One embodiment of the disclosures made herein is a network equipment protection module configured for being removably mounted on a network equipment protector block. In accordance with such a network equipment protection module, the network equipment protection module includes surge protection circuitry configured for providing surge protection functionality, AC coupling-DC blocking circuitry configured for providing AC coupling-DC blocking functionality and DC blocking circuitry configured for providing DC blocking functionality. The DC blocking circuitry enables the DC blocking functionality to be selectively activated and deactivated. In this manner, such a network equipment protection module enables the combination of surge protection, DSL signal transmission, full metallic loop testing (MLT) and bridging of a DC voltage to be facilitated in association with a twisted pair transmission line.
