Federal Communications Regulations
FCC (Part 68) Regulations Governing the Operation
and Maintenance of IBM 2400 bps and 4800 bps
Integrated Modems (Sales Features 5641 and 5741)
over the Public Switched Network in the US
Data protective circuitry in the IBM 2400 bps and the
IBM 4800 bps Integrated Modems is registered with the
US Federal Communications Commission (FCC). The
FCC requires that IBM publish the following information
about the operation and maintenance of all devices
containing registered circuitry. The FCC also requires
that all persons who use and maintain devices
containing registered circuitry in the US comply with the
following FCC rules:
1. To ensure compliance with the regulations
regarding the repair of registered circuitry, field
repair is limited to replacement of field-replaceable
units only.· Field replacement of these units will be
performed by authorized personnel only. No other
field repair or adjustment to the registered circuitry
is permitted.
2. If a problem occurs that is determined to be in
registered circuitry or to be caused by registered
circuitry, the device containing that circuitry must
be disconnected from the public switched network
immediately by removing its System/38 cable
from its network data jack.
If the telephone company detects a problem on
the network that has been caused by System/38,
the telephone company has the right to temporarily
discontinue service to the device containing that
circuitry. Service may be discontinued immediately
and remain discontinued until the problem no
longer exists.
3. Connecting a device containing registered
protective circuitry to a party line or to a line
serving a COin-operated telephone is prohibited.
iv
4. The telephone company may make changes in its
communications facilities, equipment, operations,
or procedures, where such action is reasonably
required in the operation of its business and is not
inconsistent with the rules and regulations of the
FCC. If these changes can be reasonably expected
to cause your equipment to be incompatible with
the telephone company's communications facilities,
or to require modification or alteration of your
equipment, you will be given adequate advance
notice, in writing, to allow you an opportunity to
react in a manner that allows you to maintain
uninterrupted service.
5. Before a device containing registered circuitry is
initially connected to the publiC. switched network,
you must contact the telephone company and
supply the following information:
6.
a. The line to which the device is being connected.
b. The FCC registration number and ringer
equivalence number of the device.
c. The identification of the product containing the
registered circuitry. In the case of the
System/38, you will identify the product as the
IBM 5381.
d. The type of communications line jack needed.
See
Cable Instal/ation Responsibility
in this manual
for information about the FCC registration number,
ringer equivalence number, and type of jack to be
reported for Sales Feature 5641 or 5741.
You also must inform the telephone company of
all registration numbers associated with other
devices that you may have connected on this
circuit.
You must notify the telephone company upon final
disconnection of a device containing registered
circuitry, identifying the line from which the device
was disconnected.
