    摘要: A telecommunication switch and an operating method for handling SDH signals transmitted by a protection SDH link associated to a working SDH link of an SDH hardware interface of the telecommunication switch. The telecommunication switch comprises a plurality of SDH hardware interfaces and an equipment protection arrangement. Each of the SDH hardware interfaces is connected to the equipment protection arrangement by a first and a second SDH connection. A protection SDH link of a first SDH hardware interface is connected to a second SDH hardware interface. The second SDH hardware interface is designed to forward protection SDH signals transmitted by the protection SDH link to the equipment protection arrangement using its first SDH connection. The equipment protection arrangement switches the protection SDH signals to a spare SDH termination module or an SDH termination module connected to the first SDH hardware interface according to a protection switching control signal.

    摘要: This invention relates to a telecommunication switch (10) and an operating method for handling SDH signals transmitted by a protection SDH link associated to a working SDH link of a SDH hardware interface of the telecommunication switch. The telecommunication switch is comprising a plurality of SDH hardware interfaces (1,2,3,4), each comprising working link connecting means (11), being designed to be connected to a working SDH link (12) and protection link connecting means (13), being designed to be connected to a protection SDH link (14) associated to the working SDH link of the SDH hardware interface, wherein to each of said SDH hardware interfaces a SDH termination module (20) is connected, and—an equipment protection arrangement (30), comprising a protection switching hardware module (31) and a spare SDH termination module (32). Each of said SDH hardware interfaces (1,2,3,4) is connected to said equipment protection arrangement (30) by a first SDH connection (15) and a second SDH connection (16), and the protection SDH link (14) of a first SDH hardware interface (1) of said SDH hardware interfaces (1,2,3,4) is connected to a second SDH hardware interface (2) of said SDH hardware interfaces (1,2,3,4). The second SDH hardware interface (2) is being designed to forward protection SDH signals transmitted by said protection SDH link (14) of said first SDH hardware interface (1) to said equipment protection arrangement (30) using its first SDH connection (15) and said equipment protection arrangement (30) is being designed to switch said protection SDH signals to said spare SDH termination module (32) or the SDH termination module (20) being connected to said first SDH hardware interface (1) according to a protection switching control signal.
