DATA SYSTEMTL-130500-1001
13.0 The PD-200 data option must be ordered as a custom
system. When ordering the data system, first complete a frame
layout worksheet. The frame layout worksheet is located in the
Hardware Ordering Guide (FB-41640). After the layout sheet
has been completed, fill out the hardware editing sheets (FM-41460). Submit copies of the completed sheets. Information for
completing the layout sheet is given in Figure 13.1. Notes that
provide an explanation of information in Figure 13.1 follow:
NOTES:
1. Determine number of 
DFP/APM, APM, SPM low-speed and
SPM high-speed connections.
a. Determine number of VPLO cards and/or VP20 cards used
for 
DFP/APMs, APMs, and low-speed SPM connections.
b. Determine number of 
VPLl cards and/or VP21 cards used
for SPM high-speed connections. Since the 
VPLl or VP21
cards control the system’s high-speed data links, it is
recommended to configure and order a back-up card for
connection to the PDN (Public Data Network).
c. There is a system limit of 8 VPLC (any type) per file and16
VPLC (any type) per system maximum
2. Maximum number of 
LPBs for this release is two. Each LPB
can support up to 12,000 mini-packets per second.
3. ADMP A and C, UCB, PR, and 
PBEiT4. See voice ordering section for further details.

ATTENDANT15.0 The Attendant Console (Figure 15.1) is a compact,
CONSOLEmicroprocessor-controlled, desk-top console unit. It provides
control and flexibility for processing calls through the system
while on-line (in use). The user can place the console in other
control modes during nightime, maintenance, or unattended
periods.
The system supports a maximum of two Attendant Consoles.
The Attendant Consoles are remotely located from the equipment
cabinets. The Attendant Console contains compact electronics
and all controls and indicators needed for complete monitoring
and control of calls through the system. Both incoming and
outgoing calls can be answered, extended, camped on, put
on hold, or released from the console by depressing various
pushbuttons.
Each Attendant Console uses five EPROM (Erasable
Programmable Read-Only Memory) chips that contain the
generic software that determines the functional operation of the
Attendant Console.

Emitting Diode15.1 The Attendant Console interfaces with the system via the
PLCC and the ATT12 cards, located in 
PCtvlUS (Pulse Code
Modulation Universal Slots). It is recommended to place these
cards in adjacent card slots for easier installation and
maintenance.
0 PLCC (line circuit card) FB-17254-A provides the analog
channel for both DTMF signaling and voice communication
between the Attendant Console and the system. The analog
channel is connected to the system via tip and ring
connections to one port of the line card.
0 ATT12 (Attendant Interface) FB-17208-A provides the digital
data link channel connection to the system. The data link is a
full-duplex, 1,200 baud, current loop.
NOTE: The 
ATT12 and PLCC cards are described on Table 3.6.
Attendant Console interface cabling is described in 
TL-130300-l 001.
15.2 The Attendant Console includes the following features:
0 26-pushbutton keyboard
0 12 key dial pad
0 Call-waiting queue lamp
8 Optional headset/handset and associated jacks
l Connect to BLDU (Busy Lamp Display Unit) (Optional)
0 32-alphanumeric character LED display for displaying class
of service, equipment identity, type of call, dialed digits, time of
day, and system alarm information
15.3 An alphanumeric, 32-character display LED (Light
Emitting Diode), located across the top of the Attendant Console,
provides call information to the user including the type of call,
class-of-service marks, and equipment identity. The type of
call indication is present as long as the attendant is servicing the
call and during attendant recalls. Possible call types include FX
and Tie. System fault alarm information is displayed in the type
of call position if the ALARM pushbutton is depressed.

Attendant Call
DistributionSVR 5210TL-130500-1001
15.4 The Attendant Console has two sets of headseuhandsetjacks: a rear jack for supervisory monitoring and a side jack for
attendant use.
The headset/handset must be plugged in for the Attendant
Console to operate in the on-line mode. Should the 
headset/handset be unplugged, the Attendant Console defaults to the
Night 1 mode, and is considered busy by the operating system
software.
Diagnostic self tests can be initiated while in the Night 1 mode.
15.5 For dual Attendant Console operation, attendant-seeking
traffic is distributed evenly between the two attendants. When the
headset/handset is removed from the jack, the Attendant Console
is considered unstaffed and the call is diverted to a second
Attendant Console (the Attendant Console with the
headset/handset removed is placed in the 
Nl mode of
operation). Night answer modes Nl and N2 are data base
programmable to provide UNA (Universal Night Answer), PNA
(Predetermined Night Answer), or a combination of both night
answer services. Removing the headset/handset turns off all
lamps on the console and sends an unstaffed message to the
system. All calls to this console are then cleared.
15.6 Calls to the Attendant Consoles are distributed evenly, but
the number of loops used for incoming calls is a programmable
system feature. Either 1, 2, 3, or 4 loops may be programmed to
receive incoming calls. Do not to enable the fourth loop since
this could prevent the attendant from making an outgoing call
during an emergency.
Regardless of the selected number of loops programmed for
incoming calls, console 1 receives the first call on LOOP 1,
console 2 receives the next call on LOOP 
1, and so on, until all
available consoles have a call on LOOP 1. Additional incoming
calls either ring into LOOP 2 on each available console (if
programmed), following the same sequence, or they are placed
in the call waiting queue until an incoming loop becomes idle on
any console. The system preferentially fills preceding loop levels
before either moving into the next higher loop level or placing a
call in Call Waiting Queue. When programmed for overflow, the
universal answer mode is also activated when the second 
call-waiting queue is reached.

							TL-130500-1001
In a single console operation, calls can automatically ring into
LOOP 1 through LOOP 4 sequentially, depending upon the
system programming. All calls will remain in the call waiting
queue until a loop becomes idle.
An attendant releases’ an active loop by depressing the POS’
RLSE, HOLD, or CAMP-ON pushbutton, or another LOOP
pushbutton. Upon release, the next call in the call waiting queue
is presented to the attendant.
For dual Attendant Console operation, attendant-seeking traffic
is distributed evenly between the Attendant Console positions.
Except for priority calls, all attendant-seeking traffic is queued
on a FIFO (First-In, First-Out) basis. Only one new call is sent
to the attendant at a time. The attendant can release from the
active loop by depressing the POS RLSE, HOLD, or CAMP-ON
pushbutton, or another LOOP pushbutton. When the button is
released, the next call in the call waiting queue will be sent to the
attendant.Attendant15.7 A 24-VAC transformer, connected to a local 115VAC
Console Bowerpower source or a-48 VDC power supply, powers the Attendant
Console.
See TL-130300-1001 for a description of the Attendant
Console power connections.
NOTE: Input to the Attendant Console should not exceed -54
volts DC.
