1. GENERAL
1.1 This section providesgeneral description
and installation information for the
SanIBar 319A Key Service Panel as shown
in Figure 1. The SB319A providesmount-
ing for up to 15standard linecards such as
the SB4000F or WE400.
The SB319A is
equivalent to the WE584 panel butwith
greater flexibility and capacity. The panel
utilizes the SB6606A Solid State Interrup-
ter (18-pinplug-incard) mounted in the
end card position for the interrupter func-
tions. The SB319A Panel also acceptsthe
SanIBar 6608A RingingGenerator which
plugs into an 18-pincard position. For
maximum utilizationof card positions, the
SB319A may be strapped as amaster panel
that would mount the interrupter, ringing
generator, and 13 line cards; and additional
panelshavingthe maximum of 15 line
cards per panel with power distribution
from the master panel.

Fig. 1 SB319A Key Service Panel
Signal connections from the C.O. and to
the telephone stations are through three
standard telephone connectors on the rear
of the unit with pin assignments identical
to that of the WE584 panel. Power con-
nections are toscrew terminals located
at
the rear of the unitalong with the power
fusing. The panel mounts in
a standard
23" rack.
Inaddition to mounting standard line cards,
the SB319A Panel also mounts special cards
such
as the SB423A Manual Intercom card
(equivalenttoWE401), SB4200A Music-on-
hold Line card, or the SB4100A Multi-
station Control Line Card. The special sig-
nal inputs associated with the cards such
as STC or music are interfaced through
a
telephoneconnector on the rear of the
panel (avoidingspecial panel modification
as with the WE584).

INSPECTION
Inspect the unit thoroughly as soon as
possible after delivery. Visually inspect
for broken and loose wires, or chassis
damage. Ifany part of the unit has been
damaged in transit, report the extent of
damage to the transportation company
immediately.
4. MOUNTING
The SB319A Key Service Panel is designed
for standard
23" rack or apparatus mount-
ing fixtures such
as the WE 16C wall mount
apparatus fixture. The panel has mounting
flanges with two slotted holes in each side.
The slotted holes allow maximum flexibili
ty in positioning of the unit up or down
relative toother panels. Because of the
unit's light weight, only four mounting
screws are needed and may be positioned
anywhere in the slots.
The cable interface is designed for rear
panel entry from the right side. If installing
in
a hinged apparatus mounting, the equip-
ment gate should swing out to the right for
ease of cable entry. A cable tie is provided
for securing the cable.
5. INSTALLER CONNECTIONS
5.1 Line Cards (SB4000F)
The SB319A is strapped (fromthe factory)
for mounting up to 14 standard line cards
(SB4000F, WE400, or equivalent). Position
15 is strapped to accept the SB6606 Solid
State Interrupter. No additional or special
wiring is required for installation. For
additional information on the operating
characteristics of the SB4000F, refer to
C D-4000-000.
In high density installations where maxi-
mum line card capacity is required, position
15 may be strapped for line card use (see
Fig. 3). By moving the six straps normally
used for the interrupter option,
a maximum
line capacity of 15 per panel is possible.
Depending on the current loads,
2 or 3
additional panels may be strapped for maxi-
mum line capacity with power and inter-
rupter signals distributed from the master
SB319A panel. See Section 5.4 for power
distribution.
NOTE: TO AVOID POSSIBLE CARD
DAMAGE, VERIFY THAT THE
SB319A STRAPS HAVE BEEN
MOVED TO THE LINE POSITION
BEFORE INSTALLING A LINE
CARD IN POSITION 15.
5.2 Solid State Interrupter (SB6606A)
The SB319A comes factory strapped for
use with the SB6606A Interrupter. The
interrupter plugs intocard position 15.
Necessary fusing and signal distribution is
prewired with the addition of six straps
(22AWG bus wire) located on the rear
panel. (See Fig. 2 for strap information).
3

No additional installerstrapping is required
on the SB319A to use the SB6606A Inter-
rupter.
