4.7 Connect Port 1+4

Port 1 connected with Port 4.

Teletech TX915: Switch through port (EXCHANGE)

2.8 Port 1+4 Loop to Ground

Loop  Port  1  and  Port  4  and  connected  to  ground  e.g.  for 
resistance symmetrical measurement

2.9 Port 1+4 Loop

Port 1 and Port 4 loop. 

2.10 Port 4 Loop Pulse 3 sec

Port 1 and Port 4 loop pulse for 3 seconds. With it you can 
clearly detect the far end with a TDR even the loop is correct 
terminated on the CO side.

2.11 Connect Port 2+4

Port  4  connected  to  Port  2.  With  it  you  can  switch  e.g.  the 
exchange line on another pair of wires.

2.12 Connect Port 3+4

Port 4 connected to Port 3, Port 1 open

2.13 Connect Port 1+2 and 3+4

Port 1 connected to Port 2 and Port 3 connected to Port 4. This 
configuration allowes to measure two independent loops for 
influence to each other.

Acknowledge  switching 
commands

The switching commands are sent 
from the KE90X with a notification 
so that the user can be sure of the 
correct test setup.
