Here are some more vintage sounds that are uncategorized.
A busy signal, possibly from a Number 1 Crossbar or a Panel office.
The sound of someone making a telephone call on old Number 5 Crossbar (#5XB) office. You hear the dial tone, the sound of a rotary dial, and the ring back signal.
A combination of several things in one phone call. You hear the sound of an “empty” line, then dial tone and dialing a call to a supervision test. This is originating from a #1XB, routing thru a XB-Tandem (listen to the MF), and terminating in a Panel office. Listen to the rapid clicks of the “revertive pulsing” from the Panel Office to the XB-Tandem.
