Overview
The SB-22/PT and the SB-22A/PT are tactical, manual switchboards that can be rapidly installed to provide field facilities for interconnecting 12 local-battery telephone circuits, remote controlled radio circuits, or voice frequency (VF) teletypewriter circuits. Two SB-22/PTs may be stacked to provide a 29-circuit capability by removing one TA-221/PT (operator’s pack) and inserting five TA-222/PTs (line packs). Replacing a line pack with a trunk pack permits one-way ring-down, and one-way automatic trunk circuits between the SB-22A/PT and any other switchboard with common-battery signaling. The Tone-Signaling Adapter TA-977/PT provides the operator with a two-wire push-button tone-signaling capability for interfacing automatic switches without operator intervention.