If the SB6606A is to be used for heavy
duty operation, the interrupter must be
strapped for additional input/output pins.
Referto CD-6600-000for information on
the interrupter strap options and load
capacity. The SB319A panel wiring
is
capable of handlingthe heavy-duty inter-
rupter. For interrupter signal distribution
to other panels, refer to Section5.4.
5.3 RingingGenerator (SB6608A)
The SB319A is wired so that the SB6608A
Ring Generator ( 105VAC) may be option-
ally used in card position 14. The generator
is used in lieu of an external ringingsupply
and
its output may be distributed through
the rear terminals toother panels (see
section 5.4). To use the SB319A panel
with the SB6608A strap RG to RGI with
bus wire (see Fig.2). For additional infor-
mationon the SB6608A, refer toCD-6608-
000.
5.4 Power Distribution
Power input to the SB319A Panel
is
through screw terminals locatedon the rear
panel. These screw terminals also serve as
the interrupter and ringinggenerator out-
putsfor distribution to other panels. Sec-
tion 2.2 provides referencedesignation
definition for these terminals. Make con-
nectionsto the screw terminals using22
AWG min. wire and routethrough the
wire guides provided.
The power distribution for the panel pro-
vides four independent grounds (talk
battery ground-AG,Signal battery ground-
BG, Lamp Ground-LG,and Ring Ground-
RG). The BG (Al),LG and RG (BI)
grounds are also distributed tothe station
apparatus for each linethrough the rear
telephoneconnectors. The grounds may be
left isolatedor commoned
at the screw
terminals.
To use one SB319A Panel as amaster panel
with interrupter (orringinggenerator), dis-
tribute power and interrupter signals to
other panels (with linecards only
- see
section 5.1
) by connecting betweenpanels
the common labeledterminals. For exam-
ple, the lamp wink function, LW, from the
master panel would be distributed by
"daisy-chaining" all the LW-terminalsof
the panels includingthe master panel. Make
similar connectionsfor the remainingter-
minals (see Figure
4). (Note: The LB, LG,
LW, and the LF functions are providedwith
two terminals for handlingheavy current
loads. If22 AWG wire
is used, two wires
should be used per function
- one to each
terminal).
5.5 C.O. and Station Connections
The signals from the C.O. and tothe station
apparatus are interfacedthrough the three
telephoneconnectors
(J 16-18)located on
the rear panel. The panel will accept stan-
dard telephonecables such as the A75A-
type multiheadcable. Pin assignments at
the connectorsare the same as the WE584
panel. The cables are intendedfor distri-
bution to 66-typeconnecting blocks using
standard practicetermination following the
normal color codes. Table
I gives pin as-
signmentsand where the signals will appear
at these feature blocks.
5.6 Music-On-Hold
(SB4200A)
The SB319A Panel is designed to accommo-
date the SB4200A Music-on-HoldLine
Card. Music input to the SB4200A
is
through Pins3 and 18of each card. With
the Option Plug installed, Pins
3 and 18 are
bussed on lines 2through 15 and appear at
the MOH terminals inthe rear panel. Con-
nect an isolatedtwisted pair of wires from
the music source to these terminals. Since
Pins3 and 18are not used on
a standard
linecard (SB4000F or WE400, the
SB4200A card may be mixed with the
SB4000F cards inthe same panel. For
additional information on the SB4200A,
refer to CD-4200-000.
The SB319A Panel
is normally wired such
that position 1may be used for manual
intercom. Since the manual intercom card
(SB423A)requirestalk battery (AB, AG)
on Pins3 and 18, this position is not in-
cluded in the Option Plugbussing. How-
ever, if MOH
is desired for position l also,
simply strap MOH1toABI, MOH2 to AG1
as shown in Fig. 3. Connect the music
source
as before. The talk batterv connec-
tions tothe panel must be removed.
For applicationswhere the individual music
inputsof each card must be interfaced, the
OptionPlug must be removedas described
inSection 5.10.
