M3SR Series 4100 Common ALE-2G and ALE-3G FF and HF Modem Menus
4.3.7 Common ALE-2G and ALE-3G FF and HF Modem Menus
As already mentioned, after link establishment it is possible to operate in different link modes,
like Fixed Frequency FF, Internal Modem or, in case of ALE-3G, internal protocols HDL and
LDL.
On the other hand, the link modes Fixed Frequency and Internal Modem also called HF Mo-
dem, are available even without ALE, where they have their own operational and configura-
tion menus.
These menus are made available even within the ALE, with the same layout, but some re-
strictions due to the ALE definition.
For Fixed Frequency ALE links, the softkey ‘FF OPERATION’ in ALE Home menu (page
0001) is used to call the ALE FF Operational page with the same softkey layout as described
for Fixed Frequency. Softkey ‘FF CONFIG’ in page 0002 calls the FF Configuration menu.
For HF Modem ALE links, the softkey ‘HF Modem OPERATION’ in ALE Home menu (page
0001) is used to call the ALE FF Operational page with the same softkey layout as described
already for Fixed Frequency. Softkey ‘HF Modem CONFIG’ in page 0002 calls the FF Con-
figuration menu.
