SECTION 2.00 GENERAL DESCRIPTION 
2.01 Operational Characteristics. The console, for local ap- 
plications, can operate efficiently up to 2000 feet (610 meters) 
away from the system while deriving power directly from the 
system’s power. For remote applications, the console can also 
operate efficiently up to 4000 feet (1219 meters) away from 
the system by deriving power from an optional AC-to-DC adap- 
ter externally located from the console housing. The cabling 
from the Main Distribution Frame (MDF) to the console loca- 
tion is accomplished by a single 2-pair (24AWG wire) cable. 
2.02 Physical Characteristics. The console’s circuitry is pack- 
aged in a modernly-styled plastic housing measuring 18.50 
inches (46.99 centimeters) in length, 10.42 inches (26.47 cen- 
timeters) in width, and 5.15 inches (13.08 centimeters) in 
height. The console consists of three major assemblies which 
are briefly described below and shown in Figure 2.00. 
a. Handset Assembly. The console comes equipped with 
a light-weight handset assembly containing the atten- 
dant’s receiving and transmitting circuits. The hand- 
set is attached to a six-foot cord terminated with a dual 
switchboard plug which in-serts into the connecting 
jacks. For convenience, one set of jacks is provided on 
the left and right side of the console housing. The two 
sets of jacks can also accept a headset assembly. When 
a headset assembly is required, the following types (or 
other electrically equivalent) are recommended: 
1. Plantronics: STARSET - Hy Gain Model. 
2. Roanwell: RS70 and RS71 Models. 
3. Northern Electric: VENTURA I (eouipped with ad- 
justable gain) Model. 
. . . 
Normally only one handset/headset assembly is used 
with each console due to loss of transmission power; 
however, a second handset/headset assembly can be 
used for training or monitoring purposes, providing that 
it does not contain any transmitting circuitry. 
b. Display Assembly. The upper portion of the console 
contains the display assembly which provides the 
necessary information on calls, as well as the ability 
to monitor system and console conditions. The display 
assembly is mounted on a single printed circuit (PC) 
module which is located behind a smoked-gray panel. 
This panel conceals the display indicators, except when 
illuminated, to permit indications to be more easily 
recognized. This assembly consists of one 
40-character alphanumeric display unit and 30 Light- 
Emitting-Diode (LED) indicators. 
c. Keyboard Assembly. The lower portion of the console 
contains the keyboard assembly which allows process- 
ing of calls and accessing of a number of special func- 
tion features. The keyboard assembly is mounted on 
a single PC module, located behind the console’s 
faceplate, and positioned in a slanting angle to reduce 
any glare which might be caused by high ambient light- 
ing conditions. The keyboard assembly consists of one 
digital 1Bbutton keypad and 34 non-locking function- 
type keys containing one internal red LED each. The 
audio tone speaker and volume control knob for the 
console’s audible signal are also included in the kev- 
board assembly. -

SECTION 3.00 CONTROLS AND INDICATORS 
A30808-X5051-CllO-l-6919 
issue 1, December 1984 
3.01 General. Figure 3.00 shows a typical console layout of 
the standard factory-assigned controls and indicators. The il- 
lustrated controls and indicators are described in the follow- 
ing subparagraphs according to their categorization. 
3.02 Console and System Indicators. The Console and Sys- 
tem Indicators, shown in Figure 3.00, are used to monitor sys- 
tem and console conditions. The indicators are described 
below according to their classification. 
a. TRUNK GROUP STATUS Indicators. Each attendant 
console is equipped with a total of 24 trunk busy LED 
indicators which provide visual indication on the sta- 
tus condition of trunks in a particular trunk group. 
These LED indicators represent trunk groups 1 through 
24 in the system. Trunk groups 0 and 25 through 31 
may not be assigned to the trunk group busy LED in- 
dicators; therefore, trunk groups that require a busy 
LED indicator on the console(s) should be assigned 
to trunk groups 1 through 24. The TRUNK GROUP 
STATUS indicators provide three illumination states to 
indicate the following conditions: 
LED extinguished - Indicates that the number of 
idle trunks remaining in that particular trunk group 
are greater than the customer-set threshold value. 
LED flashing (@ 60-IPM) - Indicates that the num- 
ber of idle trunks remaining in that particular trunk 
group have reached or exceeded the customer-set 
threshold value. 
