WAN Applications

The Sync Port ConÞguration window contains the following Þelds:

Type

Displays the type of connection used at the port. Click the associated button to select RS422, RS232, V.35, and Other. You can change the type of connection displayed in this window to match the conÞguration of your physical synchronous port.

Inspeed

Displays the speed of input communications of the synchronous port. Click the associated button to select 2.048 Mbps, 1.54 Mbps, 256 Kbps, 128 Kbps, 64 Kbps, 56 Kbps, 38.4 Kbps, 19.2 Kbps, 14.4 Kbps, and 9.6 Kbps. The selected inspeed will appear in the button in bits per second (bps) format.

Outspeed

Displays the speed of output communications of the synchronous port. Click the associated button to select: 2.048 Mbps, 1.54 Mbps, 256 Kbps, 128 Kbps, 64 Kbps, 56 Kbps, 38.4 Kbps, 19.2 Kbps, 14.4 Kbps, and 9.6 Kbps. The selected outspeed will appear in the button in bits per second (bps) format.

NOTE

The Inspeed and Outspeed are determined by the CSU/DSU attached to the synchronous port. If you change the Inspeed or Outspeed displayed in this window, it will not have an effect on the actual transmit or receive speed of the connection. If the communication speeds do change, you should change the values in this window to reßect these changes.

Clock Source

Displays the source of the portÕs bit rate clock. The clock source will always be External on a synchronous port.

State Change

The bottom half of this window displays the trafÞc for individual signals on your synchronous port. The trafÞc signals are: CTS (Clear to Send), DSR (Data Set Ready), RTS (Request to Send), and DTR (Data Terminal Ready). The red and green indicators reßect whether the indicated signal is disabled (off) or enabled (on), respectively. The State Change text box to the right of each of these Þelds will display the number of times the signal has changed state from enabled to disabled, or vice versa.

To modify the synchronous port parameters:

1.Click on the Type, Inspeed, or Outspeed command buttons.

2.From the Type, Inspeed, or Outspeed drop-down menus, select the new parameter.
