How to Run the Console Link Test for 3745 Models 130, 150, 160, and
170
This function is available for 3745 Models 130,
150, 160, and 170 only.
This function tests the customer's console ports
with wrap plugs which may be installed at the end
of the cable. They are attached to either the local
console, the remote console modem, or the RSF
link modem. The wrap plugs can also be installed
at the connectors for these cables in the 3745 (not
possible with the 3727 console cable).
This test can be run without stopping the cus-
tomers application.
