ASI-4E1 bidirectional adapter
ASI-4E1 bidirectional adapter is cost-effective signal adaptation device, and it is based on basis idea of transmission of digital television signal for design, and could make TS stream and E1 interface signal of SDH/PDH converted mutually, realize adaptation of heterogeneous network signal format. This network adapter could adapt 4-channel bidirectional E1, channel for the transmission of a set of standard-definition digital TV programs.
Features
