When setting the EST-9600 to Internal Clock source, also set the rate. The Encoding, menu
selection 3, defaults to NRZ (non-return to zero). This is typical for PPP, Frame Relay, X.25 data.
NRZI is often used with IBM SDLC protocols.
After making all the necessary changes, select item 8 from the main menu, “ Save and Activate”.
Remember that after changing the IP address, if the EST-9600 is again accessed for setup via telnet
or a web browser, it is necessary to change the address of the PC to match the IP subnet of the EST-
9600.