LED steadily lit - Indicates that all trunks in that 
particular trunk group are busy. 
NOTE: The customer-set threshold value for each trunk 
group is entered as an absolute number of idle trunks 
remaining in the trunk group.) 
b. MAJ ALM (Major Alarm) Indicator. The MAJ ALM indi- 
cator is a single red LED which, when steadily lit, pro- 
vides visual indication that the SATURN System is in 
a non-operative state and the system’s failure transfer 
relay subsystem, if equipped, is active. Immediate 
maintenance personnel attention is required when the 
MAJ ALM indicator is steadily lit. Note that certain 
major alarm conditions could prevent the MAJ ALM in- 
dicator from being steadily lit. Refer to the applicable 
SATURN II or III EPABX Maintenance and Trouble- 
shooting practice for descriptions of the major alarm 
conditions. After the major alarm condition is cleared, 
the MAJ ALM indicator is extinguished and the power 
failure transfer feature returns to an idle state. 
c. MIN ALM (Minor Alarm) Indicator. The MIN ALM indi- 
cator is a single LED which, when steadily lit, provides 
visual indication that a minor alarm condition(s) has 
occurred and/or is present in the system and may re- 
quire maintenance personnel attention. Malfunctions 
causing minor alarm conditions can be shown in the 
Call Information Display by depressing the optional 
customer-assignable MIN ALM key. ALERT Indicator. The ALERT indicator is a single LED 
which, when flashing, provides visual indication when 
the console has received a call on one of the Call An- 
swer Keys. 
CW (Call Waiting) Indicator. The CW indicator is a sin- 
gle LED which provides visual indication when calls 
are waiting for service by the attendant. The CW indi- 
cator provides three illumination states to indicate the 
following conditions: 
LED extinguished - Indicates no calls waiting for 
service. 
LED flashing (@ 60-IPM) - Indicates between one 
and less than the customer-set threshold value of 
calls waiting for service. 
LED steadily lit - Indicates that the customer-set 
threshold value of calls waiting for service has 
either been equaled or exceeded. 
3.03 Call Information Display. The Call Information Display, 
shown in Figure 3.00, provides visual information on calls, as 
well as pertinent system conditions. This visual information 
is accomplished via a single 40-character alphanumeric dis- 
play unit with two associated LED indicators, SOURCE and 
DESTINATION. The Call Information Display shows the fol- 
lowing information: 
1. 
2. 
3. 
4. 
5. 
6. 
7. 
8. Call waiting condition, plus present date and time 
of day in standard or military time form. (Note: This 
call waiting display is shown when the console is 
in an idle state.) 
Call type (i.e.; INC, OPR, or RCL). 
Source (calling party) identity. 
Destination (attendant-dialed party) identity. 
Status condition of source and destination parties. 
Minor alarm conditions. 
Special feature functions. 
Standby Common Control Failure Display 
(SATURN Ill only) 
The associated SOURCE and DESTINATION LED indicators, 
via various illumination combinations, indicate how the infor- 
mation being shown in the alphanumeric display unit has 
been partitioned for display purposes. These illumination com- 
binations and their meanings are as follows: 
1. SOURCE-LED OFF and DESTINATION-LED OFF 
- 
Indicates all 40 characters display general sys- 
tem information. 
2. SOURCE-LED ON and DESTINATION-LED OFF 
- 
Indicates all 40 characters display source party 
information.

3.04 Audible Signal Volume Control Knob. The Audible Sig- 
nal Volume Control Knob, shown in Figure 2.00, is used to 
control the level of loudness of the audible signal emitted from 
the audio tone speaker. The audio tone speaker is used to 
announce the presence of calls on the Call Answer Keys. 
3.05 Dialing Keypad. The Dialing Keypad, shown in Figure 
3.00, is a digital 12-button keypad containing the digits 0 
through 9 and the symbols * and #. The Dialing Keypad is 
used to dial internal station numbers, outside telephone num- 
bers, and customer-assigned feature access codes. 
3.06 Call Answer Keys. The Call Answer Keys, shown in 
Figure 3.01, are four keys used to answer calls placed on the 
particular console by the system. These four keys are de- 
scribed below according to their classification. 
a. INC (Incoming) Key. The INC key is used to answer 
the following types of incoming calls: 
1. Incoming Central Office (CO) trunk call, automat- 
ic tie trunk call, or Direct Inward Dialing (DID) trunk 
call to Listed Directory Number (LDN) of the 
EPABX. 
