Message Waiting
Description
Message waiting allows station users to leave notification that an attempt at contact has been made. On
G1-824 digital telephone stations, the [MSG] pushbutton will flash to indicate a message is waiting on the
telephone set. On G1-824 digital telephone stations equipped with LCD displays, the notified party can
read the name of the user(s) that has left the message(s) on the telephone.
Single Line Telephones can be programmed to periodically ring (approximately every 5 minutes) when a
message is left. If the called station answers during the ringing cycle (ringing cycle is approximately 30
seconds), it will either call the station that left the message or be routed to the Voice Service Unit, to
inform the called party of the message waiting. The VSU will not store a message, it will only indicate to
the station user that there is a message waiting. This is dependent upon system programming, Mode 05-
04-08.
Single Line Telephones also will hear interrupted dial tone whenever the handset is lifted and a message
is waiting. This consists of 250 milliseconds of dial tone and 250 milliseconds of silence, repeated over
and over. If not desired this option can be eliminated through programming of Mode 05-03-07 (SLT Dial
Tone Options).
Conditions
A maximum of five messages can be stored on a station. The tones available for single line telephone are
programmable in accordance with Mode 05-03-07.

Single Line Telephone Message waiting type, Mode 05-04-08 determines the method used to notify a
single line telephone user of the type of message waiting notification to be used. The two types offer the
options of ringing directly back to that station that left the message. Valid parameters for this are:
SLT MSG Waiting Type, (Mode 05-04-08)
0= No Message Waiting
1= Ring
2= Voice Message
3= 250 ms. Ring burst
Mode 46-[STN]-02, Message Waiting Level, determines the hierarchy of stations. A station may only
activate message waiting on a station of the same or lower message waiting hierarchy. The valid settings
are 0-9, where 0 indicates a station that is unable to leave a message. Level 9 provides the capability to
leave a message to any station within the system.
