A network element is provided comprising at least one switch, which is configurable to connect a subscriber line to a first service line or to a second service line, wherein the connection of the subscriber line to the first service line or to the second service line is configured via a signal conveyed across the second service line. Also, a system is suggested comprising several switches, wherein each switch is configurable to connect a subscriber line to a first service line or to a second service line, a control circuitry for controlling the several switches, an MSAN comprising several second service lines, wherein a dedicated service line of an MSAN is used for controlling the control circuitry. Further, methods for operating the network element or the system are suggested. |
