Send 1:4 Test (or Alternate)
The
1:4
code is the standard loop up remote code. It is typically
used to put the remote system into loopback. You can determine if
the failure is an intermittent or a hard failure by continuously sending
the
1:4
code, and monitoring the network status to see if the pattern is
being received.
The selections are available on the full bandwidth and on Data Port
1
.
The full bandwidth code puts the remote system into full network
loopback. When used on Data Port
1
, the code puts the
corresponding remote port into Loop Payload .
Send
1:2 Test
The
1:2
code is the standard loop down remote code. Use it when the
Loop Down Remote test fails to terminate the remote loopback. You
can determine if the failure is an intermittent or hard failure by
continuously sending the
1:2
and monitoring the network status to
see if the pattern is being received.
The selections are available on the full bandwidth and on Data Port
1
.
The full bandwidth code takes the remote system out of full network
loopback. When used on Data Port
1,
the code takes the
corresponding remote port out of Loop Payload .
User 1/User 2 Patterns Test
These two user programmable (up to
24
characters) patterns enable
you to generate a test pattern rather than using pre-programmed
patterns or live trafÞc.
Lamp Test
Use this test to verify the
LED
s. During the test, all
LED
s on the front
panel light.
Running Tests from the Front Panel
You can also run the tests from the front panel. Refer to ÒUsing the
TEST MenuÓ in Chapter 5 for further information.
