14. Set DIP switches SW5-1 through SW5-7 (Channel 1), and DIP switches SW9-1 through SW9-7
(Channel 2) to the nominal receive level. The valid range is +10dBm to –31.5dBm. See Table 5
for reference.
For example if the nominal incoming PCM data is 0dBm0 and the desired output
level is +7dBm then the switches should be set for +7dBm. This will provide a
nominal +7dBm0 at the receive TLP, and leaves approximately 3dB of headroom.
In this case the peak receive TLP would be +10dBm. The factory default is +7dBm
receive (analog out).
DIP switches SW5-1 to SW5-7 are labeled as follows:
SW5-1 +/-
SW5-2 16
SW5-3 8
SW5-4 4
SW5-5 2
SW5-6 1
SW5-7 0.5
The switch settings are cumulative. For example, to set the nominal receive level to
+7dBm, set the switches as follows:
Section Value Setting Set Value
SW5-1 +/- OFF +
SW5-2 16 OFF 0
SW5-3 8 OFF 0
SW5-4 4 ON 4
SW5-5 2 ON 2
SW5-6 1 ON 1
SW5-7 0.5 OFF 0
_______
Nominal receive level setting = +7dBm
15. Set the position of SW4-8 to enable or disable Channel 1 signaling.
Place SW4-8 to the ON position to enable Channel 1 signaling.
Place SW4-8 to the OFF position to disable Channel 1 signaling.
Set the position of SW8-8 to enable or disable Channel 2 signaling.
Place SW8-8 to the ON position to enable Channel 2 signaling.
Place SW8-8 to the OFF position to disable Channel 2 signaling.
16. Set the position of SW7-8 and SW7-9 to enable or disable FXS/FXO modes for Channel 1 in accordance
with Table 1 on page 18 as applicable.
Set the position of SW11-8 and SW11-9 to enable or disable FXS/FXO modes for Channel 2 in
accordance with Table 1 on page 18 as applicable.
