■ Property Management System (PMS)
PMS products accept only extensions of 5 digits or shorter. Therefore, a
customer using PMS cannot use 6/7-digit extensions.
■ Uniform Dial Plan
The following limitations apply to a DCS environment:
— Extensions that differ in length from the UDP do not distribute to
other switches.
— You can use only a single length in your UDP.
■ Single-Digit Dialing
■ A prefixed extension is still made up of a prefix and an extension of
up to five digits.
■ Mixed station numbering extensions can have 1 - 7 digits.
Distinctive ringing
Distinctive Ringing provides several ringing cycles to help telephone users and
attendants distinguish between incoming call types. Administer Distinctive
Audible Alerting on Feature-Related System Parameters for internal, external,
priority, and attendant originated calls. If the phone is a single-line analog, you
have to set this on the Station screen for each user.
Detailed description
You can administer system-wide distinctive-ringing cycles for the three basic call
types. Most installations use 1-burst for internal calls, 2-burst for external calls,
and 3-burst for priority calls. There are also non-administrable ringing signals for
Automatic and Dial Intercom calls, Manual Signaling, and Redirect Notification.
Normally if an internal phone user transfers an external call, the call rings as
internal. You can set a feature parameter (Update Transferred Ringing Pattern) to
make the call ring as an external call.
