The Cisco 4PT-KIT-T2 is a Cisco 4-Port T2/E2 Packet Voice Trunk Network Module Kit. It’s designed to provide T2/E2 connectivity for Cisco Integrated Services Routers (ISRs), enabling voice and data integration over traditional telecommunications lines. This kit allows the router to connect to T2 or E2 circuits, which are digital telecommunications lines used for carrying voice and data. It’s used in environments where connectivity to traditional TDM (Time Division Multiplexing) networks is required. The “KIT” designation often implies that the module is supplied with necessary cables and accessories.
