4. Check that you have defined a Received number for every
target line in your system.
5. Make sure that the published telephone numbers for your
network are correct.
Possible problem
The Norstar system did not receive some or all of the incoming
digits.
Solution
1. Check that the system hardware is receiving signals
properly.
2. Verify that the switch is sending the correct number of
digits for the Received number length defined in your
system.
3. If the switch at the far end is sending pulse signals, make
sure they are being sent at the proper rate.
Pulse digits must be 300 ms or more apart for Norstar to
receive them.
Possible problem
If remote callers are having difficulty getting through from the
public network, there may be a problem with your DID Trunk
Cartridge.
Solution
1. Connect a single-line DTMF telephone to a DID trunk
input on the DID Trunk Cartridge.
2. Use the single-line telephone to enter a Received number
that has been programmed for a target line in your system.
