The present invention provides a method of managing telecommunications networks through an Operations Support Services (OSS) client and templates. Using an OSS client and various provisioning templates a network manager may interactively provision network services in one or more network devices, in one or more networks, through one or more network management systems. A network manager may interactively establish connections between an OSS client and an NMS server and network device, or the network manager may employ a control template to non-interactively establish these connections. The client/server architecture allows network managers to access multiple different network management servers through multiple OSS clients, and an OSS client may be downloaded from a web accessible server to provide "manage anywhere" flexibility. Moreover, multiple control and provisioning templates may be ordered and sequenced within a batch template to non-interactively complete multiple provisioning tasks on multiple different network devices managed by multiple different network management systems. Through templates and an OSS client, therefore, one or more network management systems may be integrated with a telecommunication network carrier's OSS to simplify the network device provisioning process.