4

1 5.7 Manual l ntercom (SB423A)
The SB319A Panel is wired so that Position
1will also accommodate manual intercom
when required. Nostrapping
is required on
the SB319A. Pins 3 and 18required for
talk battery are prewired tothe fused AB,
AG input terminals on the rear panel.
Therefore, Position 1may be used for a
manual intercom circuit by supplying talk
battery tothe terminals. Talk battery does
not normally distribute to any other posi-
tions with or without Option Plug installed.
Iftalk battery
is desired to all positions,
strap AB1 to MOH1, AG1 to MOH2 as
shown in Figure3. Disconnect the music
source. The manual intercom card may
now be installed in any position. Connect
the talk battery supply as before. For more
informationon the SB423A, refer to
CD-0423-000.
For special installations where it is desked
tohave more than one manual intercom
card (SB423A, WE401, or equivalent) per
panel mixed with special feature linecards
that also use pins3 and 18, removethe
Option Plugfrom the 319A and install a
cablefor distributiontoafeature block
as
described insection 5.1 0. The individual
pins3 and 18of all 15positions will appear
at the feature block as given inTable I I.
Connectthe power supply talk battery
output tothe 319A terminals (AG, AB)
at
the rear of the panel. This will provide a
fused talk battery to pins3 and 18of
position 1which will also appear
at the
feature block. To provide afused talk
battery toother positions, simply strap
at
the feature block from pins 3 and 18of
position 1tothe other pins 3 and 18
desired.
Usingthe above procedure, any combina-
tionof manual intercom cards may be
mixedwith special feature linecards such
as music-on-hold, (SB4200A) or off-
premise extension (SB4100A). For instal-
lations where pins 3 and 18are used for
intercom talk battery only, and not for
any other features, the talk battery may be
distributed toall 15 positions with the
Option Plug installed and two straps added
tothe rear panel as shown in figure 3.
5.8 STC Interface
Where STC-type interface
is required, it
may be necessary to interface Pin 3 or 18
(suchas with the SB4000F which utilizes
Pin 3 for STC). Removethe Option Plug
and install
a cable for distribution as de-
scribed inSection 5.10. Nopanel modifi-
cation
is required.
5.9 Multistation LineCard (SB4100A)
The SB319A Panel is wired so that the
SB4100A cards may be installedwithout
panel modification. The SB4100A utilizes
Pin 18as a special signal lead (AER)that
is
cross connected betweenSB4100A's. To
interface Pin 18, remove Option Plugand
install acable for distribution
as described
inSection 5.10. Refer toCD-4100-000for
additional information on the SB4100A.
5.10 Option Plug (ED-0319-000)
The Option Plug for the SB319A Panel
is
suppliedwith the unitand is installed in
the rear panel telephone connector
J 19.
For normal installations, the Option Plug
will remain installed. The Option Plugpro-
vides abus of Pins 3 and 18for positions 2
through 15. This allows ease of music dis-
tribution for these positions, or for special
applications
as described inabove sections.
For special installations where
it is neces-
sary to interface Pin3 or 18of the individ-
ual lines, the Option Plug
is removed (e.g.
a mixture of SB4200A MOH cards and
SB4000F linecards usingSTC). l nstall a
standard A25B-type telephonecable and
distribute to
a 66-typeconnecting block.
Refer toTable
I I for pinassignments and
where leads appear at the feature block.
By cross connecting at this distribution
block,
it is possible to achieve MOH, STC,
manual intercom, etc. with any combina-
tionof card positions in the same panel.
6. TESTING
6.1 Iftrouble is encounteredwith the SB319A
Key Service Panel installation, check that
all installer connections or strappingop-
tions have been made properly. Also check
the power connectionsand fuses. Refer to
the individualcircuit descriptions for test-
ing of the cards. Other than fuses, the
SB319A contains no electrical components
that are normally considered subject to
failure. However, possiblewire breakage
or poorwire terminations may be verified
using normal continuity checkingproce-
dures with astandard multimeter (Simpson
236 or equivalent).
6.2 The SB319A
is warranted for a of
two years from date of purchase.
