Note
For the best results, increase or decrease both the local output level and remote input level settings by a small amount to change the volume level heard at the local voice/fax channel.
The default settings per configuration are as follows: | ||||
| Local | Remote | ||
Configuration | IL | OL | IL | OL |
FXS to FXO | 6 | 9 | 5 | 2 |
FXS to FXS | 3 | 12 | 3 | 12 |

Voice/Fax Channel | The Voice/Fax Channel Silence Suppression command keeps |
| ||
Silence Suppression | moments of silence from using up bandwidth on the composite | link. Typically, a voice | ||
conversation is 50 to 60% silence. Silence | V(1/2)SS | suppression is helpful when using a slow composite link | ||
speed | such as 19,200 bps. The higher the command level (e.g., | V1SS2), the | ||
greater the silence suppression. The range of the | command is from 0 to 2. When silence suppression is set to | |||
zero, | all sound passes through the link, even silence. Silence | suppression | ||
is active when there is no activity on the voice/fax | channel. Increasing the setting | increases the volume | ||
necessary | for sound to be sent over the link. |
| ||
Voice/Fax Channel | The Voice/Fax Channel Local Interface command configures |
| ||
Local Interface | the local voice/fax channel interface. The V1LIFXO command | sets voice/fax channel | ||
1 on the local MultiMux for an FXO | V(1/2)LI | connection. When the local MultiMux is configured for FXO, | ||
the | remote site has to be configured for an FXS interface. When the | l o c a l | ||
MultiMux is configured for an E&M interface, the E&M type | has to be determined, whether dial or wink is going | |||
to be used, | and whether the connection is | c o n f i g u r e | ||
local voice/fax channel 1 for E&M type 1 which is | very common in the U.S., | |||
wire | connection, the command would be V1LIE&M1W2. The Local | C h a n n e l | ||
Interface command are as follows: |
|
|
| |
| ATV(1/2)LIFXO | FXO Interface | Connects to station |
|
| side of PBX. |
|
|
|
| ATV(1/2)LIFXSG | FXS w/Ground | Connects a single |
|
Start Line | telephone/fax with a |
|
| ground start line to the |
|
|
| mux. |
