Deployment
These ATAs provide convenient mechanisms for provisioning, based on two
deployment models:
• Bulk distribution—The service provider acquires these ATAs in bulk quantity
and either preprovisions them in-house or purchases RC units from Cisco.
The devices are then issued to the customers as part of a VoIP service
contract.
• Retail distribution—The customer purchases the ATA from a retail outlet and
requests VoIP service from the service provider. The service provider must
then support the secure remote configuration of the device.
Bulk Distribution
In this model, the service provider issues these ATAs to its customers as part of a
VoIP service contract. The devices are either RC units or preprovisioned in-house.
RC units are preprovisioned by Cisco to resynchronize with a Cisco server that
downloads the device profile and firmware updates.
A service provider can preprovision these ATAs with the desired parameters,
including the parameters that control resynchronization, through various methods:
in-house by using DHCP and TFTP; remotely by using TFTP, HTTP, or HTTPS; or a
combination of in-house and remote provisioning.
RC Unit Deployment
RC units eliminate in-house preprovisioning of and reduce the need for the service
provider to physically handle the devices prior to shipping them to end customers.
This approach also discourages the use of these ATAs with an inappropriate
service provider.
A RC unit is preprovisioned by Cisco with the connection information for the
provisioning servers. These servers are maintained by Cisco Systems, Inc. for the
service provider that purchased the units. The MAC address of each RC unit is
associated with a customizable profile on the Cisco provisioning servers. When
the RC unit is connected to the broadband link, it contacts the Cisco provisioning
server and downloads its customized profile.
