Line Considerations - Private Circuit
If leased lines from your local telephone company are used between the console and a tone remote
adapter or base station, the telephone company (Local Exchange Carrier) may request a Facility Interface
Code (FIC). The FIC is subject to local availability. See Table 1.
Table 1. Analog Facility Interface Code
FIC Description
02NO2 2-wire private line; no signaling conversion by LEC (IN-Band)
02NO4 4-wire private line; no signaling conversion by LEC (IN-Band)
Metallic 2 or 4-wire metallic private line (“Hoot and Holler” circuits)
Within a manufacturing plant, a campus, or large building, customer-supplied metallic pairs may be used.
It is not necessary to have dc continuity on these lines. While using tone control, continuity is required
for dc control.
Circuit Conditioning
The console 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). 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 2-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.
