Telephone switchboards can be connected together in a process called "trunking" to form a larger network. Trunking allows for call transfers and interconnection between multiple switchboards.
To connect switchboards together, you would need to establish physical connections using dedicated trunk lines or digital connections (such as T1 or E1 lines). These connections would then be used to route calls between switchboards.
Once the physical connections are in place, the switchboards would need to be configured to recognize and route calls to the appropriate destination. This can involve programming the switchboard's routing tables or configuring the systems to use a centralized call routing server.
By connecting multiple switchboards together, you can create a larger telephony network that can handle a higher volume of calls and allow for seamless call transfers between different locations or departments.
