DISTRIBUTION FRAME (MDF) and any optional peripheral equipment. 
2.1 Comtections between the trunks, station instru- 
ments, external equipment, and the station and trunkcir- 
cuit cardsare made at the MDF. The MDF is made up of 
industry-standard, 66Ml-SO-type terminal blocks and, 
if using Tl Cards, eight-conductor (RJ4gC) modular 
jack assemblies. Bridging clips are used on all terminal 
blocks to complete the connections. As many as 54 
blocks maybe needed, including any combination of the 
following: A. STATION CONNECTIONS 
2.3 For each keyset, analog DSS/BLF Unit, Attendant 
Computer Console, single-line set, and playback 
device, three-pair (24 AWG) twisted cable is run from 
the station location to the MDF. All station ,cables are 
terminated on blocks at the MDF and on six-conductor 
modular jack assemblies at the station locations. 
NOTE: It is recommended that three-pair twisted cable 
and six-conductor modular jacks be used for all station 
connections. This allows the various types of station in- 
struments to be easily interchanged if necessary. How- 
ever, if desired, ESLSs, SLIs, single-line DI’MF sets, 
and playback devices can be installed using one-pair 
twisted cable and four-conductor modular jacks.

the cables attach to the male connectors on the station 
cards in the cabinet. 
2.5 To meet Part 15 of FCC Regulations, all station 
cables must be equipped with ferrite beads. ‘Iwo ferrite

B. TRUNK CONNECTIONS 
2.6 The CO, DID, and B&M trunks are terminated on 
telephone company RI-type blocks, as required by FCC 
regulations. Cross-connect cable is used to connect the 
RI-type blocks to the CO, DID, and B&M terminal 
blocks on the MDF. The trunks are then connected to the 
Loop/Ground Start Cards (LGCs), Loop Start Cards 
(LSCs), Inward Dialing Cards (ID&), and/or B&M 
Cards (BMCa) using industry-standard, 25pair cable. 
Female Xl-pin amphenol-type connectors on the cables 
attach to the male connectors on the cards. 
2.7 To meet Part 15 of FCC Regulations, all trunk 
cables must be equipped with ferrite beads. Two ferrite 
“split” beads (two half beads) are installed on each 
25pair cable just below the amphenol-type connector. 
The beads help to reduce electromagnetic interference 
@Ml) and radio frequency interference (RFI). 
NOTE: Bach ferrite split bead, which is actually half of 
a full bead, is ordered individually (see RBPLACE- 
MENT PARTS for the part number). ‘Bvo split beads are 
required to form one complete bead. 
2.8 Tl spans are terminated on telephone company 
RJ4gC modular jacks (or on RI-type blocks that are then 
cross-connected to modular jack assemblies), as re- quired by FCC regulations. Four-pair, non-reversing, 
mod-to-mod line cord is used to connect each Tl span 
directly to the Tl jack on the corresponding Tl Card. 
(Or, to use the optional DB15 connector instead, see 
page 3-21.) 
2.9 It is recommended that gas discharge tubes with 
silicon avalanche suppressors be installed on all non-T1 
trunks for lightning protection. (For Tl spans, the CSU 
itself provides the lightning protection.) Also, in areas 
with frequent occurrences of lightning, it is recom- 
mended that the cable between the telephone company 
termination and the gas discharge tubes be at least 75 
feet long (the cable may be coiled up if desired).

