CO Transit - In
This feature automatically re-routes incoming DID/MSN calls from another networked system.
CONDITIONS
• When an outside caller makes a DID call to Station 202, and the DID call request arrives at
the master system, the networking system of Station 202 is not connected to the PSTN
directly. However, it can be connected to the PSTN through another networked system
(master system).
• When a call comes in, the master system checks the received DID call destination. If the
DID destination matches a station within the system, the DID call is routed to the station.
However, if there is no match to the DID destination, the master system searches the
network numbering plan table for possible matches in another networked system. If a
match is found in another networked system, the master system transfers the received
DID call request to the appropriate network networking system.
• When the CO Transit-In DID call rings a Station 202, the caller is then connected when
Station 202 answers.
• There are no timers affiliated with CO Transit-In operation.
• A busy tone sounds to the caller if a networking path is not available during transit.
• When an incoming call is received from the PABX, the call is automatically routed, and a
network CO line is secured according to the DID conversion.
• Incoming calls ring with CLI at the dialed station, and a ring-back tone sounds to the caller.
