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 CyberSWITCH or HSIM. The CyberSWITCH or HSIM can
either use or ignore the CTS signal. Clicking on the box indicates that the CyberSWITCH or
HSIM 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 CyberSWITCH or HSIM. 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 interface. The Protocol panel lets you
select either Frame Relay or Point-to-Point.
Link Management Protocol —
If you selected Frame Relay protocol, this field displays
Q.933 Annex A, or T1.617 Annex D. The default is T1.617 Annex D. This field is grayed out and
not used for PPP.
When you have completed Wide Area Synchronous configuration, click on the Next>> button, and
go to the
General Configuration section of this procedure.
