3 MediaPro s high density design and built in distributed multi-media switching and processing capabilities reduces communications system size, weight and power requirements to a fraction of that required by previous generation technology. MediaPro s low power consumption and industrial rated operating environment specifications result in reliable operation for mission critical applications worldwide. Voiceboard MediaPro provides an open architecture, enabling your choice of CPU/server and operating system. Close integration between the application CPU and MediaPro s embedded switched communications I/O allows for higher density systems, greater applications flexibility and more straightforward expansion capabilities than previous generation architectures. MC 2 Military Call Control Software MediaPro MC 2 Call Control software is a performance optimized application software platform capable of implementing a wide variety of real time military communications scenarios. The core of MC 2 is a highly configurable call processing state machine written in portable ANSI C ++, coupled with hardware configuration and scenario scripting software. MC 2 software is embedded on Voiceboard s BridgeWay Radio Network Control card. MC 2 is compatible with all Mediapro hardware interfaces to the PSTN, radios, POTS telephones, Vo connected PC s, telephones, encrypted communication devices, and PBX or legacy telephones connected via T1/E1 PRI ISDN spans, FXS/FXO and E&M tie lines. Voiceboard offers MC 2 as a custom tailored product to meet your specifications. Most custom call processing applications can be met via modifications to Voiceboard s foundation MC 2 script and web browser GUI. MC 2 standard product delivery includes customized MC 2 application, foundation application script and web browser binary downloads. The MC 2 documentation package includes state table diagrams, a hands-on training class and technical support credits. Voiceboard professional services provides timely product R&D, enhancement and training services. Foundation script configurations are available for many common applications, including programmable switch, large scale distributed conferencing, multi group intercom, multi group radio monitoring, Vo gateway, radio control interface, PBX and IVR.

5 Networked Tactical PBX/Intercom Voiceboard MediaPro can be programmed as a full-featured tactical PBX system. Features once requiring the integration of separate systems, such as radio interface, large party conference, intercom, radio monitoring, voice messaging and gateway, can easily be integrated into the system design. LAN integration and embedded switching features result in highly flexible and scalable PBX s. Phones Analog and Digital Phones Satellite Communications LAN Radios BridgeWay Control Terminal(s) Operator GUI Packet Voice Fiber Packet WAN T1/E1/J1 PRI ISDN Network Conventional PBX The wide variety of available MediaPro network interfaces and signaling protocols permit straightforward connection to PRI ISDN, PSTN or tandem networks. Signaling protocol stacks may be modified to accomodate custom handset design and interworking between other communications systems. The MediaPro software API permits direct control of system switching functions, allowing for implementation of specialized user Class of Service, MLPP and priority routing features. On board DSP s may be used to support Vo, telephony signaling, conference and intercom functionality over packet networks and Ethernet LANs. MediaPro MC 2 provides the following PBX features. These features are available to all supported interface types, including POTS, FXS, FXO, radio, digital trunks and telephone terminals. POTS, FXO, FXS, radio, digital trunk, telephones and other terminal types Call forwarding DTMF, MF and call progress tones Voice announcements POTS and operator consoles Individual line circuit class-of-service Preset and meet-me conferencing Intercom Caller ID Vo Priority override Huntgroup Hookflash and hold

6 Radio Networked Communications Systems MediaPro based communication systems allow distributed and remotely operated intercom and monitoring positions to communicate with each other and interconnect with a wide variety of external radio equipment, recorded media, military or commercial networks and PBX systems. Distinctive right-left headset feeds reduce user workload during periods of heavy traffic. Audio channel keying capabilities include VOX, PTT and RTP packet detection, with desired radio channels switchable under software control. Mixing features allow individual gain control of each channel, as well as a selection of channels to be monitored. Numerous standard DSP based audio compression techniques may be utilized to reduce storage media or networking bandwidth requirements. When voice logging is required, compression of up to 8X may be utilized while still maintaining toll quality audio. VOX detection allows termination of recording during periods of silence. Recorded channels may be time-stamped for reference. The MC 2 radio interface is designed to support the demanding requirements of tactical military operations, including mobile, shelter, airborne and marine theatres of operation. MC 2 radio interface features include: Remote radio control from laptop Transformer isolated interface Transmit on/off keying control lines VOX and squelch DTMF keypad signaling Multi-channel Radio conferencing Universal audio level adaption Individual channel gain control Multi-channel mixing Direct dial Vo Gateway Voiceboard Voice over (Vo) Gateway provides call control, call switching, BridgeWay resource management and embedded H.323 or S protocols. Vo Gateway Functionality: Implements H.323/H.245 and S protocol call control functions Multiple security modes Supports multi-host TCP-UDP/ protocol and redundant operation Integrated CAS, R2 and ISDN signaling Management and configuration of local TDM connections Management of to PSTN address translation Multicast capability Vo Features: G.711 u/a-law PCM G /32/24/16 Kbps ADPCM G.729 A/B 8 Khz toll quality CS-ACELP G IMTC Compliant - 5.3/6.3 Kbps DTMF Detection and Generation Caller ID, V.25 Answer Tone, V.21 CNG Call Progress Detection and Generation, AGC G Echo Cancellation, 128 ms tail Voice activity detection and comfort noise Jitter Buffering and lost packet recovery Play/record of Audio Files RTP Packetization

7 Training/Simulation Systems MediaPro integrates DSP audio processing, switching, network connectivity and signaling on a single card, replacing the several separate chassis of equipment required by previous generation training system designs. The close integration of MediaPro functions improves system performance and simplifies implementation. For example, ISDN signaling or data messages between remote and central training sites provides positive, rapid control of radio transmit channel keying, eliminating the delays associated with VOX transmit control. DSP based audio compression allows the use of analog land line modem connections between sites when T1/E1 services are not available. Voiceboard s MediaPro products add realism to simulation systems. Audio feeds may be blended under host control permitting recorded channels to be merged with control station audio to provide a realistic environment. Flexible expansion and large party conference features permits networking thousands of participants between local and remote facilities. On demand record/play capabilities allow review and study of previous events. Full workstation control permits instructor intervention at any level required.
