CONFIG: Rx Data Rx Data Rate
Rx Data Rate = 01544.000 kbps
Data Invert=Off
Use the top line to edit the Rx Data Rate. The bottom line permits selection of the Data Inversion
or the Clock Inversion features (added for compatibility with certain older equipment).
On the top line – Edit the Rx Data Rate by using the ◄ ►arrow keys to select a digit, and then
using the ▲▼ arrow keys to change that digit. Press ENTER.
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. When 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 framing or for G.703 interface type, the ▲▼ arrow keys scroll through
only the available data rates. When you edit the data rate to 1920 kbps while in D&I 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
kbps). See Chapter 3. REAR PANEL CONNECTORS
(Insert Data In), DDO (Drop Data Out) Connectors for AUX G.703 Data Rate Connectors
Reference.
Note that, in QDI (Quad D&I) mode, these data rates are read-only and data input is fixed at
OFF. The data rate is the sum of the tributary rates for all ports.
On the bottom line – Set the Data Invert or Clock Invert operation as On or Off by using the ▲
▼ arrow keys. Press ENTER.
