DSL CPE Network Management

The local authorities of Bradford and Stoke in the United Kingdom carried out a programme to provide subsidised broadband access to about 15000 rural residents. As part of a local-loop unbundling (LLU) project, Travelping was chosen to plan and develop of the broadband network architecture.

BRAS and TPOSS

For the network implementation, Travelping delivered several Session Control Gateways (SCG) which were used as Broadband Remote Access Servers (BRAS) to control the broadband subscriber sessions.

The Travelping Open Subscriber Server (TPOSS) was deployed to manage the user and device policies. Given the budget and time constrains as well as to reduce operational costs a zero-touch installation mechanism for the Customer Premises Equipment (CPE) was required.

Smart Integration

Travelping enhanced the system further with line- and device-based authentication and employed smart integration of the existing Multi Service Access Nodes (MSANs) and aggregation network equipment to avoid the management and handling of subscriber-specific credentials.

All CPEs were equipped with a TPLINO-based firmware stack to establish the DHCP-based Internet connection and provide services in the customer LAN. The devices were automatically monitored and updated through the Travelping TR-069 CPE management system.
