EX7100 Technical Manual – Monitoring and Diagnostics

Note 1: If the remote terminal is unable to be contacted, due to a faulty link or if another

user is accessing the terminal, a message will be displayed:

Note 2: When accessing a remote menu there will be a short delay between pressing a

key and the menu changing, due to the limited data speed of the engineering

channel.

4.3.2 Closing the Test Link

When you have finished the remote interrogation, you should close down the test link,

even if the link was already established (with data or telephone traffic). If a test link is not

closed down manually it will be shut down automatically after 10 minutes.

1) Press the ‘Escape’ key until the menu

display is as shown. Use the up and down

arrow keys to make sure the →

→→

→ is next to

End Remote Tests and then press ‘Enter’.

2) If there is no telephone or data traffic using the system, the EX7100 will close down the link

(both the Tx and Rx LED’s will go out).

If there is telephone or data traffic using the system, the EX7100 will close down the test

link, but the link will continue to operate (both the Tx and Rx LED’s will remain on).

3) Press ‘Escape’ until the display returns to idle.

Important Note:

While a terminal is being remotely accessed, it will not be able to be accessed locally. The

remote terminal display will read:

4.3.3 Changing Operating Frequencies Remotely

As previously discussed in Section 3.4.1, it is possible to configure an EX7100 terminal

remotely, with the process being identical to configuring a local terminal.

There is however, a slight change in process when changing the Operating Frequencies

or Channel Increment remotely, or locally with a link established.

Consider a link operating on Tx 450.000 MHz and Rx 455.000 MHz, with a requirement to

change this to Tx 450.050 MHz and Rx 455.050 MHz.

If we followed the procedure outlined in Section 3.4.1 for an idle terminal, the local

terminal’s frequencies would change but there would be no means of setting up a link with

the remote terminal, as the new local frequencies would no longer match the remote

terminal’s frequencies.