3. EQUIPMENT CABINET 
A. MAIN EQUIPMENT CABINET 
DESCRIFTION 
3.1 The main 416fg32 equipment cabinet is com- 
prised of three major sections: the computer complex, 
the telecommunications complex, and the system power 
supply. The top half of the main cabinet houses the com- 
puter complex (front) and the system power supply 
(back), while the bottom half of the main cabinet houses 
the telecommunications complex. For drawings of the 
main equipment cabinet, see Figures 2-3 and 2-4 on 
pages 2-39 and 2-40. 
3.2 The dimensions of the main equipment cabinet are 
as follows: 
Height 40.0 in. (101.6 cm.) 
Width 32.0 in. (81.3 cm.) 
Depth 23.0 in. (58.4 cm.) 
Weight 
- Empty 170 lbs. (76.5 kg.) 
- Loaded 230 lbs. (103.5 kg.) 
33 The computer complex in the main equipment 
cabinet consists of the following items: IBM AT-corn- 
patible motherboard (called the PC Motherboard), hard 
disk drive, floppy disk drive, 68ooO Co-processor 
(Pro68) Card (or the new expanded Pro6gE Card), High- 
Level Data Link Control (HDLC) Card, Disk Controller 
Card, Monitor Card, and Modem Card. 
3.4 The telecommunications complex in the main 
equipment cabinet contains a 27-slot cardfile assembly 
and the telecommunication cards, including: Telecom 
Motherboard, Matrix Card (MXC), Tl Cards (TICS), 
E&M Cards (EMCs), Loop/Ground Start Cards (LGCs), 
Loop Start Cards (LSCs), Digital Keyset Cards 
(DKSCS), Keyset Cards (KSCs or KSC-Ds), Single- 
Line Cards (SLCs), and Inward Dialing Cards @DC.@. 
B. EXPANSION CABINET DESCRIPTION 
35 The 4161832 expansion cabinet is essentially the 
same as the telecommunications complex in the main 
equipment cabinet. The expansion cabinet also houses a 
27-slot cardfile assembly and the various telecommuni- 
cation cards, including the Expansion Card (EXP). The 
expansion cabinet is installed directly underneath the 
main equipment cabinet. 
3.6 The dimensions of a fully expanded equipment 
cabinet are as follows: Height 64.0 in. (162.6 cm.) -->. 
 
Width 32.0 in. (81.3 an.) 3 
Depth 23.0 in. (58.4 cm.) 
Weight 
- Empty 246 lbs. (123 kg.) 
- Loaded 366 lbs. (165 kg.) 
C. FUNCTIONALDESCBIPTION 
3.7 Together, the computer complex, the main tele- 
communications complex, and the expansion telecom- 
munications complex (if installed) perform the 
switching activities for the system; detect incoming 
calls; process data-controlled features; control the inter- 
action of station instruments, trunks, and intercom calls; 
etc. 
3.8 The system is a microprocessor-controlled, pulse 
code modulation @CM), time-division multiplex 
(TDM) system. Memory includes 1 megabyte (MB) 
random access memory (RAM) on the PC Motherboard 
and up to 4MB RAM on the Pro68/ Pro68E Card. In ad- 
dition, each keyset contains a microprocessor that com- 
municates with the computer complex via a Keyset Card 
and the Matrix Card (or the Expansion Card). 
3.9 When added to the main equipment cabinet, the 
expansion circuitry and software combine to produce an 
“integrated switching matrix” of 512 time slots (16 
PCM highways [buses] 
x 32 time slots). Of the 512 
time slots, 32 are reserved for conferencing and 16 are 
reserved for lYfMF decoders. If additional M’MF de- 
coders are installed (up to 14), additional time slots are 
also reserved. This leaves between 450 and 464 time 
slots available for voice channels. (For a diagram of the 
system voice channel allocation, refer to Figure 2-l on 
page 2-8.) 
3.10 In the main quipment cabinet, there are 208 to 
216 non-blocking voice channels available (depending 
on the number of additional MMF decoders installed 
on the Matrix Card). 
3.11 In the epamion cabinet, there are 242 to 248 
non-blocking voice channels available (depending on 
the number of additional DTMF decoders installed on 
the Expansion Card). 
3.12 Therefore, the total number of non-blocking 
voice channels available on an expanded system ranges 
from 450 to 464. 
3.13 Whenever there is a change in the system’s cir- 
cuit card configuration, all equipped cards are assigned 
to one of the PCM highways (also called buses). The in- 
dividual circuits on each card may use only those voice 
channels available on the assigned PCM highway. The 
software automatically distributes the cards to make the 
best possible use of the available voice channels.

