ITR2000A Tone Remote Desk Set Installation
17 02/12
Line Connection
Connect the telephone line to the modular connector located on the back of the desk set. Refer to the
pinout on page 6 in the “Description” section. The six-pin modular jack is a full/half duplex connection
to the line. The CARD Suite Programming Software allows selection of a four-wire type of connection
to the line. In the two-wire mode, the hybrid will be auto-balancing. An average of ten desk sets can be
connected in parallel, depending on the system design. The maximum loss between any two desk sets or
between a desk set and the station should not exceed 20 dB. Desk sets are shipped with line terminations
active. With parallel units connected, only the farthest desk set units should be terminated. Observe
right to left pinout for pins 1 through 6.
Line Considerations - Private Circuit
If leased lines from your local telephone company are used between the ITR2000A and the ITA2000A or
similar tone remote adapter, the telephone company (Local Exchange Carrier) may request a Facility
Interface Code (FIC). The FIC is subject is to local availability.
Analog Facility Interface Code
FIC Description
02N02 Two-wire private line; no signaling conversion by LEC (IN-Band)
02N04 Four-wire private line; no signaling conversion by LEC (IN-Band)
Metallic Two- or four-wire metallic private line (tip, ring, and sleeve circuits)
Within a manufacturing plant, a campus, or large building, customer-supplied metallic pairs may be used.
Metallic pairs must be used if the dc control option is installed. It is not necessary to have dc continuity
on these lines.
Circuit Conditioning
The desk set is designed to work with good-quality analog speech band or leased private circuit. This
was previously known as ‘basic’ conditioning under Series 2000/3002 service.
 The line must be non-PSTN (no dial tone, talk-battery, or signaling).
 Less than 20 dB line loss should exist from the ITR2000A to the tone panel.
This equipment falls under the Category II, FCC Tariff #260 Service and is exempt from FCC Part 68
registration. (Ref. FCC Form 730 Application Guide pages 1–5.) For two-wire operation, 2000 Series
lines may be used with or without conditioning. C1 or C2 conditioning is available for these lines and
relates to the envelope delay distortion and attenuation. A basic conditioned line may be used if it is the
only type available. Overall system quality is limited by the quality of these lines.
Audio Accessory/RS-232 Port Connection
Use the eight-pin audio accessory/RS-232 port to connect a PC to the ITR2000A with the proper
connecting cable in order to use the CARD Suite Programming software. See the “CARD Suite
Programming Software” section of this manual for instructions on set up.
After programming is complete, connect an audio accessory, such as a desk microphone, gooseneck
microphone, boom microphone, headset, or footswitch, if desired. The microphone input type is passive,
with an input impedance of greater than 2k ohms and a nominal input level of −20 dBm. Refer to the
audio accessory/RS-232 port pinout on page 6 in the “Description” section.
