USB Modem Terms
Before configuring USB modems and their supporting dialer interfaces, become familiar with the terms defined in Table 99.
Table 99: USB Modem Terminology
Term | Definition |
|---|---|
caller ID | Telephone number of the caller on the remote end of a backup USB modem connection, used to dial in and also to identify the caller. Multiple caller IDs can be configured on a dialer interface. During dial-in, the device matches the incoming call's caller ID against the caller IDs configured on its dialer interfaces. Each dialer interface accepts calls from only callers whose caller IDs are configured on it. |
dial backup | Feature that reestablishes network connectivity through one or more backup dialer interfaces after a primary interface fails. When the primary interface is reestablished, the USB modem backup is disconnected. |
dialer interface | Logical interface for configuring dialing properties and the control interface for a backup USB modem connection. |
dialer profile | Set of characteristics configured for the USB modem dialer interface. Dialer profiles allow the configuration of physical interfaces to be separated from the logical configuration of dialer interfaces required for USB modem connectivity. This feature also allows physical and logical interfaces to be bound together dynamically on a per-connection basis. |
dial-in | Feature that enables devices to receive calls from the remote end of a backup USB modem connection. The remote end of the USB modem call might be a service provider, a corporate central location, or a customer premises equipment (CPE) branch office. All incoming calls can be verified against caller IDs configured on the device's dialer interface. |
