Send FT1 Up/Down Sequences

5-12
The local DSU/CSU can send an ANSI T1.403 (Annex B) Up or Down sequence
to request the start or stop of a Data Channel Loopback on a remote DSU/CSU.
The DSU/CSU can send:
In-band ANSI T1.403 (Annex B) Up (activation) code to request the start of a
Data Channel Loopback at the remote DSU/CSUs or
In-band ANSI T1.403 (Annex B) Down (deactivation) code to request
termination of a Remote Data Channel Loopback at the remote DSU/CSU.
Procedure
To send a FT1 Up or Down sequence to a remote unit:
1. Position the cursor at the Up or Down selection next to Send FT1 Loopback
on the Data Port Tests screen.
2. Press the space bar to select the desired code (Up or Down).
3. Position the cursor at the Start command next to Send FT1 Loopback on the
Data Port Tests screen.
4. Press Enter.
5. The Start command is changed to Sending. The Up or Down sequence
transmission stops automatically after 10 seconds. You cannot stop the
sequence manually.
The Send FT1 Up/Down test cannot be started when any loopback or Send
Pattern test is active on the network interface.
