CH1840 Datasheet, PDF (5/7 Pages) List of Unclassifed Manufacturers – Low Profile Data Access Arrangement (DAA) Modules

Mounting the CH1840
The CH1840 can be soldered directly to the host circuit card or
installed in sockets. Direct soldering provides the most sound
connection. To avoid the problems of flux contamination, hand
soldering is preferred to wave soldering. Many socket manufac-
turers offer socket strips that accept the 0.025 inch square pins
on 0.10 inch centers. When using mechanical sockets, restraint
of the CH1840 should be provided to keep it seated during ship-
ment. Plastic cablewraps are secure yet easily removed.

FCC NOTICE TO THE USERS
1. UPON REQUEST ONLY, you must provide the following data to
your telephone utility company (telco):
a) Notice of intention to install or permanently remove an FCC
Part 68 registered device or system, and the *FCC Registra-
tion Number.
b) *The Ringer Equivalence Number (REN) (see device label).
Note that if several devices are connected to the same line,
the RENs must not add up to more than 5.0 (A or B). This
REN figure is important to your telco.
c) *The (USOC) jack type to be provided by the telco. Typically
this will be RJ-11C/W for single lines.
*The *-flagged items above are noted on the equipment’s
FCC Compliance label.
2. This device may not be used on telco-operated coin phone
lines. Party lines and privately owned coin-phones are
subject to local State regulatory policies, and possible
additional State special requirements.
3. The telco has the right to make changes to its network which
may affect the operation of your equipment, provided you are
given adequate advance written notice to permit correct oper-
ation.
4. In case of operational problems, disconnect your unit by
removing the modular plug from the telco jack. If your regular
phone (or other device or system) still works properly, your

and (officially) serviced or returned for repairs. If upon the
above connection, your regular service still has problems,
notify your telco that they may have a problem. Request
prompt service at no cost to you the user. If a problem is
found in premises wiring not telco-installed, you are subject
to a service charge. If a fault is in telco-installed wiring, you
may be subject to a service call charge.
