Several customized I-O connector solutions have been developed for E1/T1 and xDSL applications, including a cable connector and a board connector solution. The E1/T1 transmission protocol is used to transmit voice and data between devices and runs at a speed of 2 Mbit/s. ASDL and VDSL solutions run at higher speeds, up to 100 Mbit/s and are capable of supporting new high bandwidth applications. Range consists of solutions from 8 up to 72 pairs per connector and are designed to connect to cost-effective shielded cable operations.
