The following tests cannot be running when a V.54 test is initiated:
H
A Send Pattern Test, Send Remote Line Loopback, Payload Loopback, or
Repeater Loopback on the interface to which the port is assigned
H
DTE Payload Loopback, Send Pattern Test, or Send FT1 Loopback on the
same port
Remote FT1 Data Channel Loopback
The Remote FT1 Data Channel Loopback commands a remote device to go into
Data Channel Loopback on associated port.
"
Procedure
To send a Remote FT1 Data Channel Loopback:
1. Follow this menu selection sequence:
Main Menu
→
Test
→
Sync Data Port Tests
2. Enter the desired slot and port number.
3. Select the code Up or Down in the Send FT1 Loopback field.
4. Highlight Send under Command in the Send Ft1 Loopback row. Then, press
Return to start the test. The code will be sent for up to 10 seconds, or until an
acknowledgement is received from the remote end.
5. View the length of time that the test has been running in the Results column.

Sending and Monitoring Pattern Tests
The pattern tests enable a T1 access unit either to send or monitor a known bit
pattern.
H
These tests generate industry-standard bit patterns that can be used to
determine whether information is being correctly transmitted across a circuit.
H
These industry-standard and user-defined patterns can be sent by the
Network (1 or 2) and DSX-1 interfaces, as well as the Sync Data ports
(toward the Network or DSX-1 interface).
