When a call comes in on a DID trunk, the Norstar system
interprets the incoming digits in one of the following ways.
• If the digits map onto a target line, the call is routed to all
telephones with an appearance of that target line.
• If the digits map onto the DISA DN, the caller hears
stuttered dial tone. They must enter a six-digit Class of
Service (COS) password from a DTMF telephone to hear
system dial tone.
They can then enter a:
— target line number
— line pool access code
— remote feature code
• If the digits map onto the Auto DN, the caller hears system
dial tone. They can then enter:
— a target line number
— the DISA DN, which will prompt for a Class of Service
password
— a line pool access code
— a destination code
— a remote feature code from a DTMF telephone
Tips -
Each DID Trunk Cartridge can provide four DID
trunks. Each DID Trunk Cartridge also has four DTMF
receivers dedicated to those trunks. A DTI can provide up to 24
DID trunks.
You cannot configure a DID trunk as the prime line for a
Norstar telephone or a Business Series Terminal.
The capabilities available to a remote caller are determined by
the remote filters and remote package assigned to a line, or by
the set restrictions, line restrictions and remote package
assigned to the Class of Service password.