2. Dedicated Incoming Trunk (DIT) call or DID trunk 2. Unanswered incoming trunk call previously extend- 
call, forwarded to attendant. ed to a station. 
3. DID trunk call to a vacant station or code intercept

tendant. 
The INC key contains one internal LED indicator that 
provides three illumination states to indicate the fol- 
lowing conditions: 
1. LED extinguished - Indicates no incoming-type 
calls to answer. 
2. LED flashing (@ 60-IPM) - Indicates one or more 
incoming-type call(s) to answer. 
3. LED steadily lit - Indicates the incoming-type call 
answered and presently connected. 
b. OPR (Operator) Key. The OPR key is used to answer 
the following types of operator calls: 
1. Station user dials 0. 
2. Station user dials for a specific attendant. 
3. Tie or Direct Inward System Access (DISA) trunk 
user dials 0. 
4. DID, tie, or DISA trunk user dials for a specific at- 
tendant. 5. Call from a direct attendant signaling line (i.e.;

The RCL key contains one internal LED indicator that 
provides three illumination states to indicate the fol- 
lowing conditions: 
1. LED extinguished - Indicates no recall-type calls 
to answer. 
2. LED flashing (@ 60-IPM) - Indicates one or more 
recall-type call(s) to answer. 
3. LED steadily lit - Indicates the recall-type call 
presently connected. 
d. ANS (Answer) Key. The ANS key is used to answer the 
next call queued from either the incoming, operator, 
or recall call queues according to the Attendant An- 
swering Priority feature. The ANS key contains one in- 
ternal LED indicator that provides two illumination 
states to indicate the following conditions: 
1. LED extinguished - Indicates no incoming-, 
operator-, or recall-type calls to answer. 
2. LED flashing (@ 60-IPM) - Indicates one or more 
incoming-, operator-, or recall-type call(s) to answer. 
3.07 Call Processing Keys. The Call Processing Keys, shown 
in Figure 3.01, are used to process calls, as well as to initiate 
features. These keys are described below according to their 
classification. 
a. SRC (Source) Key. The SRC key contains one inter- 
nal LED indicator that, when steadily lit, indicates when 
the connection is established between the attendant 
and the calling party. When the calling party is released 
from the console, the internal LED indicator is extin- 
guished. 
The SRC key may also be used to perform the follow- 
ing functions: 
1. To select the source party for an attendant-initiated 
call or access code to a feature. Depressing the 
SRC key when the console is in an idle state A30808-X5051-CllO-l-B919 
Issue 1, December 1984 
causes its internal LED to be steadily lit and allows 
initiation 
of a call or access to a feature. This func- 
tion is released by depressing either the RLS key, 
or the ATT RLS key or a flashing Call Answer key 
after completion of call or feature access. When 
this function is released, the internal LED in the 
SRC 
key is extinguished. Note that source selec- 
tion occurs automatically if dialing is begun from 
a console in an idle state without first depressing 
the SRC key. 
To perform a splitting function on a connected 
source-attendant-destination call. Depressing the 
SRC key when both source and destination par- 
ties are being shown on the Call Information Dis- 
play causes its internal LED to be steadily lit and 
performs a splitting function on the call. The atten- 
dant is then connected to the source party in a pri- 
vate conversation, while the destination party is 
split away from the call. This function is released 
by depressing, as required, one of the following 
keys (which extinguishes the internal LED in the 
SRC key): 
ATT RLS key or a flashing Call Answer key - 
To cancel the splitting function, release the at- 
tendant from the call, and establish a source- 
destination connection. 
RLS key - To release the source party from 
the call and establish an attendant destination 
connection. 
BOTH key - To restore the original source- 
attendant-destination connection. 
d) DEST key -To split-away the source party and 
estabilsh an attendant-destination connection. 
To release the source party. The sequence of 
depressing the SRC key, followed by the RLS key, 
releases the source party from either a source- 
attendant-destination or source-attendant connec- 
tion. In a source-attendant connection, the same 
release effect is obtained by depressing the ATT 
RLS key or a flashing Call Answer key. 
b. DEST (Destination) Key. The DEST key contains one 
internal LED that, when steadily lit, indicates when the 
connection is established between the attendant and 
the attendant-dialed party. The Call Information Dis- 
play provides the identity and status condition of the 
attendant-dialed party.When the attendant-dialed party 
is released from the console, the internal LED in the 
DEST key is extinguished. 
