What are you talking about?
The attractive, ergonomic control surfaces offer two operational modes, selectable with a flip of a switch:
Call screening and control are available from any networked computer, using a standard web browser, with the included STAC IP. With STAC IP, your talent can host their shows from anywhere there is an Internet connection or you can economically create more control points from any computer on your local network. No additional computer is needed to serve the STAC IP webpage, as it is served from the mainframe. Your connections are secured by password protection and no dedicated client software needs to be installed. In addition to replicating the call status information on the control surfaces, STAC IP also provides fields for additional information about callers and text “chat” among those on your show network. We have implemented a demo
of the STAC IP. This link is to an actual working STAC system at our
facility in Massachusetts, USA. The firmware is in a "beta"
state at this time and improvements are ongoing. The demo works best via
Internet Explorer with any pop-up blockers disabled. The username can be
anything you like but the password is comrex (lowercase) Alt-F4 will
exit the full screen mode. For a demo of the STAC IP, click
here. The STAC12 mainframe and control surface are configured for 12 phone lines, while the STAC6 is configured for six lines. Expanding a STAC6 to a STAC12 in the field is quickly accomplished by installing a mainframe extension card and control surface “sidecars”. No matter what you’re talking about, you’ll be talking about quality, convenience and value when you put the Comrex STAC on the line. |

No configuration required after initial installation. Set-up controls are behind an easy-access panel and include pots for level adjustments and DIP switches for configuring Auto Attendant, auto-disconnect, automatic audio gain control, VIP and other settings.
Front panel features three bicolor LEDs indicating level status of audio input and hybrid levels.
Telephone line connections provide loop-thru to other systems or telephone sets sensing loop-thru provided for PBX interconnection. Callers are conferenced within the STAC mainframe requiring only one mix-minus audio input to feed both hybrids.
A separate audio input is used
for program-on-hold. Each hybrid has an individual audio output to send to
your audio
mixing console or router.
A third audio output sums the two callers with the host audio—great for connection to a recording device.
Ethernet port allows the integrated web server to deliver call screening info and to control all call functions via STAC IP.
Software is field upgradable
via compact flash port.

One control surface is included with purchase of mainframe. Additional control surfaces, up to four per system, may be added at any time. STAC6 control surfaces can be upgraded to STAC12 in the field.
Clean, logical design allows functions to be mastered quickly. Dedicated buttons, with associated multicolor LEDs, minimize the number of button presses and make it easy to determine status of phone lines and callers.
Any control surface can operate in Studio/Producer or Screener Mode.
Designed to use standard Cat-5 wiring to link the control surfaces to the mainframe. No proprietary cabling or additional power source required for control surface connection.
Common STAC control surface functions available in both Studio/Producer and Screener Modes:
— Callers on hold who have been screened,
— Followed by callers on hold who have not been screened, in order of length of time on hold.
Screener Mode functions:
The top row of buttons
performs off-air call answering, including placing calls on hold or
releasing them. Callers selected from these controls communicate via the
control surface handset. Bicolor green/yellow LEDs indicate whether the
line was answered at this control surface or another.
The middle row of buttons
is used to signal screening status to studio/producer control consoles,
place callers on hold and to change priority. A screener cannot place
callers on air. Bicolor red/blue LEDs indicate which lines are on hold,
which lines are on screened hold, and priority status.
The bottom row of buttons drops lines that have been selected using the top row of buttons.
• Duplicates control surface functions on any network-connected computer using
standard web browsers.
• Password protected access to talent, producers and screeners on existing
local networks and Internet connections.
• Software is served from STAC mainframe, so no dedicated server is required.
• Call timers are displayed for each line, showing length of time on hold
and length of time on air.
