MUSIC-ON-BOLD 
7.01 The system may be 
equipped with an optional music source 
for calls on hold and calls waiting. 
This feature not only makes 
the wait as pleasant as possible, 
party that they are still connected. but it assures the holding 
7.02 Music-On-Hold is enabled on the MISC PCB. 
The music.source 
is selected from an external source or from a choice of two syn- 
thesized melodies. 
8. 
CALL PRIVACY 
8.01 The call privacy feature restricts access to a call by all 
other station users. 
This applies to intercom and outside calls. 
8.02 When a private intercom path is 
selected by lifting the 
handset and pressing the DSS key, 
intercom path. no other station may seize the. 
However, 
a handsfree intercom call may be in- 
terrupted by the Meet Me feature, 
which accesses the lowest- 
numbered intercom path. 
8.03 When a C.O. 
line is selected by pressing one of the eight 
line keys, no other station can seize that line. 
Control of the 
line may be transferred to another station through a conference 
or a call transfer. I. .

TOLL RESTRICTION 
9.01. 
As a cost-controlling feature, 
the 824 system has the capa- 
bility of restricting specific stations from accessing C.O. lines 
or from making toll calls. 
These restrictions are programmed by 
service personnel. 
To cover these topics, this section contains 
the following:

A. TOLL RESTRICTION CLASSES 
9.02 The system has 
four toll restriction classes, which are 
assigned by Maintenance Panel Program 30. They are: 
A. 
B. 
C. 
D. Class A: 
Completely unrestricted, 
but may be restricted 
from dialing local information during programming. 
Class B: 
Calls are allowed which begin with 800, 900, or 
911. Long Distance Information (LDI) calls, SCC calls, 
local calls, and calls within the allowed area codes are 
also permitted. May be restricted from dialing local 
information. 
Class C: Calls beginning with 800 or 911, LDI, SCC and 
local calls, as well as calls within the local area code 
are allowed. May be restricted from dialing local infor- 
mation. _ 1.. 
Class D: Only local calls and calls beginning with 800 
or 911 are permitted. May be allowed to dial local in- 
formation. 
9.03 Other toll-restriction features may also be programmed, 
using the Toll Restriction (8) program on the terminal. These 
include WATS line access, SCC access, local information calls, 
and the allowed area codes list. Each is discussed below. 
B. WATS LINE ACCESS 
9.04 A station may be programmed to have access to an unre- 
stricted line which is used to place calls that may otherwise be 
denied. This line does not need to be an actual WATS line. It 
may be a local C.O. line, FX line, PBX line, etc., that the user  
wishes to exclude from the toll restriction function. 
C. AIUHED AREA CODES LIST 
9.05 A list of up to 30 allowed area codes may be developed and 
applied to Toll Class B stations. The system will allow Class B 
stations to place calls to these area codes. If a toll/long dis- 
tance call is denied, the station user hears a busy signal. 
D. SPECIALIZED COMMON CARRIER (SCC) ACCESS 
9.06 Any station, except those in Toll Class D, may have access 
to an SCC number. This number is used to place toll/long dis- 
tance calls that are otherwise denied for the station.

E. LOCAL INFORMATION CALLS 
9.07 Any of the four toll restriction classes may be programmed 
to allow local information calls (411 or 1411). 
-.lO. DIRECT RING-IN LINES 
10.01 A C.O. line may be programmed to flash and/or ring in 
directly on-only-one keyset, creating a private line. 
Other 
stations may be restricted from this line during programming. 
11. VARIABLE TIME-OUT CAPABILITIES 
11.01 This feature provides varying time parameters for the 824 
system. Figure 8-2 below lists the timers available. 
Timers are 
either preset or programmable. 
Where applicable, variable values 
are given.

flash rates of the LEDIs have distinct 
meanings as shown in 
Figure 8-4 on the next page. The flash rates are described below 
in Interruptions Per Minute (IPM): 
a. STEADY - No flashing. 
b. FAST - Flashes 120 IPM or two times per second. 
Flutters when some features are used. 
c. MEDIUM - Flashes 
60 IPM or 
one time 
per second. 
Flutters when some features are used. 
d. SLOW - Flashes 30 IPM or once every two seconds. 
e. DELAYED - Flashes 15 IPM or once every four seconds.

Immediate Ringing 
2.08 Immediate ringing is provided for all calls to. a station. 
A called station receives ringing immediately after the station 
circuit is tested and found to be idle. 
D. DISPLAY KEYSETS 
2.09 Display keysets (824D) may be used on the system. 
These 
keysets are equipped with a liquid crystal display (LCD) for 
displaying call information and status messages. 
When the keyset . 
is idle, the date and time are shown. 
enced throughout this section. Other messages are refer- 
E. VOLUME AND RING TONE CONTROL 
2.10 The volume for voice communication and signal tones heard 
through the keyset speaker are adjustable. Each keyset is 
equipped with a volume control thumbwheel on the right-hand side 
of the instrument. The handset (receiver) volume control slide 
switch affects the voice signals received through the handset. 
_, 
I?. CALL NUMBER BUFFERING 
2.11 Digits dialed are buffered by the CPU, 
preventing the user 
from dialing too fast -for processing. 
G. DIRECT INCOMING LINE FLEXIBILITY 
2.12 Direct incoming line flexibility is a feature that allows 
the user to assign any combination of the eight 
lines to ring in and/or flash on specific stations. incoming C.O. 
for ring-in are programmed, Assignments 
using Maintenance Panel Program 32. 
2.13 Since the 824 system is a square key system, a C.O. line 
must appear as the same physical line key on all keysets, even if 
all keysets -cannot access it. 
H. C.O. LINE RESTRICTIONS 
2.14 A station may be restricted from accessing 
any of the eight 
C.O. lines for outgoing calls, 
using Maintenance Panel Program 
31. An attempt to use a restricted line produces a busy signal. 
However, calls on restricted lines may be received from and 
transferred to other stations.

3. INTERCOM FEATURES 
3.01 The intercom features presented in this section are as 
follows: 
A. Flexible Intercom Numbering 
B. Voice Announcing 
C.- Handsfree Answering 
D. Station-to-Station Calling 
E. 
Intercom Camp-On and Call Waiting 
A.- FLEXIBLE INTERCOM NUMBERING 
3.02 All stations are accessed with one keystroke, 
by pressing a 
DSS key. Intercom number assignments are flexible and can be 
changed through the data base by service personnel. Duplicate 
intercom number assignments are not allowed. 
B. VOICE ANNOUNCING 
3.03 An internal speaker in the 824 keyset is initially enabled 
to allow voice announcing on intercom calls to idle stations. 
The called party will hear 
the announcement and may respond 
handsfree. This feature may be disabled with Maintenance Panel 
Program 22. 
C. 
HANDSFREE ANSWERING 
3.04 If your station is programmed for handsfree answering 
(Maintenance Panel Program 22), you may answer an intercom call 
from anywhere in the room, or you may lift the handset for a 
private conversation. 
D. 
STATION-TO-STATION CALLING 
3.05 Intercom calls can be placed from one station to another. 
One of the two available intercom channels is selected auto- 
matically when a DSS key is pressed. 
3.06 If both channels are busy, you will receive a busy signal 
and the HOLD key will light. While the intercom paths are busy, 
C.O. calls may not be transferred. 
3.07 To place an intercom call: 
(1) Lift the handset and listen for the intercom dial tone. 
 
(2) Press the DSS key. If the called station is idle, both 
parties will hear one double tone, .