I 
3.14 If there is a large number of cards installed in a 
single cabinet, two or more cards may be assigned to the 
same PCM highway. The voice channels on each PCM 
highway are then allocated to the assigned cards for out- 
side calls, intercom calls, and pages on a first-come, 
first-served basis. Since each two-way conversation re- 
quires two voice channels, the maximum number of 
simultaneous two-way conversations available on an 
expanded system ranges from 225 to 232. 
3.15 If, on a single PCM highway, there are more ports 
equipped than there are voice channels, there is a remote 
possibility that all the voice channels could be in use at 
one time (see Figure 2-l on page 2-8). If this happens, 
a user attempting to place a call or page hears reorder 
tones and must try again (the system also generates an 
error message to indicate that no voice channels were 
available). Generally, a voice channel will be available 
on the second attempt. 
NOTE: It is possible to equip more ports than there are 
available voice channels, especially when installing a 
number of Tl spans, single-line sets, digital keysets, or 
8-line keysets installed two to a circuit. (In fact, the pro- 
grammer can equip up to 416 ports on a standard-size 
system and up to 832 ports on an expanded system.) For 
total non-blocking applications, it is necessary to limit 
the number of circuit cards installed in each cabinet. 
Also, whenever possible, all circuit cards (especially Tl 
Cards) should be evenly distributed between the two 
cabinets. For example, if four Tl Cards are to be in- 
stalled in an expanded system, put two cards in the main 
equipment cabinet and two cards in the expansion cabi- 
net. (See PROGRAMMIN G, page 5-174, for informa- 
tion on designating certain circuit cards as non-blocking 
and generating voice channel allocation data for traffic 
analysis.) 
3.16 As many as nine external paging ports can be 
used for connecting external paging speaker equipment. 
Each external paging port requires an available SLC, 
LGC, or LX circuit. 
NOTE: When installing external paging equipment on 
an LGC or LSC circuit, use a paging amplifier that pro- 
vides talk battery. When installing external paging 
equipment on an SLC circuit, use a paging amplifier that 
DOES NOT provide talk battery. 3.17 The 416/832 System has two music channels. If 
desired, two different music sources (port 1 and port 2) 
may be connected to the Matrix Card. By entering a fea- 
ture code, individual keyset users can choose to listen to 
background music from either of the two music sources. 
Internal users will also hear music from the selected 
source when on hold and when camped on. For outside 
callers, the source for the Music-On-Hold feature is as- 
.sigued on a trunk groupby-trunk group basis. 
3.18 In the main telecommunications complex, the 
slot on the far right (27th slot) is reserved for the Matrix 
Card. Likewise, the slot on the far right (54th slot) of the 
expansion cabinet is reserved for the Expansion Card. 
After that, any station or trunk card may be placed in any 
of the remaining 52 slots. 
NOTE: Information on the type of card installed in each 
telecommunication card slot must be entered through 
database programming. See PROGRAMMING, page 
5-174. 
3.19 The system status panel is located in the upper- 
left comer of the front of the main equipment cabinet. 
The panel has LED indicators to show high power sup 
ply temperature (POWER ALARM), major system 
alarms (MAIOR ALARM), minor system alarms (MI- 
NOR ALARM), main processor operation (CPU AC- 
TIVE), and hard disk drive activity (DISK ACTIVE). 
Refer to the TROUBLESHGGTING section of this 
manual for detailed LED information. 
3.20 The peripheral connector panel is located in the 
upper-left comer of the back of the main equipment cab- 
inet. (For a drawing, see Figure 3-27 on page 3-44.)The 
panel can be used for connecting a programming moni- 
tor, progr amming keyboard, and SMDR/SMDA output 
devices to the system (see page 2-36 for requirements). 
3.21 The Telecom Motherboard power cable, which 
comes pre-routed in the main equipment cabinet, is used 
to connect the main system power supply to the main 
Telecom Motherboard. Likewise, the expansion power 
cable is used to connect the expansion power supply 
chassis to the expansion Telecom Motherboard. 
3.22 If an expansion cabinet is installed, the EXP-to- 
MXC data cable is used to permit communication 
between the expansion cabinet and the telecommunica- 
tions complex in the main equipment cabinet. The ex- 
pansion cabinet is shipped with one end of the cable 
already attached to the Expansion Card slot on the ex- 
pansion Telecom Motherboard. The other end of the 
cable is then attached to the Matrix Card slot on the main 
Telecom Motherboard.

Card, and one Inward Dialing Card to the same PCM highway. If all three cards are designated as 
“blocking” in database programming, the 48 circuits will vie for the 32 voice channels on a first- 
come, first-served basis. If, however, the Tl Card is designated as “non-blocking,” the system will 
rebalance the cards so that the Tl Card is assigned to a highway that has no more than 32 equipped 
ports. (Refer to PROG RAMMING, page 5-174, for information on designating certain circuit cards 
as non-blocking and generating voice channel allocation data for traffic analysis.)

