The maximum limits for the Rx Data Rate are 18kbps to 25Mbps. The actual minimum and
maximum data rates are dependent on Framing mode, Interface type, Modulation type and FEC
Code Rate. If you change any of the higher-priority parameters – causing the data rate to
become invalid – the Data Rate adjusts automatically. The installed FAST option(s) also dictate
the upper range of data rate.
When configuring for D&I or IDR framing or for G.703 interface type, the

framing, a message appears to indicate that E1 Fixed Channel Mode is implemented.
When G.703 is used, three auxiliary rates – 512, 1024, and 2048 kbps – are available as indicated
by the word AUX appearing to the right of the decimal place (for example, 00512.AUX
