Cable Installation Safety Considerations
Interconnecting, communications, and Class 2 dc power cables should be separated from electrical light
or other Class I circuits by at least 2 inches. The exception is where Class I wiring or power circuits are
run in a raceway, or are metal-sheathed or metal-clad, or are permanently separated from the conductors
of the other circuitry by a continuous and firmly fixed nonconductor such as porcelain tubes or flexible
tubing in addition to the insulation on the wire. Communications cables and in-building wiring should be
listed and marked for the purpose according to NEC Article 800.
Telephone Line Lightning and Over-voltage Protection
The ICP9000 Navigator has an over-current phone line fuse that protects against occasional extreme fault
conditions that may get past the primary protectors. An example of such a fault condition is a power line
cross. For maximum surge and lightning protection, building primary (over-voltage) protectors should be
installed at the point where the telephone lines enter the radio equipment building. Primary protectors are
usually required by local codes and should be provided by your leased line provider.
Line Connections
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.
While using tone control, it is not necessary to have dc continuity on these lines. 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.
