By default, auto-answer E&M trunks are answered by the
system with direct inward system access (DISA), and are used
to provide controlled access to Norstar system resources.
When a call comes in on a manual-answer E&M trunk, it alerts
at all telephones with that line appearance.
When a call comes in on an auto-answer E&M trunk that is
configured to answer with DISA, the caller hears stuttered dial
tone. They must enter a six-digit 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
When a call comes in on an auto-answer E&M trunk that is not
configured to answer with DISA, the caller hears system dial
tone. At that point they can then enter one of the following:
• a target line number
• the DISA DN, which will prompt for a COS password
• a line pool access code or a destination code
• a remote feature code from a DTMF telephone
To place an outgoing call, an E&M trunk can be selected by
one of the following:
• pressing a line button on the telephone
• dialing a line pool access code or destination code
• pressing a memory button that has been programmed with
a line pool access code or destination code.
