General Maintenance For The Printer - IBM 1050 Reference Manual

Automatic Disconnect Feature
With the 103A type data set, this optional feature auto-
matically disconnects both terminals from the commu-
nications line when the System, Dial Disc switch at
either 1050 terminal is operated. This feature is de-
signed to permit the disconnect operation for both sta-
tions to be manually initiated at either terminal. This
feature must be requested from the common-carrier
prior to installation of the data set.
Note: To be effective, this feature requires that both data sets
have the "initiate Disconnect" and the "Respond to Disconnect
Option."
