What istandem office

A tandem office is a phone switching center that provides connections between offices within the same network or between different networks. Unlike end offices that work with client lines, a tandem office only handles trunks and does not have customer-to-customer connections. These offices are used by Regional Bell Operating Companies (RBOCs) to manage intraLATA toll calls and provide access to interLATA toll carriers.

Class 4 tandem offices were transferred to AT&T after Divestiture, while Class 5 local tandem offices remained with the RBOCs. These offices are typically located in the same building as end offices and may even share a switch.
