NIC (V.35/RS449/RS530/X21) 

To set G.703 choose YES for default - G.703. 
To set NIC choose No for default - G.703. 
Once the interface has been chosen, the configuration menu can be accessed by selecting the NIC icon. 

In order to use G.703, it is necessary to have a licence (see section on licensing for more information). 
In this menu you can: 

•  Choose either the E1 or T1 protocol 

If the system has already been configured to support a PRI interface (either Euro or National), the E1/T1 
option is not available and the system is automatically set to the appropriate mode: 

 

Euro Primary Access   G.703 E1; 

 

National Primary Access   G.703 T1. 

•  Choose the Rate; 

•  Set the Network Speed(64K or 56K); 

•  Enable/Disable automatic calls 

To make an automatic call: 

1.  Enter Audio-Video call page 
2.  Select NIC in “Type of call” drop-down menu 
3.  Wait for few seconds, and the System will automatically start the call 

 

•  Enable/Disable CRC4 (E1 only); 

•  Enable/Disable the “Enabled Alarms” option; 

•  Configure the System to be either “Master” or “Slave” in calls.  

•  “G.703 advanced” settings (T1 only).  

Choosing the modality T1 is possible to select the icon "Advanced" for select the appropriate cable length. 

 

If the system is configured with PRI lines, Euro or National, the System automatically selects the net in the following way: 
Primary Rate Euro Access → G.703 E1; 
Primary Rate National Access → G.703 T1. 

This section allows you to customize the NIC interface. The network type (X.21, V.35, RS449, RS530) is automatically 
recognised by the system. 
Available options: 

•  Select the maximum rate from the drop-down menu 

•  Select Automatic Call to make the call if network alarms are not present

switched when combined with RS366) 

•  Select TERMINATION to insert terminations on the interface signals  

•  Select CLOCK RX=TX for identical bit rates in transmission and reception 

 
Select ADVANCED in order to display the following advanced settings:  

ON indicates that the signal is managed (OFF indicates that the signal is not managed) 

For all signals: ON indicates normal management of the signal, while OFF sets the value of the signal to “active.”  
Selecting ON/OFF/ON in the DTR box activates the “Resync pulse”.  
Selecting RING in the CD box indicates the signal is used for announcing an incoming call.
