Rural telecom service providers want to grow revenue and reduce operational costs by investing in Next Generation Network (NGN) services, while leveraging existing infrastructure. But a host of challenges in the central office make this multi-technology environment difficult to transform today’s legacy infrastructure to one optimized for delivering NGN services. Service providers who want to deliver NGN services need a next-generation Carrier-Grade softswitch that leverages and preserves all the functionality and investment in legacy assets, while offering safe passage to leap-forward VoIP technology.

All-in-One VoIP & TDM platform

REDCOM’s HDX Carrier-Class 4/5 softswitch with TRANSip® offers fully integrated VoIP and TDM in an all-inclusive central office platform. In the transition to VoIP, the idea of wholesale replacement of network assets is not only expensive, it is often completely unrealistic. The HDX brings VoIP connectivity to rural central offices, providing an integrated VoIP and TDM migration platform so that you don’t require additional external boxes. You’ll avoid forklift replacements of your existing systems and gain a solution that works seamlessly with your current infrastructure

Preserve your infrastructure assets

You’ve made a significant investment in your network and the HDX helps you maximize your existing assets. The HDX maintains connectivity with voice mail, GSM, operator services, and satellite networks. Its TDM interfaces preserve your customers’ legacy equipment (including modem, fax, and Point of Sale terminals). The TRANSip architecture is based on four core elements (Call Management, Media Gateway, Media Gateway Control and Legacy Support) that allow you to transition to VoIP on your own schedule while you retain valuable network assets.

Transition to IP on your schedule

For the foreseeable future, legacy devices and networks must continue to be supported. The HDX with TRANSip offers a low risk, flexible, and cost-effective transition to VoIP. With the HDX you can start with as few as 100 IP subscribers. Operating as both a softswitch and a gateway, the HDX delivers up to 3,000 registered SIP subscribers per shelf. Its extensive TDM capabilities allow you to retain legacy equipment. The HDX is a true drop-in replacement that facilitates easy migration to VoIP at the most opportune time for your business. Next Generation Networks powered by REDCOM’s HDX enable service providers to invest in the latest VoIP technology to increase revenue while reducing costs.

HDX: a softswitch designed with the future in mind

REDCOM’s HDX is a Carrier-Class 4/5 softswitch that allows service providers to future proof their networks to interoperate today, respecting the past and anticipating the future with a wide range of protocols and interfaces, including IPv6. Offering industry-standard SIP functionality, the HDX with TRANSip is compatible with standards-based SIP phones, so you don’t have to worry about being trapped by proprietary VoIP phones or protocols. HDX supports the Simple Network Management Protocol (SNMP), monitoring network-attached devices for conditions that warrant administrative attention.

Flexibility and features help you realize cost savings

REDCOM’s HDX allows service providers to deploy flexible networks that can adapt to increasing end-user demands and competitive industry dynamics at a lower operating cost. REDCOM’s HDX is a low-cost entry-level solution that enables rural telcos to start out slow with a phased approach to IP when it makes sense for their business, and not as a wholesale replacement. HDX is an ideal “cap and grow” drop-in replacement of existing switching equipment that facilitates easy migration to VoIP at the most opportune time, while having extensive capabilities that allow rural service providers to retain legacy equipment.

Centrex provides additional revenue opportunities

The HDX allows you to compete by adding new revenue streams through Centrex services that offer VoIP telephony. The Centrex solution is deployed on your network as a price-oriented alternative to traditional phone services. You’ll gain the ability to respond effectively to marketplace demands and defend your subscriber base against low-cost competition with revenue-generating subscriber features like Centrex.

Retain customers with built-in IP compression

The HDX with TRANSip offers a full range of capabilities that allows you to address your customers’ needs while you counter low-cost competition. Flexible compression methods help you manage low-revenue subscribers by reducing bandwidth usage, while retaining high-end subscribers with high bandwidth and premium services.

Distributed & redundant architecture means enhanced survivability

The HDX system architecture minimizes the risk of single point failures as it distributes resources system-wide and network-wide, using multiple points of direct access. REDCOM HDX with TRANSip is not based on a Microsoft® Windows® operating system, and is not susceptible to any known viruses and worms used by hackers. HDX features a distributed system architecture that employs multiple call controllers which provides a strong defense against a Denial of Service (DoS) attack. HDX provides continuous service with innovative alternate routing that combines IP routes and TDM trunks.

Scalable and stackable

Based on REDCOM's patented distributed architecture, HDX is scalable and stackable with a "building block" approach. A shelf can function as a complete system by itself or be stacked to make systems up to 16,000 ports (4,000 non-blocking).

Multiple Access Solutions

HDX provides GR-303 and V5.2 (for control of RDT and access nodes) to help you concentrate network resources and reduce your outside plant. Connecting to a digital loop carrier, HDX offers connectivity to advanced technologies, remote operation capability and efficient network management. Creating multiple access solutions, HDX is a total network solution, giving you the flexibility to choose technologies that match your business needs.

REDCOM System Management

REDCOM offers a variety of products that combine to form a REDCOM Network Management System for a single point of Operation, Administration & Maintenance (OA&M) at your Network Operations Center.

• REDCOM's ClusterNet™ technology connects multiple sites and allows them to function as a truly integrated IP and TDM communications network.
• REDCOM's MAUI (Maintenance Administration and User Interface) provides a single point of OA&M. MAUI is an intuitive GUI that simplifies the configration and maintenance of your REDCOM network.
• REDCOM's Link Command System is a GUI call management system that delivers extensive conferencing, call control and handling capabilities.
• HDX includes Call Detail Recording (CDR) and Station Message Detail Recording (SMDR) to provide a record for both IP and TDM based calls. CDR can be enabled for all calls (including trunk, tandem, and local), which allows billing for both local and long distance calls.

Virtually unlimited SIP trunking

SIP trunking using REDCOM’s TRANSip® technology suite with a REDCOM HDX Carrier Class 4/5 softswitch is a powerful way to build your business. SIP trunking is a secure, cost-effective way for rural service providers to leverage their IP network to provide voice service. SIP trunks deliver a significant return on investment and TRANSip-equipped HDX softswitches have extensive SIP trunking capabilities to ensure that your switching resources fit your business model for current and future growth.

SIP Trunking Made Easy

To get started with SIP trunking, all that is required is a TRANSip-equipped HDX — which includes a SIP Call Manager — and an IP network, and you will be on your way to implementing robust SIP trunking capabilities. SIP trunks are used to connect two switches together. As long as each switch has an IP address, communication can be made from one point to the other. With proper network assessment planning and implementation, SIP trunks can deliver high quality and reliable service with substantial cost savings.

Benefits of SIP Trunking for Service Providers

• Higher margins due to reduced install/configuration time
• Simplification of value-added services
• Powerful bandwidth control/savings
• Expansion into additional markets
• Support for wide variety of codecs
• More services delivered over the same pipe
