FT 100S
DTE Port Remote Loopback
Figure 4-6 shows DTE port in Remote Loopback. The local FT 100S
puts the DTE port on the remote FT 100S in remote terminal loopback
by sending a (5 bit) repeating pattern (11110) transmitted inband for at
least 5 seconds.
The loop pattern continues until the local FT 100S recognizes that the
remote FT 100S is looped. As an option, the local DTE signal may be
replaced by an internally generated test pattern.
The test pattern is transmitted to the remote FT 100S and monitored by
the local FT 100S for errors indicated by an LCD message.
The TM LED lights to indicate a test in progress. On the remote FT
100S, the TM LED blinks to indicate a remotely activated test in
progress. Other LEDs function normally.
