c. Ensure both telephones have the MODE SELECTOR switch in POINT-TO-POINT and the
BATTERY switch to LB.
d. Point-to-point operation. Lift the handset of either telephone. The other telephone should
ring one time and the CALL indicator should light. If there is no answer, press down the
HOOKSWITCH and release it to send another ring. Once the party answers, you can have a two-way
conversation. When you finish, just place the handset in the cradle being sure to place the handset on
the HOOKSWITCH to clear it.
21. Operating with a switching facility. In order for the telephone to operate with a switching facility,
you must know if the system is working DC or AC. Then you must set the MODE SELECTOR switch
and the LB/CB switch to their proper positions. In addition, WF-16/U telephone cable must he
connected, usually to a J-1077A/U, to get the signal to the facility. You would connect the green
conductors to the G and B terminals on the C42 connector block and to pair 1 of the J-1077A/U. You
would have to connect the brown conductors to the R and Y terminals of the C42 block and to pair 2 of
the J-1077A/U. Odd pair transmits, even pair receives.
a. An incoming call is signaled by the normal series of tone and silence. The type of call is
determined by the rates of tone and silence. A routine call has two seconds of tone followed by four
seconds of silence. Any priority call has one second of tone and one second of silence. The visual ring
indicator lights at the same rate as the tone. Simply lift the handset and have your conversation. Be sure
to place the handset back in the cradle on the HOOKSWITCH to release the line.
b. An outgoing call is rather easy. Remove the handset from the cradle and listen for the dial
tone. Press and release the numbered keys on the keysender pad, one at a time, for the number being
called. If a mistake is made, press and release the HOOKSWITCH and try again. Listen for a ringback
or busy signal. If a busy signal is heard, replace the handset on the cradle and try again later.
c. When assistance or information is required, an operator can be called using the following
procedure. Pick up the handset and listen for the dial tone. Press and release the 0 (zero) key on the
keysender pad. Listen for a ringback or a busy signal. If the operator answers, obtain your information.
If the operator connects you to another person and you need more assistance, use the R key. Press and
hold the R key until a recall response is heard. Release the key and wait for the operator to answer the
recall. There will not be a ringback or busy signal for an operator recall.
