3.2 Cornet

Cornet is a digital virtual port for the StarPoint key phones with proprietary signalling (UPN interface). The Stack tab provides limited configuration capacities only. The parameters are divided into logical sections according to their respective functions. For the StarPoint configuration parameters refer to the Softphone subtab of the Properties tab.

 

Virtual port status

The upper menu field displays information on the stack type and its current status including information on the L1 and L2 states, increased bit error rate or nonsynchronous L1.

 

Digital interface parameters

  • Interface type – the parameter cannot be configured. It only shows the type of interface.
  • Interface mode – this parameter is set to NT and cannot be reconfigured. Thus, cross-connecting lines cannot be made using these ports.
  • Bus mode – this parameter is always set to PTP and cannot be reconfigured. This port is used for one terminal only.
  • Enabled channels – enable selected interface channels. If none is enabled, the interface cannot be used and behaves as if it was busy.
  • Keep L1 active – make the PBX keep the interface active automatically.
  • Inactive L1 as error – activate a caution about the first layer being inactive. This is indicated by a red exclamation mark on the port in the Hardware – Boards menu and a red text in the upper stack status field.
  • Set BER – select BER as error to enable acceptable BER range parameters. If the BER rate gets over the BER error level, a red exclamation mark appears on the port in the Hardware – Boards menu and a red text is displayed in the port status field. This error status gets changed after the BER value falls below the BER OK level. The interval between these two values represents hysteresis. The BER values are entered in an exponential format (e.g. 3e–5 means 3 errors in 100,000 bits).

Master terminal

  • Type – shows the type of the StarPoint terminal connected.
  • Firmware – shows the current firmware version of the terminal connected.
  • Extenders – shows information on the active extenders of the terminal connected.

Slave terminal

  • Type – shows the type of the StarPoint terminal connected.
  • Firmware – shows the current firmware version of the terminal connected.
  • Extenders – shows information on the active extenders of the terminal connected.

Digital interface diagnostic

  • Line state – the parameter cannot be configured. It only shows the state of the first interface layer.
  • Number of SLIPs per minute – shows the count of SLIPs. A SLIP is caused by different clocks on the PBX and the terminal. This value is updated every 6 seconds and represents a weighted average per minute.
  • BER per second – the Bit Error Rate shows the count of incorrectly transferred bits on the interface during transmission. The value is updated every 6 seconds and represents a weighted average per minute.
