90 CSX400 and CSX400-DC User’s Guide
Sync Clock Speed — Displays your configured receive clock speed. The default setting for this
field is 64000 bits per second. The information necessary for you to set this field is normally
determined by the service provider. Select the down arrow button to make your selection from the
list of clock speeds using the information provided by your service provider (if it is not listed, type
the value in).
Sync Flow Control — Displays the source of the Clear To Send (CTS) and the Force Data Set
Ready (DSR) signals.
The CTS signal is an input to the CSX400. The CSX400 can either use or ignore the CTS signal.
Clicking on the box indicates that the CSX400 ignores the CTS signal from an external DCE (Data
Communications Equipment) and forces the signal high. The off setting indicates that the CTS
signal is received from an external DCE. The default setting is off.
The DSR signal is an input to the CSX400. Clicking on the box indicates that DSR signal is
internally forced high. The off setting indicates that the DSR signal is received from an external
DCE. The default setting is off.
Protocol — Displays the active protocol for the Wide Area Sync port. The selections for this field
are either Frame Relay and PPP. The default setting for this field is PPP.
Link Management Protocol — If Frame Relay is the selected protocol, this field displays Q.933
Annex A and T1.617 Annex D. The default for Frame Relay is T1.617 Annex D. This field is
grayed out and not used for PPP.
Once the Wide Area Synchronous configuration is complete, click on the N
ext>> button, and go to
