Dsr Enable
This Þeld displays whether the Dsr (Data Set Ready) signal is enabled. If the Dsr
signal is enabled (Yes), the device will use it to determine the status of the
connection. If the signal is disabled (No), it will be ignored.
Configuring the Synchronous Port
You can conÞgure your synchronous port as follows:
1. To change the Port Type, click on the selection box and a pull down menu will
appear. Select V.35, Rs422, Rs232, or None as appropriate, and release the
mouse button.
2. To change the In Speed or Out Speed, highlight the current speed and type a
new value in the text box.
3. Click on to save the changes or to go back to the original
configuration.
The new synchronous interface conÞguration will be displayed in the window.
T1 Port Configuration
You can view the current conÞguration of a WPIM-T1 Ñ or the T1 interface on a
WPIM-T1/DDS Ñ on your CSX201 or CSX400 from the WAN ConÞguration
window (
Figure 4-3 ). You can change the Circuit Id and Line Coding values, and
conÞgure the Fractional Table to represent the use of the timeslots on the T1 line
in relation to the interfaces on your connection.