The DEST key may also be used to perform the fol- 
lowing functions: 
1. To select the destination party for a call currently 
active on the console. Depressing the DEST key 
when a source party is being shown on the Call 
Information Display causes its internal LED to be 
steadily lit and allows the attendant to dial the 
desired destination party. This function is released 
by depressing either the RLS key, or the ATT RLS 
3-5  
						

							SATURN EPABX 
Attendant Console General Description and Operating Instructions 
key or any of the Call Answer keys. When this func- 
tion is released, the internal LED in the DEST key 
is extinguished. Note that destination selection oc- 
curs automatically if dialing is begun without first 
depressing the DEST key and source party is be- 
ing shown on the Call Information Display. 
2. To perform a splitting function on a connected 
source-attendant-destination call. Depressing the 
DEST key when both source and destination par- 
ties are being shown on the Call Information Dis- 
play causes its internal LED to be steadily lit and 
pe,forms a splitting function on the call. The des- 
tination party is now engaged in a private conver- 
sation, while the source party is split away from the 
call. This function is released by depressing, as re- 
quired, one of the following keys (which extinguish- 
es the internal LED in the DEST key): 
a) ATT RLS key or a flashing Call Answer key - 
To cancel the splitting function, release the at- 
tendant from the call, and establish a source- 
destination connection. 
b) RLS key - To release the destination party 
from the call and establish a source-attendant 
connection. 
c) BOTH key - To restore the original source- 
attendant-destination connection. 
d) SRC key-To split-away the destination party 
and establish a source-attendant connection. 
3. To release the destination party. The sequence of 
depressing the DEST key, followed by the RLS key, 
releases the destination party from either a source- 
attendant-destination or attendant-destination con- 
nection. In an attendant-destination connection, the 
same release effect is obtained by depressing the 
ATT RLS key or a flashing Call Answer key. 
c. BOTH Key. The BOTH key is used to unsplit the source 
and destination parties during a split source-attendant- 
destination connection. Depressing the BOTH key 
when both source and destination parties are shown 
in the Call Information Display causes its internal LED 
to be steadily lit and a source-attendant-destination 
connection to be established. This function is released 
by depressing one of the following keys (which extin- 
guishes the internal LED in the BOTH key): 
a) ATT RLS key - To release the attendant from 
the call and establish a source-destination con- 
nection. 
b) RLS key -To release both the source and des- 
tination parties from the call. 
c) SRC or DEST key - To resplit the call as ap- 
plicable. 
d. RLS (Release) Key. The RLS key is used primarily to 
release either the source party or destination party, or 
both source and destination parties from the estab- 
lished connection. Depressing the RLS key when either 
3-6 A30808-X5052-CllO-l-B919 
Issue 1, December 1984 
the SRC, DEST, or BOTH key is steadily lit disconnects 
the applicable party or parties from the attendant con- 
sole connection. 
The RLS key may also be used to perform the follow- 
ing functions: 
To release a source-attendant or attendant- 
destination connection, depress the RLS key. This 
action releases the applicable party from the call. 
This same release effect is obtained by depress- 
ing the Al7 RLS key or a flashing Call Answer key. 
To restore the console to an idle state, after com- 
pletion of an attendant-initiated call or feature ac- 
cess, depress the RLS key. This same effect is 
obtained by depressing the An RLS key or a flash- 
ing Call Answer key. 
To cancel digits already dialed, depress the RLS 
key white dialing on the Dialing Keypad. This ac- 
tion cancels the digits already dialed. 
Note that the RLS key contains one internal LED which 
is used for maintenance purposes only. 
e. ATT RLS (Attendant Release) Key. The ATT RLS key 
is used primarily to release the attendant from a con- 
nected source-attendant-destination call. Depressing 
the ATT RLS key, when both source and destination- 
parties are shown on the Call Information Display, 
releases the attendant from the call and establishes 
a source-destination connection. In the event the con- 
nected source-attendant-destination call is undergoing 
a splitting function, depressing the ATT RLS key can- 
cels the splitting function, releases the attendant from 
the call, and establishes a source-destination connec- 
tion. In both cases, this same effect is obtained by 
depressing any flashing Call Answer key. 
