FCC REGULATIONS
Instructions to comply with FCC Regulations:
System Registration: In some states, the tariff laws
concerning the connection of multi-telephone system
require that the FCC number be reported to the tele-
phone company to signify the type of installation.
The Protegé system has two FCC regulation numbers
for each KSU type corresponding with two modes of
operation. Before contacting the telephone company
to order telephone lines, determine the proper FCC
number from the label on the KSU. The two opera-
tion modes are:
"MF" - Fully protected multi-function system,
"KF" - Fully protected key system.
The Protegé 616 System FCC Registration Num-
bers are:
MF = FTZTAI-35688-MF-E
KF = FTZTAI-35689-KF-E
Only report the "KF" number if lines can only be
accessed singly by pressing line keys on the keysets.
If any type of pooled access to Central Office lines is
available (including LCR, line routes, or even the
capability of dialing 9 to search for a free outside
line) the "MF" number should be reported.
Notification Requirements: The Protegé 616 equip-
ment is registered with the Federal Communications
Commission under Part 68 Rules and Regulations for
direct connection to the telephone network. Read
and follow the instructions below to comply with
FCC regulations.
Terminal Equipment or Protective Circuitry: This
equipment complies with Part 68 of the FCC Rules
and Regulations. The information containing the
FCC Registration number and ringer equivalence
number (REN) is located on the label of this equip-
ment. If requested, this information must be pro-
vided to the telephone company.
The following information must be provided to
the telephone company, if requested.
USOC = RJ25C
Service Order Code = 9.0F
Facility Interface Code = O2LS2
REN: 1.5B
The REN is used to determine the quantity of
devices that may be connected to the telephone line.
Excessive RENs on the telephone line may result in
the devices not ringing in response to an incoming
call. In most, but not all areas, the sum of the RENs
should not exceed five (5.0). To be certain of the num-
ber of devices that may be connected to the line, as
determined by the total RENs, contact the telephone
company to determine the maximum REN for the
area.
Notify the telephone company upon final discon-
nect of such equipment or circuitry from the particu-
lar line(s).
Systems Assembled with Individually Registered
Terminal Equipment or Protective Circuitry: Notify
the telephone company before connecting any
system assembled with individually registered ter-
minal equipment or protective circuitry to the tele-
phone network. Supply the following information
for each line:
1. Any information required for compatible
operation of the equipment with telephone
company communications facilities.
2. The FCC Registration Numbers for all equip-
ment dedicated to the line.
3. The largest ringer equivalence that will be pre-
sented to the line.
4. A list of FCC Registration Numbers for all

test emergency numbers in off-peak hours
during the early morning or late evening.
6. This equipment is capable of providing access
to interstate operator services through the use
of equal access codes. Modifications by aggre-
gators to alter these capabilities is a violation
of the Telephone Operator Consumer Services
Improvement Act of 1990 and Part 68 of the

2. Cabling and MDF
Cabling and wiring used for the 616 system should
meet or exceed the following specifications.
2.1 Wiring Overview
Connections between CO lines, station instruments,
external equipment and the 616 board are made at
the Main Distribution Frame (MDF). See Figure 2-1.
For standard telephony wiring, the MDF usually
consists of a 3/4" wood backboard mounted on a
wall in the utility closet where the system switching
components will be installed. One standard 66M1-50
type terminal block is attached to the backboard for
the actual wire connections.
2.2 Station Wiring
Protegé station equipment requires unshielded,
twisted pair (UTP) 24-gauge cable. Each station uses
only one wire pair. For convenience in terminating,
however, two pair is recommended. The second pair
can be used as a backup connection if the first pair is
damaged. All unused pairs should be grounded at
the MDF.
The station cable runs must not exceed the lengths
listed in Table 2-2: Maximum Loop Distance and
Cable Resistance.
2.3 Interface Cable
The Protegé 616 KSU and 3x8 expansion board each
require one 25-pair amphenol-type (male-ended)
interface cable for terminating the CO lines and digi-
tal extensions. This cable may be purchased in a 2-3
foot length with a 66M1-50 block already terminated.
Alternatively, the cable can be prepared on site.
Instructions on preparing this cable are not included
in this manual.
2.4 Grounding Cables
Sprint Products Group highly recommends ground-
ing all unused cable pairs at the MDF to an earth
ground point.
2.5 Station Modular Jacks
Terminate station cable runs on modular jacks
mounted near where the station instrument will be
placed. Each station requires a 1-pair connection.
2.6 Terminal Block
Use one 66M1-50 style terminal block to terminate
the KSU interface cable for station and line connec-
tions. Terminate the KSU interface cable on the right
side of the block. Terminate the station and line
cables on the left side of the block. Each line and sta-
tion cable requires a two-wire connection. Use bridg-
ing clips to complete the connection after the
terminal block has been punched down.
Important: Make sure that the system power is off while
making terminal block connections. Shorting punch block
terminals together can damage the KSU.
2.7 Phono Jack Connections
The KSU has two mono, 1/8" mini-phono jacks.
These can be used for external music source and
external paging. The music source's optimum input
level is 0 dB, 600 ohm input impedance. The external
paging source's optimum output level is 0 dB, 600
ohm output impedance.

