2.1.2. Requirements for the communication line
To ensure normal operation of the modems and the specified values of the
performance characteristics, the line must meet the following requirements:
•
The cable must have neither core-to-core bridges nor ground
leakages, or leakages to other conductors including those not
hooked up to anything. The line must not have branches.
•
Cores of a multi-pair cable must be taken from the same pair.
•
Parallel connection of several pairs (for instance, in order to
reduce
the
active resistance) is not permissible.
•
Failure to meet the above requirements may cause degradation
of the characteristics or even complete disability of the line.
•
Using modems in either aerial or combined
(undeaerial) lines is forbidden .
Warranty will become null for the modems operated at aerial or combined
(undeaerial) lines.
After you have made sure that the communication line meets the above
requirements, take the following steps:
•
Place the RJ-45 plug on the cable, according to (Fig. 7). Modem
Sigrand SG-17B uses only one pair of wires, pins 4 and 5, the
other pins are not used..
•
Connect the cable socket to the DSL socket of the modem.
