The ILS server is the core of the Vantage Dispatch Console System (DCS). The ILS manages InterTalk's logistics, including the call processing, audio stream switching, mixing, routing, and system health checks. When equipped with dual servers, the Vantage DCS easily achieves 99.999% redundancy on your network, and provides near-instant recovery in the event of an unforeseen disaster or disruption.
The ILS is configured in a standard web browser (Chrome, Firefox), using the ILS IP address. This allows easy remote access, control, and monitoring of the system, saving you valuable time in the field.
ILS servers can be located anywhere with network connectivity, and the number of ILS units is scalable to your agency’s network traffic requirements. Whether your needs are large or small, the Vantage DCS' versatility has you covered: A single ILS can easily power 1 to 100 console positions without any need for expansion.
Vantage DCS Workstation
The Vantage workstation PC is installed on each console position at the dispatcher’s seat, with a commercial-off-the-shelf (COTS) 22” or greater monitor. The Vantage DCS can be used via touchscreen UX, or mouse & keyboard, or both concurrently depending on the end user’s preference.
Audio Exchange (AUDx)
The Audio Exchange (AUDx) provides the Vantage system's IP streaming audio at each console. AUDx connects InterTalk’s speakers, headsets, microphones, foot switches, telephone, auxiliary audio and local I/O.
The InterTalk-manufactured AUDx uses advanced Digital Signal Processing (DSP) methods to set audio levels and to provide audio filters, routing, and automatic gain control (AGC) for microphone inputs, specifically designed for busy dispatch environments. With this full feature set, AUDx ensures your critical communications audio is robust and clear, and is not dependent upon the PC's soundcard or other audio hardware.
The AUDx features 4 speaker ports, 2 headset box connections, telephone headset connection, and a GPIO connection.
InterTalk’s Headset Box (HSB) connects to the Audio Exchange, and delivers PJ327 jacks for standard 4-wire/6-wire headsets, volume control, and a footswitch jack.
The Headset Box is fabricated with metal for rugged use in busy dispatch environments.
The InterTalk dispatch speakers provide Select/Unselect audio at the dispatching position.
InterTalk’s speakers have a volume control, and LED lights indicating the speaker status (power) and VOX (incoming audio).
Quad Line Interface (QLI) Card
The Vantage DCS radio endpoints are known as Radio Line Interface (RLI) cards. InterTalk’s current generation of RLI cards support up to four (4) radio interfaces, known as Quad Line Interface (QLI) cards. With 4 ports per card, the space savings for your agency is significant - a 3U rack space can accommodate up to 44 radio channels, providing excellent density for space savings.
Each interface can be 2 or 4-wire, with local PTT/COR control, and/or E&M signaling. Each of the four ports on the QLI is independent of the others, and all keying tones, paging tones, MDC-1200, GE Star, DTMF and other signaling is generated on a per-port basis utilizing advanced Digital Signal Processing (DSP) techniques. The codec used by the InterTalk System components, QLI inclusive, is G.711 μLaw compandered, providing an MOS quality of 4.0 or better.
InterTalk’s QLI Card has one RJ-45 Ethernet connector that supports 10/100baseT connection. The network protocols used are standard TCP/IP and UDP/IP that route through IPv4 equipment. The QLI can operate in parallel with existing equipment, allowing a seamless transition from legacy to new systems.
The QLI Cards use standard PCI-style card edge connectors that are rated for more than 200 insertions. Each QLI Card is equipped with its own switch-mode power supply regulators and transient protection devices to ensure excellent isolation from external environmental electrostatic discharge and power fluctuations.
The QLI utilizes a powerful DSP micro-controller to independently process both incoming and outbound audio across all four ports. The DSP processor generates outbound keying and alert tones, as well as paging sequences. Incoming signaling is decoded by the DSP, and Automatic Gain Control (AGC) level adjustment is applied.
Each port possesses a 2-wire output comprising the summation of the input and output audio paths with or without signaling. The output is designed to interface with a 3rd party archival recorder. Nominal level is -10 dBm, and can be adjusted by a System Administrator.
InterTalk’s QLI Cards run an embedded distribution version of the Linux operating system (uClinux™). uClinux™ provides the ability to remotely view all card parameters, including the current status of the application, card health, and remote maintenance and diagnostics by the System Administrator or technician.