3. Equipment Cabinet
3.1 Protegé 616 KSU
The 616 Key Service Unit (KSU) houses the main
Printed Circuit Board and Central Control Board.
The main printed circuit board provides interface for
three loop-start CO lines and eight key telephones.
The Central Control Board performs all the control
functions including digital voice and data communi-
cations.
The design of the KSU includes a conductive paint
on the inside cover that acts as a ground path to the
ground lug connection on the side of the KSU.
Protection from over-current is provided by a fuse,
which is rated 5A, in the power transformer.
3.2 Protegé 616 Power Supply
A power adapter is included with the KSU. It pro-
vides electrical power to the internal components of
the KSU and to all station instruments except analog
adapters. Power is applied or removed from the unit
by plugging and unplugging the AC adapter from
the AC outlet. Connect the adapter cord to the KSU
before the AC adapter is plugged into the AC outlet.

4.2 Central Control Board
This board contains all circuitry to control the fully
equipped KSU. There is an internal connector
between the main PCB and the Central Control
Board. The Central Control Board contains:
• An 8088-compatible 16-bit microprocessor
• 512 Kbyte ROM chip containing system software
• 128 Kbyte CMOS RAM with battery backup
• Interrupt controller
• Time slot interchange circuit
• Digital conference circuit
• System heartbeat indicating red LED
• System timing circuit and PCM frame timing circuit
• CPU/RAM reset switch for initialization
4.3 Auxiliary Board

nal input and output devices (music source and pag-
ing equipment).
5. Optional System
Components
5.1 3x8 Expansion Board
One 3x8 Expansion Board may be installed in the 3x8
KSU to expand the system to a maximum capacity of
6 lines and 16 digital extensions.
5.2 Analog Adapter
Analog Adapters can be connected to any of the digi-
tal station ports.
5.3 Station Instruments
Protegé®616 supports the Business with Display
and Business without Display keysets. Additionally
the 616 system works with single-line phones, fax
machines and voice mail systems that must be con-
nected to the 616 KSU via an analog adapter.
6. Optional Equipment
6.1 Music on Hold/Background Music
Radios, CD players, tape players and other audio
sources can be connected to the external music port
on the KSU. The external source is mono and the
impedance must be 600 ohms to match the input
impedance of the external music port.
Note: Broadcast music sources are subject to copyright
restriction.
6.2 Voice Mail
Commercial voice mail systems can be attached to an
analog adapter port. The interface requirements for a
voice mail system are the same as those for an indus-
try standard single line phone.
6.3 Fax
Commercial fax equipment can be attached to an
analog adapter port. The interface requirements of a
fax system are the same as those for an industry stan-
dard single line phone.
6.4 External Paging
The 616 KSU provides a single paging port. It has an
output impedance of 600 ohms. If an external paging
unit is connected to a Protegé® system, its input
impedance also should be 600 ohms to match.
Matching impedances ensures maximum output
from the pager and noise free operation. The page
port output is 0 dBm.
6.5 Power Failure Transfer
Power failure transfer provides a bypass for outside
line calls during power failure with no backup bat-
teries or after the backup batteries have been
depleted. This is a hardwired feature. The system
automatically switches the first line to an optional
dedicated analog telephone connected to the 66M1-
50 block. During Power Failure Transfer, incoming
calls on line 1 only ring at this analog phone. The
phone also may be used to place outgoing calls for
assistance.
7. Station Instruments
The Business with Display and Business without
Display digital keysets are available for use on the
Protegé 616. These models make the extensive collec-
tion of features easier to use. In addition to the two
keysets, Protegé 616 works with single line phones
and other analog devices such as fax machines,
modems and voice mail systems that must be con-
nected via an analog adapter.
