A method and apparatus for serving selected lines and trunks from two or more switches. The selected line and trunks are connected to peripheral units each served by two or more switches. The switches each maintain translation information and the supervisory states of the selected lines and trunks. Advantageously, at low cost, the selected lines and trunks can be provided with service even when one of the switches is out of service.
