InterTalk DCS Components
The ILS server is the core of the InterTalk Dispatch Console System (DCS). The ILS manages InterTalk’s logistics, including call processing, audio stream switching, mixing, routing, and system health checks. When equipped with dual servers, the InterTalk 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 InterTalk DCS’ versatility has you covered: A single ILS can easily power 1 to 100 console positions without any need for expansion.
InterTalk DCS Workstation
Audio Exchange (AUDx)
The Audio Exchange (AUDx) provides the InterTalk system’s IP streaming audio at each console. AUDx connects InterTalk’s speakers, headsets, microphones, footswitches, 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, a telephone headset connection, and a GPIO connection.
Citadel IP Radio Gateway
The Citadel IP Radio Gateway serves as the connection between non-IP radios and your network. InterTalk’s Citadel IP Radio Gateway can be used to construct nearly any type of voice or data radio network. It converts any audio from up to four (4) conventional radios or phones and sends it to your console system(s) and radio sites at your agency, and vice versa.
The Citadel can be customized to meet your exact communications requirements in the field, and also allows you to remotely control gates, doors, lighting, alarms, generators, or anything else connected to your network.
The Citadel can connect to and control base stations via GPIO (parallel port) connections, with additional ports available to control radio units using RS-232/422/485, USB or Ethernet. The Citadel can control up to four (4) base stations using a single IP connection with TCP/IP for control, and RTP/UDP/IP for voice streaming.
Where no IP backhaul facilities exist, the Citadel can be configured for analog trunk operation by using one of the analog ports as drop-and-insert style trunk connections.
The Citadel also enables an extended network of conventional repeaters to work together over a wide area. While analog trunks can be used, IP connections between the sites allow for advanced features such as peer-to-peer receiver voting, transmitter steering, and talker identification. With the addition of the InterTalk Dispatch Console System, a small and very functional radio network with advanced features can be built for less than the cost of a typical P25 system controller.
The Citadel’s DSP technology, accompanied by its built-in Linux operating system make it easily modifiable for any job you can think up for your site. Coupled with a best-in-class input and output offerings, an extreme temperature range tolerance (-40°C to +65°C / -40°F to 149°F), and a significantly lower power requirement (3W nominal), our Citadel Analog Radio Gateway is the smartest, most economical choice for your remote, battery/solar-powered radio site requirements.
Quad Line Interface (QLI) Card
The InterTalk DCS radio endpoints are known as Radio Line Interface (RLI) cards. InterTalk’s current generation of RLI cards support up to four 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 signalling. 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 signalling 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. The DSP decodes incoming signalling, 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 signalling. The output is designed to interface with a 3rd party archival recorder. The 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.
InterTalk’s Dispatch Console System and our console equipment is engineered to the highest standards and is the most comprehensive dispatch console available.
