Description
The CS61884 is a full-featured octal E1/T1/J1 short-haul LIU that supports both 1.544 Mbps or 2.048 Mbps data transmission. Each channel provides crystal-less jitter attenuation that complies with the most stringent standards. Each channel also provides internal AMI/B8ZS/HDB3 encoding/decoding. To support enhanced system diagnostics, channel zero can be configured for G.772 non-intrusive monitoring of any of the other 7 channels’ receive or transmit paths.