The ATT RLS key may also be used to perform the fol- 
lowing functions: 
1. To release a source-attendant or attendant- 
destination connection, depress the ATT RLS key. 
This action releases the applicable party from the 
call. This same release effect is obtained by 
depressing the RLS key or a flashing Call Answer 
key. 
2. To restore the console to an idle state after com- 
pletion of an attendant-initiated call or feature ac- 
cess, depress the ATT RLS key. This same effect 
is obtained by depressing the RLS key or a flash- 
ing Call Answer key. 
Note that the ATT RLS key contains one internal LED 
which is used for maintenance purposes only. 
f. FLASH Key. The FLASH Key is used to simulate a 
hookswitch flash to request operator assistance on out- 
going calls via tie and toll connecting trunks. 
g. LOOP Keys. The LOOP keys, numbered 1 through 4, 
are simulated loop circuits which act as private con- 
sole hold locations for placing calls on hold. Depressing  
						

							SATURN EPABX 
Attendant Console General Description and Operating instructions A30808-X5051-CllO-l-B919 
Issue 1, December 1984 
a LOOP key places the party or parties shown on the 
Call Information Display in a holding state. This hold- 
ing functions is released by depressing the appropri- 
ate LOOP key which reconnects the held party or 
parties. Each of the LOOP keys contains one internal 
LED that provides four illumination states which indi- 
cate the following conditions: 
1. LED extinguished - Indicates that the particular 
LOOP key is idle. 
2. LED winking (@I 125-IPM) - Indicates that the par- 
ticular LOOP key is busy with a party or parties on 
hold. 
3. LED flashing (@ SO-IPM) - 
a) When a single party is being held - indicates 
that the holding time has exceeded the 
customer-set value for such and automatic 
recall to the attendant has been initiated. 
b) When dual parties are being held (i.e., locked 
loop connection) - indicates that either a sta- 
tion user is manually recalling the attendant; 
or an incoming trunk call involved in a series 
call is automatically recalling the attendant. 4. LED steadily lit - Indicates that the attendant is 
now reconnected to a party or parties on that loop. 
Single party calls held on attendant hold loops shall 
be available for direct pick-up by stations in a manner 
similar to a parked call. 
To retrieve an attendant held call, the station user with 
the proper class-of-service goes off hook, keys the At- 
tendant Call Hold Retrieve access code followed by 
the Attendant Call Hold location numbers where the 
held call exists. The Call Hold location numbers are 
shown in Table 3.00. 
3.08 Standard Feature Keys. The Standard Feature keys, 
shown in Figure 3.01 are three keys containing the standard 
factory-assigned feature equipped with each console. These 
feature keys are described below according to their classifi- 
cation. 
a. NIGHT Key. The NIGHT key is used to place the con- 
sole in the “night service mode of operation” at the 
end of a business day. Depressing the NIGHT key 
causes its single internal LED to be steadily lit. All new 
and pending calls are automatically distributed to the 
UNA feature and ANA or SNAP position(s) as required 
or to another active console in the system.

Attendant Console General Description and Operating Instructions 
b. TIME (Display Time) Key. The TIME key is used to show 
the time-of-day (i.e., hours and minutes in standard 
12-hour AM/PM or 24-hour time) on the Call Informa- 
tion Display. Although the Call information Display pro- 
vides the current date and time-of-day when the 
console is in an idle state or in between calls, depress- 
ing the TIME key when connected to a call prompts 
the time-of-day for three seconds. When the three sec- 
onds expire, the call data previously shown on the Call 
Information Display is redisplayed unchanged or up- 
dated as required. 
Note that the TIME key contains one internal LED 
which is used for maintenance purposes only. 
c. AUD ON/OFF (Audible On/Off) Key. The AUD ON/OFF 
key is used to activate or deactivate the audio tone 
speaker. This speaker emits the console’s audible sig- 
nal that announces the presence of calls on the Call 
Answer keys. Depressing the AUD ON/OFF key causes 
its single internal LED to be extinguished and deacti- 
vates the console’s audible signal. To activate the au- 
dible signal, redepress the AUD ON/OFF key. This 
action causes the key’s internal LED to be steadily lit. 
