Table 2 | Fax and Modem Transport Parameters (continued) |
| |
|
|
| |
Fax payload size | Configures the size of the fax payload (fax data) | 20 | |
|
| carried over |
|
|
| value can range between 20 and 48. |
|
|
|
| |
Non standard facilities | Overrides the country code passed by the fax | 65535 | |
country code | machine with the value defined. Setting the value to |
| |
|
| default (65535) results in the gateway passing the |
|
|
| country code values received from the fax machine |
|
|
| to the far end. If the value is not the default, then the |
|
|
| gateway will pass the configured value as the |
|
|
| country code to the far end. It will suppress the |
|
|
| actual country code passed by the fax machine. |
|
|
| Country code can be received by the gateway from |
|
|
| the far end through ISDN. For details about the |
|
|
| nonstandard facilities country code, refer to the |
|
|
| T.35 specification. |
|
|
|
| |
Non standard facilities | Overrides the vendor/provider code passed by the | 65535 | |
vendor code | fax machine with the value defined. Setting the |
| |
|
| value to default (65535) results in the gateway |
|
|
| passing the vendor code values received from the |
|
|
| fax machine to the far end. If the value is not the |
|
|
| default, the gateway passes the configured value as |
|
|
| the vendor code to the far end. It will suppress the |
|
|
| actual vendor code passed by the fax machine. The |
|
|
| vendor code can be received by the gateway from |
|
|
| the far end through ISDN. For details about the |
|
|
| nonstandard facilities vendor code, refer to the T.35 |
|
|
| specification. |
|
|
|
| |
Fax/Modem Packet | Enables packet redundancy support for fax and | Checkbox unchecked | |
Redundancy | modem calls. Packet redundancy support results in |
| |
|
| retransmission of packets in case of problems. |
|
|
| Enabling redundancy can have a negative impact on |
|
|
| performance. |
|
|
|
| |
V.21 Flag Sequence | Specifies the number of V.21 flag sequences that | 4 | |
Detection Count | need to be detected in order to determine that an |
| |
|
| incoming fax tone is valid. Increase this value when |
|
|
| there are line disturbances that require the gateway |
|
|
| to wait for a longer period of time to confirm a fax |
|
|
| call. |
|
|
|
| |
Port Used for Voice | Optimizes the performance of voice calls. If this | Checkbox checked | |
Calls |
| parameter is enabled and the parameters for modem |
|
|
| and fax calls are disabled, the port is configured to |
|
|
| accept only voice calls. Enable this parameter only |
|
|
| if you are certain that a port will handle voice calls |
|
|
| only. |
