Next Generation Network: Voice and Video 5E Switching Solutions
Although the U.S. Federal Government is moving toward a more mobile and wireless workforce, wireline voice networks remain a critical part of non-classified communications. As the government directs more investment toward future telecommunications technologies, it is seeking cost-effective next generation network options for switch replacement and office consolidation.
The 5E Switch product family is a multifunctional, digital, time division multiplexed (TDM) switching system that links government communications devices into the public switched telephone network: this includes telephones, computers, faxes, data systems and other communications devices. With the capacity and flexibility to support multiple applications including wireline, wireless, voice, data and video, the 5E Switch product family provides more than 300 voice calling features to support an array of non-classified government applications.
The 5E Switch product family consists of the following:
- 5ESS (Electronic Switching System) -2000 Switch: supports a large number of users (more than 25,000 lines);
- CDX (Compact Digital Exchange) Switch: supports midsize user needs (8,000 to 12,000 lines) with remote switching unit requirements;
- VCDX (Very Compact Digital Exchange) Switch: for customers needing between 2,000 and 8,000 lines.
Remote wireline voice switching requirements are supported by 5E EXM-2000 (Extended Remote Switch Module) and 5E DRM (Distant Remote Switching Module). The EXM-2000 can be extended up to 600 miles from the hosting 5E network; the DRM can be extended up to 2,000 miles from the hosting 5E network.
System attributes include high-reliability hardware, software and data infrastructure; scalable ports and processing; multi-media interfaces; and node and next generation network configurations.
5ESS has a distributed modular architecture ensuing high capacity, reliability, remoting up to 2,000 miles from the host, and the ability to easily incorporate next generation network new technologies. Specific modules include the following:
Administrative Module (AM): one central point for operation, administration, maintenance and provisioning (OAM&P) of the switch
Provides interface to the people running the 5ESS switch to supply information on:
- Health of the switch
- Information on hardware
- Performs routine checks
- Office and billing records
Provides the ability to add/change/delete lines and trunks
- Stores critical information used by the switch
- Works with an element called a common network interface (CNI) ring and provides signaling information for calls going out of the switch
Communications Module (CM): low-delay tandem function; center-stage time slot and hunting that switches voice, data traffic and control messages between SM, CM and AM
- Manages physical interconnections that support communication between and among switching modules (SM) and the administrative module (AM)
- Distributes timing and synchronization data throughout the switch with speed
Switching Module (SM2000): autonomous operation; local or remote
Performs 95 percent of call processing functions including:
- Origination and termination of calls
- Feature control
- Routing calls
- Provides dial tone and calling features
Terminates subscriber lines and trunks
- Analog lines and trunks
- ISDN Lines (custom and national)
- Digital Lines (TR008 and TR303)
- DS1, STS-1, ADSL and OC3 trunk interfaces
- Converts analog to digital and digital to analog signals
Proven Successes with 5E Switch Product Family
LGS Innovation delivers an end-to-end turnkey voice solution: our team of engineers furnishes and installs all the hardware and software required to provide voice lines and trunks for the customer’s requested requirements.

5ESS is certified as interoperable with the Defense Switched Network (DSN) by the U.S. Department of Defense (DOD) Joint Interoperability Test Command (JITC) and the Defense Information System Network Security Accreditation Working Group (DSAWG). As a result, this product is on the DOD Approved Products List (APL).
The JITC-certified elements for the 5ESS Switch included:
- The full 5ESS switch configuration
- The cost-reduced compact digital eXchange (CDX)
- The very compact digital eXchange (VCDX) configurations
- The administrative services module (ASM)
- The eXtended switch module (EXM)
- The distinctive remote module (DRM)
Note: The EXM and DRM are remote switch units (RSUs) that feature fully functional operation in standalone mode.
The 5ESS switch has been a premier digital voice network solution for more than 30 years. This type of voice switch is designed on the TDM platform.
The 5ESS-2000 switch gives the customer total network flexibility. As U.S. Federal Government sites have varying voice network requirements, the 5E solution can be scaled for very small applications (e.g., 2,000 lines) up to large-scale applications (e.g., more than 25,000 lines).
LGS Innovations has deployed the 5E Switch product family for the following customers:
- Air Force: Tinker Air Force Base
- Army: Sierra Depot, Ft. Campbell, Ft. Benning, Ft. Riley
- DOE: Sandia National Labs, Livermore (Calif.), and Los Alamos; Lawrence Livermore National Labs, Hanford National Labs
- U.S. Treasury and other Civilian Agencies in the Washington, D.C. metropolitan area
