the Configuration menu.
The datacom settings are specified.
Configuring the frame load
settings
You can configure frame characteristics such as the traffic load type and rate,
frame length, and payload data. The following procedure describes how to
specify these characteristics.
To configure frame load settings
1 If you haven’t already done so, launch the Frame Relay application (see
“Launching the Frame Relay application” on page 64).
2 On the Configuration menu, select FR Load Settings, and then specify
the following settings:
Data Rate Determine the data rate of the device you will be
connecting to, between 50 and 10,000,000Hz. In
asynchronous mode, you must configure the
E1/
Datacom Tester
to use the same rate.
DTE Rx Timing The receive timing for data applications.
DCE Rx Timing The receive timing for data applications.
Tx Timing The transmit timing for the data applications.
Rx Input Receive input termination settings, in Ohms, for the
balanced Data interfaces.
Clk Loss Thres. The number of milliseconds, between 0 and 1000,
without transitions on the clock signal lead needed
to declare clock loss.
Data Loss Enable Enabling (or disabling) data loss detection criteria
affects Rx data loss counts and alarms. Enabling the
criteria causes the
E1/Datacom Tester to register
data loss when no data transitions have occurred for
63 clock transitions in synchronous timing modes.
Setting Parameter
Setting Parameters
Load Type Select a traffic load type:
– None: No traffic load is generated.
– Fixed: Causes the E1/Datacom Tester to transmit
frames constantly at a specified rate.
– Burst: Causes the
E1/Datacom Tester to transmit
a burst of traffic followed by a specified period of no
frame transmissions (burst idle time).
– Ping: Causes the
E1/Datacom Tester to transmit
one ping per second.
Load Rate
(Fixed loads only)
Enter a value, from 1 to 10000 kbps, for the data load
rate.
Note: It is possible to enter a load rate that exceeds the
data rate for the interface.
