■QSIG networks — Providing a 6- to 7-digit private-network dialing plan
makes it easier to convert a large DCS network to QSIG. You can
implement QSIG networks with all the QSIG Supplementary Services
installed in your network. It also makes it easier to integrate DEFINITY
ECS into existing networks composed of non-Lucent systems.
■3-digit Uniform Dial Plan — This feature provides a 3-digit dialing scheme
similar to uniform dial plan.
NOTE:
DCS will not work using a 3-digit dialing plan. 3-digit dialing
requires QSIG for feature transparency.
If the caller dials enough digits to match the aar or ars field entry, the dialed digits
are analyzed as though the AAR or ARS FAC had been dialed.
Displays
On display phones, the internal extension dialed appears instead of the shortcut
number. Malicious Call Trace (MCT) displays the short, internal extension of the
internal caller. Refer to ‘‘Malicious Call Trace’’ on page 1421 for more
information. On display phones with directory service, the CALL DISPLAY button
cannot be used in networks where 6 or more digits are required for internal calls.
Refer to ‘‘Integrated Directory’’ on page 1501 for more information.
Emergency numbers
Shortcut dialing allows users to make emergency calls (for example, 911 in the
U.S. and 112 in Europe) without first dialing an access code.When this is set up
correctly, other 4- or 5-digit extensions tha t begi n with the s ame leading digit (9 i n
the U.S. and 1 in Europe) cannot be dialed.
Interactions
■Abbreviated Dialing
You can store AAR/ARS shortcut numbers on Abbreviated Dial buttons.
■Attendant direct extension selection with busy lamp
On third-party call forwarding, attendants must dial the full extension of
the phone to be forwarded, and may use the Direct Extension Selection
(DXS) button and the shortcut dialing number for the destination phone.
Attendants cannot use DXS modules in a network where users are required
to dial 6 or more digits for internal calls.
