Wholesale line rental management
 |
Wholesale line rental (in Spain AMLT) is a step beyond carrier preselection and has the advantage of avoiding customer reception of a monthly bill from the incumbent (Telefónica), so it’s seen as a big marketing pro for alternative carriers.
Spanish cable operator, R Cable, has its own access network, but uses indirect access (provided under government regulation) to deliver telephony and Internet to customers out of it network coverage.
AMLT activation, deactivation and modification processes require electronic messaging with Telefónica following a procedure that is complex, prone to formal failures and that may last for one week, more when considering retries and cancellations. Due to the complexity of the process and the messaging, the managing system was developed as an independent module integrated with the order handling system.
- Development and setup of an states machine to handle the messaging and communication with Telefónica. Undocumented behavior was found on Telefónica which had to be supported by the system.
- Design of the integration so it was able to modify orders while in progress , allowing changes on the fly and to avoid having to cancel and create again orders with formal errors.
- Decouple the management of AMLT with the main provisioning process while fulfilling the business requirements beyond the regulated process. This objective was accomplished with a asynchronous and rich communications interface between modules.
