## Description

This interface provides access to specific actions that may be performed on available bearers.

## Method Details

### The Connect() method

    Connect ();

Requests activation of a packet data connection with the network using this bearer's properties. Upon successful activation, the modem can send and receive packet data and, depending on the addressing capability of the modem, a connection manager may need to start PPP, perform DHCP, or assign the IP address returned by the modem to the data interface. Upon successful return, the "Ip4Config" and/or "Ip6Config" properties become valid and may contain IP configuration information for the data interface associated with this bearer.

### The Disconnect() method

    Disconnect ();

Disconnect and deactivate this packet data connection.

Any ongoing data session will be terminated and IP addresses become invalid when this method is called.

## Property Details

### The "Interface" property

    Interface  readable   s

The operating system name for the network data interface that provides packet data using this bearer.

Connection managers must configure this interface depending on the IP `"method"` given by the "Ip4Config" or "Ip6Config" properties set by bearer activation.

If MM_BEARER_IP_METHOD_STATIC or MM_BEARER_IP_METHOD_DHCP methods are given, the interface will be an ethernet-style inteface suitable for DHCP or setting static IP configuration on, while if the MM_BEARER_IP_METHOD_PPP method is given, the interface will be a serial TTY which must then have PPP run over it.

### The "Connected" property

    Connected  readable   b

Indicates whether or not the bearer is connected and thus whether packet data communication using this bearer is possible.

### The "Suspended" property

    Suspended  readable   b

In some devices, packet data service will be suspended while the device is handling other communication, like a voice call. If packet data service is suspended (but not deactivated) this property will be `TRUE`.

### The "Ip4Config" property

    Ip4Config  readable   a{sv}

If the bearer was configured for IPv4 addressing, upon activation this property contains the addressing details for assignment to the data interface.

Mandatory items include:

`"method"` | A MMBearerIpMethod, given as an unsigned integer value (signature `"u"`).

If the bearer specifies configuration via PPP or DHCP, only the `"method"` item will be present.

Additional items which are only applicable when using the MM_BEARER_IP_METHOD_STATIC method are:

`"address"` | IP address, given as a string value (signature `"s"`).
`"prefix"` | Numeric CIDR network prefix (ie, 24, 32, etc), give as an unsigned integer value (signature `"u"`).
`"dns1"` | IP address of the first DNS server, given as a string value (signature `"s"`).
`"dns2"` | IP address of the second DNS server, given as a string value (signature `"s"`).
`"dns3"` | IP address of the third DNS server, given as a string value (signature `"s"`).
`"gateway"` | IP address of the default gateway, given as a string value (signature `"s"`).

### The "Ip6Config" property

    Ip6Config  readable   a{sv}

If the bearer was configured for IPv6 addressing, upon activation this property contains the addressing details for assignment to the data interface.

Mandatory items include:

`"method"` | A MMBearerIpMethod, given as an unsigned integer value (signature `"u"`).

If the bearer specifies configuration via PPP or DHCP, only the `"method"` item will be present.

Additional items which are only applicable when using the MM_BEARER_IP_METHOD_STATIC method are:

`"address"` | IP address, given as a string value (signature `"s"`).
`"prefix"` | Numeric CIDR network prefix (ie, 24, 32, etc), give as an unsigned integer value (signature `"u"`).
`"dns1"` | IP address of the first DNS server, given as a string value (signature `"s"`).
`"dns2"` | IP address of the second DNS server, given as a string value (signature `"s"`).
`"dns3"` | IP address of the third DNS server, given as a string value (signature `"s"`).
`"gateway"` | IP address of the default gateway, given as a string value (signature `"s"`).

### The "IpTimeout" property

    IpTimeout  readable   u

Maximum time to wait for a successful IP establishment, when PPP is used.

### The "Properties" property

    Properties  readable   a{sv}

List of properties used when creating the bearer.
