Supported Features and Exceptions ADTRAN Routers with CradlePoint CBA750B

Supported Features and Exceptions

The following sections provide information on the feature verification performed and issues discovered

during interoperability verification. The features listed in the

Supported Features section below are the

features verified to work. These are the only features you can expect to function with the configuration

provided in this guide.

Supported Features

The following features were verified during interoperability testing and are supported by the integration:

• Data application - Internet access only

• CradlePoint CBA750B operation in Passthrough mode

• Wireless account activation (initially for a Verizon 4G LTE account)

• CradlePoint CBA750B Force 24 subnet option for IPv4

• Primary WAN operation with ADTRAN routers

• Backup wireless WAN operation with ADTRAN routers

• AOS Firewall and network address translation (NAT) operation for primary and failover WAN

interfaces

• AOS Network Monitor probe operation for keep alive and WAN failover

• ADTRAN Power over Ethernet (PoE) Injector powering for the CBA750B

Exceptions

The following features are not supported by the integration:

• AOS voice over IP (VoIP) operation over the 3G/4G WAN

• CradlePoint CBA750B Router mode operation

The following minor issues were observed during interoperability verification:

• The CradlePoint CBA750B should only be connected to an AOS router Ethernet interface and NOT

to a switchport. The CradlePoint CBA750B temporarily shuts down its Ethernet interface to signal

learning a new public IP address from the wireless service provider. Currently, the AOS switchport

vlan interface will not trigger a new DHCP discovery based on this event.

• Verizon's 4G LTE wireless DHCP service assigns a private (RFC1918) IPv4 address in the form

10.xxx.xxx.xxx to the router. Since this is not a publicly routable IP address, some customer

premises equipment (CPE) applications are not possible, such as hosting, port forwarding, or

remote management access. Customers that require these type of applications will need to obtain a

public static IP address from the wireless service provider.

• The CradlePoint CBA750B should be configured to use the Force 24 subnet option. With the Force

24 option, the CradlePoint DHCP server will always respond with the first host address

(xxx.xxx.xxx.1) in the /24 subnet as the gateway WAN address in response to the AOS router

DHCP request. This avoids addressing issues with the wireless service provider.
