Operation

∙ASMi-450 Unit Configured as Remote Unit (NTU). The ASMi-450 unit configured as remote unit always locks its internal system timing to the incoming HDSL signal, which is received from the ASMi-450 unit configured as central unit. The receive path of the ASMi-450 uses the recovered timing to generate the data stream supplied to the equipment connected to the remote user's port. Therefore, the receive path of the remote ASMi-450 transparently transfers the timing from the HDSL line to the remote user's equipment.

The ASMi-450 system is designed for unattended operation. The configuration of the ASMi-450, that is, a complete collection of operating parameters, is determined by a data base stored in non-volatile memory.

Local Control

The ASMi-450 can be controlled by means of a simple menu, operated by push- buttons located on the front panel. During set-up, an LCD display guides the operator in the execution of the desired operations. The display provides information concerning the current system configuration and operating mode, and the available values of each programmable parameter. In case of operator errors, the ASMi-450 displays a message that explains the error and helps the operator take the correct action.

Remote Management

In addition to front panel control, the ASMi-450 supports management from a remote location. The remote management capabilities can be used to perform the following activities:

∙ASMi-450 configuration.

∙Reading of ASMi-450 status.

∙ASMi-450 testing.

∙Display of alarm status and history.
