4.3.2. Remote echo canceller.
It is possible to activate an adaptive remote echo canceller from this menu in G711
communications. This option is independent for C1 and C2 channels.
Access to the menu is through the SETUP section (front panel, no. 9)
- On the main screen, press NO (red) to access the SETUP menu.
- With the cursor arrows, go to the DEFAULTS option and press OK.
- With the cursor arrows, select G.711 and press OK
- With the cursor arrows, select the channel to be configured, and press OK.
- With the cursor arrows, select ECHO CANCELLER option and press OK.
- With the cursor arrows, select ON or OFF.
4.3.3. ISDN Calls at 128 Kbps.
When a call at 128kbps has to be made, it will be necessary to select an audio codification
(MPEG or LD-2), first dial from the first channel (L1), wait until this call is connected and then
dial again from second channel (L2).
It is also necessary to configure, in the DEFAULTS menu, the type of multiplexing to be used
when calls are made at a 128 kbps.
The normal operating mode is J52-type multiplexing; however, for the EAGLE to be compatible
with TELOS (ZEPHYR model) and CCS (CDQ model) audio codecs for 128 kbps modes, it is
necessary to select IMUX multiplexing.
This parameter is in the DEFAULTS section of the menu.
Access to the menu is done through the SETUP section (1) (9).
- On the main screen, press NO (red) to access the SETUP menu.
- With the cursor arrows, scroll to the DEFAULTS option and press OK.
- With the cursor arrows scroll to MPEG LII 128K, and press OK
- With the cursor arrows scroll to IMUX or J52 mode, and press OK to select.
- Press the NO button three times to go back to main screen.
The J.52/IMUX feature should be configured in the same way in both local and remote
audiocodecs when using 128k MPEG encoding algorithms.
