The result is easy and accurate setup. With the DSI 2008, all need for test tones, nulling adjustments and ducking adjustments have been eliminated. -
Page 6: Front And Back Panel Descriptions
Front Panel There is a power ON/OFF and call indicator at the left of the front panel. This indicator lights continuously when the DSI 2008 is turned ON and flashes when an incoming call signal is detected, if the call signal option board is installed.. The remainder of the front panel is divided into controls and indicators for the two separate hybrids, labeled SYSTEM A and SYSTEM B. -

Mounting Place the DSI 2008 on a desktop, or install it in an equipment rack using an RTS MCP Rack Mount Kit. Several rack mount options are available. There are no special ventilation requirements for the DSI 2008, but allow for ventilation around the power pack. -
Page 10: Audio Connections For The Other 4-Wire Communications Systems
Audio Connections for the Other 4-wire Communications Systems Construct 9-pin or RJ-11 cables to connect from the 4-wire system to the DSI 2008. To connect to the System A hybrid, use either J2A or J3A; for the System B hybrid, use either J2B or J3B. Pin connections are as follows:... -
Page 11: 2-Wire Audio Connections
Use standard TW intercom cables. Standard TW system cables can carry either one or two channels, while each hybrid in the DSI 2008 can only interface one TW channel to one 4-wire channel, which channel is determined by the front panel 2W CHAN SEL switch. If your TW system cable is only carrying one channel, or if you only need to connect one of two channels, connect directly to J1A (System A) or J1B (System B). -

This example uses GPI FIGURE 5. outputs #1 and #2 and GPI Input #1; however, you may use any other available GPI inputs and outputs. The Call Enable/Inhibit connection is optional. It gives you the ability to disable call signalling using a GPI output. However, when connecting to a Clear-Com intercom system, if an enable/inhibit switch is not connected, a jumper must be installed for any other application.

Page 17: Call Signal Connections For Other 4-Wire Communications Systems
4-wire Call Send and Call Enable/Inhibit The DSI 2008 accepts a switch-contact input from the 4-wire system and then generates a call signal output to the 2-wire system. The DSI 2008 also accepts an optional switch contact input to enable or inhibit call signaling between the 4-wire and 2-wire systems. -
Page 18: 4-Wire Call Receive
4-wire Call Receive The DSI 2008 receives call signals from the 2-wire system, then converts this to relay contact closure for use as a 4-wire call receive indication. The DSI 2008 also provides +5 VDC which can be connected to the relay contacts to generate a DC output signal instead of a contact closure. -

Page 21: Operation
The power indicator flashes when a call signal is received from a 2-wire line, if the call signal option board is attached. The DSI 2008 level displays should help to confirm which line is calling. Use the level adjust trimmers (Figure 8) to fine tune the listen levels. -
Page 22: Operating Notes For Adam, Adam Cs And Zeus Intercom Systems
Another way to generate a call signal is by assigning the GPI output as a level 2 talk key assignment for any key that is assigned to talk to the DSI 2008. However, this will cause the call lights to flash on the 2-wire line during the entire conversation. -
