Wide Area Module Configuration

QuickSET Configuration Guide 17

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 N

ext>> button, and

go to the General Configuration section of this procedure.