NOTEz It is recommended that the maximum operating 
temperature (as listed above) never be exceeded. There- 
fore, when installing the equipment cabinet, expansion cabinet, and station instruments, allow a sufficient mar- 
gin for error in case of air conditioning failure, routine 
mechanical maintenance, plant shutdown, etc. As a gen- 
eral guideline, if the conditions are suitable for 05ce 
personnel, they are also suitable for all equipment and 
station instrument operation. A properly controlled en- 
vironment will help to extend the operating life of the 
equipment. 
3.24 While in operation, a fully loaded main equip 
ment cabinet generates approximately 1950 British 
Thermal Units (BTUs) of heat per hour. A fully loaded 
expanded system generates approximately 3200 BTUs. 
The maximum amount of heat generated per individual 
station instrument is 6.8 BTUs per hour. 
NOTE: This information is provided so that any cooling 
needed to meet the proper environmental conditions (as 
listed in the chart) can be calculated.

E. SYSTEM POWER SUF’PLIES 
3.25 The main system power supply, which is located 
in the top half of the back side of the main equipment 
cabinet, is installed to provide power to the computer 
complex, the main telecommunications complex, and to 
all associated stations. The expansion power supply, 
which is installed next to the main power supply, is used 
to provide power to the cards and associated station in- 
struments in the expansion cabinet. Bach power supply 
is comprised of a metal chassis with various modules in- 
stalled. 
3.26 The power supply(s) musl have an isolated, dedi- 
cated, 10%12!5VAC, 3OA, 57-63H2, single-phase com- 
mercial power source (for more details, refer to the first 
NOTE on page 3-4 in INSTALLATION). Also, since 
the system AC power cable is terminated on a NBMA 
W-30 twist-lock plug, a compatible AC receptacle 
(w-30R) is needed. 
Main Power Supply Chassis 
3.27 All muin power supplies must be equipped with 
two Quad Modules, one Master 30V Module, one -48V 
Module, and one Ring Generator Module. The first 
Quad Module supplies power (+5V, -5V, +12V, and 
-12V) to the computer complex, while the second Quad 
Module supplies power to the telecommunications com- 
plex. Depending on the number and type of keysets in- 
stalled, one or two Slave 30V Modules may also be 
needed, as outlined in the following paragraph. (Refer to 
RBPLACBMBNT PARTS for the part numbers.) 
3.28 Based on the number of 8-line IMX AIM keysets 
and other-type keysets installed, the following chart can 
be used to determine the number of Slave 30V Modules 
needed in the main power supply chassis. (The program- 
ming System Configuration window will also display a 
message if additional modules are needed.) 
3.29 Located on the front side of the main power sup 
ply chassis are the ON/OFF power switch (which also

quired. 
If y > 8, but < 16, one Slave 30V Module is 
also required. 
lf y > 16, but < 24, two Slave 30V Modules 
are also required. 
If y > 24, the maximum system capacity for 
keysets in a single cabinet is being exceeded. 
. acts as a 20A breaker), a 30A fuse that isolates the AC 
power source from the system, and all of the umnectors 
for the various power cables. 
3.30 Located on the back side of the main power sup 
ply chassis are the AC power cable (and its termination 
strip and strain relief clamp), two auxiliary AC recep 
tacles (for connecting items such as a programminff 
monitor, a printer, etc.), a 1OA fuse for the auxiliary re- 
ceptacles, -an -expansion power supply receptacle (for 
connecting the expansion power supply chassis, if 
used), a 15A fuse for the expansion receptacle, and a 
grounding lug to connect the equipment cabinet to an 
earth ground. 
Expansion Power Supply Chassis 
331 
All expansion power supplies must be equipped 
with one Quad Module and one Master 30V Module. If 
any SLCs, ID& LGCs, 
or EMUS are used in the expan- 
sion cabinet, one -48V Module must also be installed. 
-rs ;“Cs, KSC-Ds, LSCs, and TlCs do not use 1 
. 
3.32 Based on the number of 8-line IMX AIM keysets 
and other-type keysets installed in the expansion cabi- 
net, the chart following paragraph 3.28 can be used to 
determine the number of Slave 30V Modules needed in 
the expansion power supply chassis. (The programming 
System Configuration window will also display a mes- 
sage if additional modules are needed.) 
3.33 Located on the front side of the expansion power 
supply chassis are the ON/Ol?P power switch, a 15A 
fuse that isolates the AC power source from the system, 
and all of the connectors for the various power cables. 
NOTE: Since the fuse on the main power supply chassis 
also protects the expansion power supply, newer-ver- 
sion expansion power supply chassis are not equipped 
with a fuse. 
3.34 Located on the back side of the expansion power 
supply chassis is the AC power cable, which plugs into 
the AC expansion receptacle on the back side of the 
main power supply chassis. 
3.35 The expansion power supply can be turned on 
and off independent of the main power supply. Howev- 
er, when the entire system is to be powered down, first 
“park the heads” if using a hard disk drive that does not 
have self-parking heads (as outlined on page 3-154), 
then turn off the main power supply before turning off 
the expansion power supply. This sequence allows the 
hard disk drive to shut down properly; the reverse does 
not allow proper shutdown and may damage the hard 
disk drive. When bringing the system back up, turn on 
the main power supply first and then turn on the expan- 
sion power supply. The system download will return the 
hard disk drive to normal operation.

