This read-write integer identifies which of up to 16 predefined connection templates (parameter presets) is associated with this connection, with the special value 17 explicitly meaning no template is applied and the connection's parameters were set individually instead. Admins use connection templates to quickly apply a consistent, pre-defined set of traffic parameters to multiple connections rather than configuring each parameter manually every time. For example, an admin provisioning many similar VBR connections for a given service tier would set ausmConnTemplateId to the template number matching that tier rather than manually setting PCR, SCR, and MBS on each connection.
