Call Proceeding Tone - Matrix Telecom SIMADO GBR42 System Manual

What's this?
• Some sort of signaling tone is required when a call is terminated on
Mobile/TE/NT Port to inform the user that call is established. It is
done with special Call Proceeding Tone and can be generated by
network or gateway.
• SIMADO GBR42 supports facility of playing feature tone locally to
the caller in case of destination network doesn't give any audible
indication for the progress of call.
• Call Proceeding Tone flag programmed on destination port
determines the feature tone to be played by the SIMADO GBR42
or of the network.
How it Works?
• Call Proceeding Tone flag is of relevance only, if source port is
BRI-NT or DID is enabled on BRI-TE/Mobile port.
For Mobile Port
• When the call is terminated on (routed to) the mobile port, the
originating port can be connected to a tone generator (feature
tone) or to the GSM network.
• If the originating port is connected to the GSM network,
immediately on end of dialing, the caller can listen to the tone
received from the GSM network.
• Whereas if the caller is connected to the feature tone generator,
the caller gets feature tone (which nearly simulates call routing
tone of the network) till 'Call Progress Message' is received
from the GSM network.
• On receipt of first Call Progress Message, the originating port is
connected to the terminating port.
For TE Port
• When the call is terminated on (routed to) the TE port, the
originating port can be connected to a tone generator (feature
tone) or to the ISDN network.
• If the originating port is connected to the ISDN network
immediately on end of dialing, the caller can listen to the tone
received from the ISDN network.