Power Supply Modules 
3.36 
Currently, there are three versions of power sup 
ply modules used on the 416/832 System: (A) part num- 
bers 440.0102-0106, (B) part numbers 440.0118- 0122, 
and (C) 
part numbers 440.0112-0115. (Refer to RE 
PLACEMENT PARTS for a complete list of the part 
numbers.) 
3.37 Version A and B power supply modules are com- 
patible with each other, and they use the same chassis. 
However, due to numerous design enhancements, ver- 
sion C modules and chassis are not compatible with ver- 
sions A and B. Either use all version A and B power 
supply modules and chassis, or use all version C mod- 
ules and chassis. Do not mix the two types. 
3.38 The version A Ring Generator Module has a 3 
amp fuse, while all other version A power supply mod- 
ules have 6 amp fuses. Maximum power outputs for 
each version A module are shown below.

maximum power outputs. Also, there is only one version C 30V Module, which can be used as either a master or a 
slave. 
NOTE: For easier power supply module removal, each 
version C power supply chassis is shipped with an ex- 
tractor tool attached to the inside of the back cover. The 
extractor tool may be used with version B and C mod- 
ules only. 
Special Tl Card Requirements 
3.40 
When using version B or C Quad Modules, the 
system allows nine Tl Cards in the main equipment cab- 
inet and nine Tl Cards in the expansion cabinet, for a 
system maximum of 18 Tl Cards. However, when using 
a version A Quad Mnfule, there can be only four Tl 
Cards installed in the associated cabinet and still have 
all other card slots filled. If, while using a Version A 
Quad Module, more than four Tl Cards are installed in a 
single cabinet, there must be two empty card slots in that 
cabinet for each Tl Card over four. For example, if six 
Tl Cards are installed in a cabinet using a version A 
Quad Module, there must be four empty card slots in that 
cabinet (two empty slots for each number over four). 
Voltage Surge and Spike Protection 
3.41 To reduce the effects of AC voltage surges and 
spikes that may cause system malfunctions, false 
logic, 
and/or damage to the electronic components, a surge/ 
spike protector is provided. (Refer to REPLACEMENT 
PARIS for the part number.) Its specifications are: 
0 Clamp voltage transients at 300VDC within 5 nano- 
seconds when exposed to waveforms as described in 
the ANSI/IEEE Standard (X2.41-1980 (IEEE 587). 
l Reduces RFI/EMI noise by at least 20dB at frequen- 
cies between 5kHz and 3OMHx. 
l Designed to interface with the power supply’s 
NEMA W-30 twist-lock plug and the L5-30R (or 
compatible) AC receptacle. 
Battery Back-Up 
3.42 To provide back-up power in the event of a power 
failure or brownout condition, the main and expansion 
power supplies can have optional battery back-up using 
customer-provided uninterruptable power supply (HPS) 
units or standby power supply (SPS) units. Refer to page 
2-38 for more information.

