Messaging - Call Me Back
A set user calling a busy or unanswered set can leave a message for the party to return the
call. The message waiting indication can be
• A flashing lamp on the set at 0.5 seconds on, 3.5 seconds off (if equipped)
• An indication on the set’s display (if equipped)>
• Ringing at the set with a distinctive ringing pattern.
The Message Waiting indication continues until the set user reads the message. Messages
can be read when the set is idle or during a call. On SUPERSET display telephones, the display
shows the time of the call, and the caller’s extension number and name (if programmed).
Optionally, the system can be programmed to record each occurrence of Message Waiting on
the system printer when the message is sent from the Console, the Front Desk Terminal or PMS.
Meter Pulse Collection
Meter Pulses are often used to calculate the cost of outgoing trunk calls, thus allowing the call
to be charged back to the originator. The system can be set up to detect and collect certain
types of Meter Pulses sent to a trunk circuit during outgoing calls. These are then recorded in
the trunk’s SMDR reports. Types of Meter Pulses which can be detected by the system without
additional hardware include
• Tip-Ring reversals
• XT lead signaling (Analog CO Trunk)
• M&MM lead signaling (Digital LS/GS Trunk).
Other types of Meter Pulses common in the telephone industry include 50 Hz, 12 kHz, and 16
kHz type pulses. Detection of these types requires the addition of an external interface which
converts these pulses to a ground signal which is then applied to the XT Lead for the Analog
CO Trunks, or to the M or MM lead for the Digital LS/GS trunks. (For Digital LS/GS trunks, -48
Vdc must be applied to the other lead so that when the ground is applied to the M or MM lead,
current flows through the circuit and gets detected as a pulse.)
This feature is associated with the Message Registration feature. See Property Management
System for additional information.
MILINK Data Module
The MILINK data module is a limited distance, asynchronous, digital dataset that converts the
data signals of RS-232 serial devices to high-speed digital signals. It allows an RS-232 device,
such as a computer or display terminal, to be connected to the system through a SUPERSET
410, SUPERSET 420, or SUPERSET 430 telephone. The 2-pair cable that connects the
SUPERSET telephone to the switch carries both voice and data signals, allowing a user to use
the RS-232 device and the SUPERSET telephone simultaneously.
