Methods, systems and devices for cascaded communications

A Performance Report Message or other message is received from a first device at a second device. The received message is revised such that a value of a Terminal Endpoint Identifier field in the message is revised according to a predetermined transformation, e.g., by incrementing the value in the Terminal Endpoint Identifier field. The revised message is then transmitted from the second device to a third device. The first, second and third devices may comprise devices of a wireless communications network, such as radio heads and/or a control part (COP). The message is preferably received over a first T1 link connecting the first and second devices, and the revised message is preferably transmitted over a second T1 link connecting the second and third devices. The revised message may be received at the third device, the revised value of the Terminal Endpoint Identifier field of the received revised message recovered, and a communications link and/or device to which the revised message pertains identified based on the recovered revised value of the Terminal Endpoint Identifier field, preferably in conjunction with a value in a Command/Response field in the received revised message.