3.09 Optional Feature Keys. The Optional Feature keys, 
shown in Figure 3.02, are a group of 18 vacant keys which 
may be assigned, via CMU procedures. These optional fea- 
ture keys are described below according to their classification. 
a. ACCT (Account) Key. The ACCT key relates to the Sta- 
tion Message Detail Recording (SMDR) account code 
feature. The ACCT key is used to either display the cur- 
rent standard (or default) account code or to enter a 
new account code for both incoming and outgoing 
calls. The account code is cost accounting or client 
billing code information in numerical digits variable in 
length, up to a maximum of 11 digits, as per customer 
option via CMU procedures. 
A new account code is entered by depressing the 
ACCT key. This action causes the Call Information Dis- 
play to show the current standard account code as- 
sociated with the connected call that has an associated 
SMDR call record. The system is then ready to accept 
the new account code as dialed on the Dialing Key- 
pad. When the required digits of the new account code 
are dialed, the current standard account code being 
displayed is blanked and the dialed digits are shown 
on the Call Information Display. Depressing any other 
console key (e.g., RLS, BOTH) applies the dialed new 
account code to the call. This action causes the ap- 
propriate Call Information Display data to be restored. 
If no digits are dialed, the current standard account 
code is retained and applied to the call after depress- 
ing any other console key. This action allows the at- 
tendant to display the current standard account code 
associated with a call without having to enter a spe- 
cial account code. If a mistake is made while dialing 
a new account code, redepress the ACCT key to can- 
cel the dialed digits and allow redialing of the new ac- 
count code. Also, if the ACCT key is depressed to 
display or enter an account code for a call that has no 
associated SMDR call record, Negative Acknowledge- 
ment (NAK) tone is heard. Note that if more than one 
special account code is dialed by either the attendant, A30808-X5052-CllO-l-6919 
Issue 1, December 1984 
station/keyset user, or both, the last special account 
code dialed is applied to the call. 
Note that the ACCT key contains one internal LED 
which is used for maintenance purposes only. 
ACOF (Attendant Control of Facility) Key(s). The Op- 
tional Feature keys can be assigned to provide atten- 
dant control of certain facilities available through the 
system. Assignment of the ACOF key(s) is by individual 
console. By using the ACOF key(s), the following fa- 
cilities may be restricted: 
1. Paging access 
2. Dial dictation access 
3. Conference circuits 
4. Code call access. 
Depressing an ACOF key causes its single internal 
LED to be steadily lit and restricts access to that par- 
ticular facility. When a station user dials the access 
code or a Digital Premium Instrument (DPI) user acti- 
vates the feature button for the facility under attendant 
control, the call is routed to the console as a recall. 
Once the recall is answered, the Call Information Dis- 
play shows the access code of the controlled facility 
and the source party (i.e., calling party) attempting to 
access that particular facility. At this point, the atten- 
dant can extend the controlled facility to the calling 
party by dialing the displayed access code. To release 
this function, redepress the applicable ACOF key. This 
action extinguishes its internal LED and allows sta- 
tionlkeyset users to again access that particular facility. 
ACOF-TG (Attendant Control of Facility-Trunk Group) 
Key(s). The ACOF-TG key(s) can be assigned to pro- 
vide attendant control of trunk groups. Depressing the 
ACOF-TG key(s) causes its internal LED indicator to be 
steadily lit and restricts access to that particular trunk 
group. When a station user dials the access code of 
or seizes a trunk from the controlled trunk group, the 
call is routed to the console as a recall. Once the recall 
is answered, the Call Information Display shows the 
access code of the controlled trunk group and the 
source party (i.e., calling party) attempting to access 
the particular trunk group. At this point, the attendant 
can extend the controlled trunk group to the calling 
party by dialing the displayed access code digits. To 
release this function, redepress the applicable ACOF- 
TG key. This action extinguishes the LED and allows 
station users to gain access to the particular trunk 
group. 
CONF (Conference) Key(s). The Attendant Conference 
feature allows the attendant to establish a conference 
connection between a combination of up to seven par- 
ties, six of which may be trunks, by using the CONF 
key. The attendant maintains control of this conference 
until it is released. 
An LED is associated with each CONF key and pro- 
vides four illumination states which indicate following 
conditions: 
1. LED extinguished - Indicates the CONF key is idle 
and may be used to establish an attendant- 
controlled conference.