F. COMPUTER COMPLEX PC Motherboard 
NOTICE 
Personal computer (PC) technology is continually 
evolving. As it does, the 416/832 System will con- 
tinue to incorporate important design enhance- 
ments. Thus, depending on the actual version of 
equipment that is shipped, the following specifica- 
tions could vary somewhat. If revised information is 
included with the equipment, refer to it instead. 3.48 The IBM AT-compatible PC Motherboard is the 
main computing device of the computer complex. It 
controls the majority of tasks performed by the 416/832 
System. 
3.49 Currently, there are five versions of PC Mother- 1 
boards used on the 416/832 System: PCC (PC Calc), 
SUNTAC, VLSI, Ml(IC, and the new M396F. The cards 
can usually be identified by the label on several of the m 
processor chips. 
3.43 The computer drives and cards are installed in 
the front of the top half of the main equipment cabinet. . 
The drives and cards are:

Hard Disk Drive 
Floppy Disk Drive 
F’C Motherboard 
68ooocb-Rocesso r (Pro68) Card (or Pro68E Card) 
Disk Controller Card 
High-Level Data Iink Control (HDLC) Card

NOTE: The SUNTAC PC Motherboard cannot be used 
with the new IDE-type Disk Controller Card. And, the 
VLSI, MXIC, and M396F PC Motherboards can only be 
used with HDLC Cards that have been modified and la- m 
beled with ECN-2279 or stamped with artwork number 
826.3806-1, -2, or higher.

3.44 Descriptions of the computer drives and cards are 
given in the following paragraphs. Drawings of each are 
located in the INSTALLHION section. 3.50 There is a 5-pin DIN connector on the bottom 
edge of the card for comtecting a cable to the internal 
side of the peripheral connector panel on the back of the 
equipment cabinet, which in turn is connected to a pro- 
gramming keyboard. The keyboard must be an IBM AI’- 
compatible keyboard (an XT-compatible keyboard 
cannot be used, unless it is equipped with an XT/m 
selector switch). 
68000 Co-Processor (P1-068) Card 
Only the items described in the following para- 
Hard Disk Drive 
Page 2-12 3.51 The Pro68 Card or the new “expanded” Pro68 
Card, called the Pro68E Card, controls the call process- 
ing functions of the 416l832 System. The Ro68f Ro68E 
Card is equipped with a Motorola MC68000 l&-bit 
microprocessor. 
3.45 The hard disk drive is the main storage device for 
the operating system software, the 416/832 System soft- 
ware, the database, and the history files. 
3.46 Currently, there are two types of hard disk drives 
used on the 4161832 System: Sy4-inch MFM-type 
(Mini-Scribe 8425 or Seagate ST-225), and the new 
3M-inch IDE-type (Quantum Pro-Drive 4Om, Conner 
m CITKKl, Conner CP341, or Seagate ST312OA). These 
two hard disk drive types, along with their associated 
Disk Controller Cards and hard disk-to-controller inter- 
face cables, are not compatible. Either use all IDE-type 
equipment, or use all MIW-type equipment. Do notmi* 
the two types. 3.52 If the Ro68 Card is used, it comes with 1 mega- 
byte (MB) RAM. For standard-size systems (main 
equipment cabinet only), the Pro68 Card must be 
equipped with a 512k Memory Card. For large-size sys- 
tems (expansion cabinet installed), the Ro68 Card must 
be equipped with a 3MB Memory Card. (See RE- 
PLACEMENT PARTS for the part numbers.) 
3.53 If the Ro68E Card is used, it comes with 2MB 
RAM, which is enough memory for a standard-size sys- 
tem. Zf an qansion cabinet is installed, two 1MB 
single in-line memory modules (SIMMs) must be 
attached to the Ro68E Card to provide an additional 
2MB RAM. (Refer to REPLACEMENT PARTS for the 
part number.) 
Floppy Disk Drive 
3.47 The floppy disk drive is used to initially load the 
4161832 System software onto the hard disk drive. 
Thereafter, it is used for saving and restoring the system 
database and for performing software updates. 3.54 There are two DB9 connectors (g-pin, subminia- 
ture “D”, female connectors) on the bottom edge of the 
Ro68/Pro68E Card for connecting cables to the internal 
side of the peripheral connector panel on the back of the 
equipment cabinet, which in turn connects to the option- 
al Sh4DR/SMDA output devices. For more information, 
refer to page 2-36.
