AirCard 555 Network Card User Guide
Table 7-4: General Tab Options
Field | Description |
|
|
System Select | This field allows you to prevent the AirCard |
| from roaming or limit roaming to specific |
| channels. (The term “roaming” is explained |
| on page 18.) |
| CDMA networks use designated radio |
| frequency channels. In every cellular |
| market, the channels are divided into two |
| sets: the A side channels and the B side |
| channels. CDMA network carriers (or |
| service providers) are assigned either the A |
| side or the B side channels in each market |
| by the regulatory agencies that oversee |
| radio transmissions. |
| The options in this field are: |
| • Home |
| from roaming |
| • |
| roam on networks of “preferred” |
| service providers. |
| • Automatic |
| roam on networks of “preferred” |
| service providers as well as “non- |
| preferred” A side service providers. |
| • Automatic |
| roam on networks of “preferred” |
| service providers as well as “non- |
| preferred” B side service providers. |
| Based on the SID (System Identifier) |
| assigned to your account during activation |
| (see page 19), the default in this field is |
| either Automatic A or Automatic B. It is |
| recommended that you leave the default, |
| unless you are advised to change this field |
| by technical support. |
