HDX, the SLICE provides a powerful host/remote combination.

Low maintenance

The SLICE user interface is identical to other REDCOM products, such as the HDX, thereby reducing training costs for existing customers. Installation and updates are simple and spares inventory is minimal, as is routine maintenance. Because of its unique design, the SLICE allows for easy firmware upgrades and remote database administration. Line and cooling modules are field-replaceable making installation and service a snap.

Host/Remote

In conjunction with the REDCOM HDX, the SLICE® provides a powerful Host/Remote combination. A single HDX shelf can coordinate multiple remote SLICE®s operating in low density locations.

Interchangeable plug-in modules for REDCOM SLICE

The SLICE has two rear-accessible positions for interface modules. Either position can be equipped with your choice of interface modules. These modules can be replaced in the field with power applied.
