5210SER CALL (SERIES CALL). Depressing this pushbutton after extending an
incoming call automatically causes the trunk to recall the attendant when the
station hangs up so the trunk can be extended to the next station in the series
call sequence. Alternatively, the attendant can call or be called from a station
(or have a station diverted to the Attendant Console due to an ACOF
restriction on an accessed trunk group) and extend a trunk to the station using
this pushbutton, re-initiating the automatic recall sequence to notify the
attendant that the trunk is available for the next user. The LED on indicates
action confirmation.
DEST RLS (DESTINATION RELEASE). Allows release of a called station or
trunk if a dialing error is made or a busy signal is received.
HOLD. Used to place a call in a waiting condition (on hold) until the attendant
can return to the call.
CAMP-ON. Allows placement of an incoming call in a waiting condition if the
called station is busy. When camp-on is used, the system automatically
extends the calling party to the called station when the called station becomes
idle.
LOOP 1 through LOOP 4. LEDs which indicate status of the loop.
START/STOP. In the START mode, this pushbutton activates the keypad and
provides dial tone and in the STOP mode, removes tick tone on outgoing
calls.
POS RLSE (POSITION RELEASE). Allows the attendant to release from any
type of call.
Class-of-Service Display. When a LOOP pushbutton is depressed to
answer an incoming call from a station or tie line, a one-digit display
indicates the displayable class of service (0 through 
9), and a two-digit
display indicates the N-displayable class of service (00-15) of the incoming
call. In a no-answer situation, the class-of-service display of the called
station appears after the LOOP pushbutton is depressed.
The class-of-service operation allows/disallows access to trunks and
features of the system. On a per-line basis, each line is marked with a class
identifying the line as 0 of 9 displayable classes of service and 00 of 15 
N-displayable classes of service.If a line with a restricted access code as a
function of classmark is dialed, the call is routed to an intercept facility
(recorded announcement, attendant, reorder tone etc.). The displayable and
N-displayable classes of service are displayed at the Attendant Console
every time the line is serviced by an attendant.
Displayable Classes of Service. The following can be combined, as desired,
to establish 10 types of call combinations that can be allowed or disallowed
as displayable classes of service.
(a)Dictation equipment access
(b)Meet-me conference access

Trunk or Station Display. A four-digit display of the trunk or line identity that
appears in the variable left portion of the display-characters field. When the
LOOP pushbutton is depressed to answer a call from a station or a tie line,
this four-digit display gives the number of the calling station or calling trunk.
The number of the called station in camp-on, busy, and no-answer
situations is displayed when the LOOP pushbutton is depressed.
Type-of-Call Displays. A display of predetermined messages that appear
in the fixed portion (right) of the display characters field (e.g., INFORMATION,
FX, NO ANSWER, etc.).
NOTE:The left 16 characters display variable data: line data, class-of-service data, etc. The right 16 characters display fixed
predetermined messages and input from the keypad.
LOCAL. Indicates an incoming CO call. The associated LOOP LED flashes
at 120 IPM.
INFORMATION. Indicates that a station desires assistance from the attendant
and has dialed 0. The associated LOOP LED flashes at 30 IPM.

display flashes at 60 IPM. The associated LOOP LED winks at 60
IPM.

SERfES CALL. At the completion of an incoming series call, the station hangs
up and the attendant is called. On answer, the SERIES CALL message and
the trunk number appear on the display, and the attendant can converse with
the calling party. At the completion of an outgoing series call, the station
hangs up, the trunk is released, and the attendant is called. On answer, the
SERIES CALL message flashes on the display along with the previous caller’s
station number and COS.
NO 
AIUSWER. Provides for answering a call for service resulting from a time
out on an unanswered call. The type of call could be a normal 
attendant-extended call (information or incoming), delayed call, camp-on call, or
station-transferred call (transferring party on-hook) either busy or
unanswered. The associated LOOP LED flashes at 60 IPM.
STILL BUSY. Refers to a camp-on call remaining busy for a predetermined
period (data base programmable), and the call being diverted to the attendant
or an attempt to transfer a call to a busy or unequipped device. The
associated LOOP LED flashes at 60 IPM.
TIE 
LIINE. Indicates an incoming tie-line call. The associated LOOP LED
flashes at 120 IPM.
FX (Foreign Exchange). Indicates an incoming call from a foreign exchange.
The associated loop LED flashes at 120 IPM.
INTERCEPT. Available when required. The associated LOOP LED flashes at

5210a/a7Most of the pushbuttons on the keyboard are depressed and
released to perform a function. The PAGE and BRK IN
pushbuttons are exceptions, however, and must be held in
the depressed position for the duration of the function. When
released, these pushbuttons are automatically cleared.
The fixed portion of the display is cleared when the
START/STOP key is depressed to enter digits. Then each
pushbutton entry on the keypad is displayed in this portion of
the display. If more than 
16 entries occur, the input digits
are scrolled off of the 16-character display on a first-in,
first-out basis. (This situation is likely to occur during group
speed-calling 
,ipdates. )
If two keys are depressed simultaneously, neither key is
recognized. Keys operate in a two-roll-over mode. In the
page or break-in case, the appropriate key is held down
while the function is activated. The depression of any other
key that occurs while a page or break-in is in effect, is
ignored. The page or break-in key release code is sent
before the rolled-over key is processed.
Certain combinations of key activations are illogical and
should not occur. A key activation is indicated by the
associated key LED being on (or flashing). If the attendant
attempts an illogical combination, the latest key depressed is
ignored.
All pushbuttons are nonlocking. All 
LEDs light, with the
exception of HOLD, DEST RLS and CAMP ON.

							TL-130100-10074.3Headset/HandsetThe 
headset/handset can be plugged into the left side or the right rear of the
Attendant Console. When the 
headset/handset is not inserted, the Attendant
Console functions in the unstaffed mode. All 
LEDs are off and the appropriate
unstaffed message is automatically sent to the system. When the Attendant
Console is in the unstaffed mode, the user can request specific stand-alone
maintenance diagnostics from the Attendant Console keypad. These
diagnostics test all of the displays 
(LEDs and alphanumeric display), display
Attendant Console parameters, and show the contents of the various internal
registers. Refer to Section TL-130200-I 001 for diagnostic procedures.
4.4Multiple Attendant Console OperationWhen two Attendant Consoles are used, one is designated as the master.
The master Attendant Console provides control of the night-answer
selection.
Each Attendant Console is assigned a directory number so calls can be
directed to a specific Attendant Console. If one Attendant Console calls the
other Attendant Console, the call is placed at the top of the called Attendant
Console call-waiting queue.
4.41Call-Waiting QueueCalls are generally distributed evenly to the Attendant Consoles. Attendant
Console 
1 receives the first call and Attendant Console 2 the next. When the
Attendant Consoles remain busy until the second level in the call-waiting
queue is reached, the CALL WTG 
LEDs on the Attendant Consoles flash.
(Option: If the system is programmed for overflow, the 
universal-night-answer mode also is activated when the second call-waiting queue is
reached.)
4.42Queued-Call DiversionIf the operator at an Attendant Console other than the master Attendant
Console enters into the night-answer mode and the second level of the
call-waiting queue is reached, the operator can divert calls one at a time to
the Attendant Console by depressing the flashing CALL WTG LED. The
operator can then process calls until the overflow is relieved and still remain
in the night-answer mode.
