Several power supplies and connection schemes are available for providing
auxiliary adjunct power when it is required. Refer to theAdjunct Powersection
later in this manual for more information on these power sources.
Data Modules
Data modules provide an interface between the system’s digital switch and Data
Terminal Equipment (DTE) or Data Communications Equipment (DCE). DTE is
defined as a data source or a data link or a combination of both; typical examples
are data terminals and host computers. DCE is equipment that provides the
functions for establishing, maintaining, and terminating a data call; a modem is an
example of DCE.
An interface device between the switch and DTE or DCE is necessary because
the set of data transmission rules and formats—the data protocol—at the switch is
different from the protocol at the DTE or DCE. The digital por ts of the switch
present a DCP or ISDN-BRI interface to all devices connected to them. DCP
suppor ts simultaneous voice and data communications by multiplexing the two
sets of signals into one digital stream. Digital voice terminals and some data
terminals can be connected directly to the switch. But, if a data endpoint has a
different protocol (EIA RS-232C or RS-232D is the most common) than the Speakerphone, S102A

switch, a data module must be inserted to provide compatibility. The data module
provides the two-way data signal conversion and processing required between
different protocols. Figure 2-3 shows a simplified diagram of the components of a
typical data link.
Figure 2-3. Data Link Components
The connection between a data module and a data endpoint must always have a
DCE or DTE interface. If the endpoint is a DCE, the data module must present a
DTE interface to it. If the endpoint is a DTE, then the data module must present a
DCE interface. In general, modules are classified as DCE- or DTE-type according
to the kind of data endpoint to which they are connected.
Data modules are available to match a wide variety of data needs:
nAsynchronous operation at data rates from 0.3-19.2 kbps and even, odd,
mark/space, zero/one or no parity options.
nSynchronous operation at data rates of 0.3, 1.2, 2.4, 4.8, 9.6, 19.2, 56, and
64 kbps.
nHalf- or full-duplex operation and internal or external timing options at the
appropriate data rates.
The following data equipment is available with a DEFINITY G1, G2, and G3, a
DEFINITY ECS, System 75, and System 85:
n7400A Data Module— In DTE mode, works with asynchronous DCE in
the modem pool at data rates of 0.3-19.2 kbps, full-duplex. Supports both
Hayes-compatible and D-lead modems. In DCE mode, the 7400A has
Hayes
®, Keyboard Dial or Answer-Only interface. Also works with
asynchronous DTE where rack mounting is needed. Takes the place of

Data Terminals
A data terminal is a workstation at which data is entered and retrieved; it
communicates through lines, trunks, switches, and data modules with data
endpoints such as computers and other data terminals. Some data terminals
contain built-in voice capabilities similar to digital voice terminals. For detailed
information on buttons, lights, and tones, refer to the general information about
voice terminals at beginning of this section.
The following data terminals are available with System 75, System 85, and
DEFINITY G1 and G2:
nPersonal Terminal 510A (no longer manufactured)(DA)
nPersonal Terminal 510D (no longer manufactured)(DA)
nModel 513 Business Communications Terminal (BCT) (no longer
manufactured)(DA)
nModel 515 BCT (no longer manufactured)(DA)
nModel 610 BCT
nModel 615 MT
The 513 BCT, 610 BCT, and 615 MT, in addition to being optional units of
peripheral equipment, are used in DEFINITY G1 and System 75 as System
Access Terminals (SATs). The SAT is dedicated to system administration and
maintenance and is located in or nearby the equipment room with the DEFINITY
G1 or System 75. This manual does not cover the 513, 610, or 615 as an SAT but
only as peripheral data terminals used for sending and receiving data calls.

Exposed Port Protection
All port packs and terminals require unique protection and grounding
arrangements as defined in the checklists (
System 75 Electrical Protection,
Grounding, and Exposure Checklist
, 555-200-120 andSystem 85 Electrical
Protection, Grounding, and Exposure Checklist
, 555-103-120). These
arrangements provide an adequate barrier to the potentially damaging voltages
and currents inherent in lightning and power surges present in exposed
applications. Moreover, the National Electrical Code requires that an approved
protector be provided on all exposed circuits.
Ports and terminals that utilize facilities that are subject to disturbances from
lightning, ground potential rises (GPR), or possible contact or induction from
electrical power sources or circuits in excess of 300 volts (RMS) to ground are
classified as exposed. Any por ts or terminals served by such exposed facilities
are classified as exposed and require protection at both the por t and terminal
ends. The checklists contain flowchar ts that are beneficial in determining
exposure status and tables to determine the type of protector required.
Out-of-Building Campus Stations
An out-of-building campus station is a telephone or voice terminal that is not
physically located in the same building as the equipment room, but is located on
the same proper ty. Both analog telephones and digital voice terminals can be
used as out-of-building stations.
Carbon block, or equivalent, protection is required at both building entrances for
analog out-of-building stations. Sneak current protection is also required.
Protection can be provided by a 4-type protector or a 3-type protector plus a
separate sneak current protector. The 4-type protector is equipped with a heat coil
for sneak current protection. The 4-type primary protector is the preferred device.

Protection is required at both entrances for digital out-of-building voice terminals.
There are two different types of protectors that can be used to protect digital voice
terminals and digital line circuit packs in an out-of-building environment: the
4C3S-75 Enhanced Protector and the ITW Linx Enhanced Protector.
NOTE:
The 4C3S-75 Enhanced Protector may only be used on Vintage 14 or newer
TN754 Circuit Packs. The 4C3S-75 can be used on all vintages of the
TN754B Circuit Pack. The ITW Linx Enhanced Protector may be used on all
Vintages of the TN754 and TN754B Circuit Packs.
The 4C3S-75 Enhanced Protector is equipped with a heat coil for sneak current
protection and the ITW Linx Enhanced Protector is equipped with replaceable
fuses for sneak current protection.
The maximum range for out-of-building voice terminals is 3,400 feet when using
24 AWG wire and 2,200 feet when using 26 AWG wire. The range can be
extended to 5,000 feet (24 AWG) or 4,000 feet (26 AWG) with the use of a Data
Link Protector (DLP). The DLP is an isolating transformer used to remove
phantom power on the switch side and reintroduce it on the terminal side. When a
DLP is used, the voice terminal must be locally powered by an external power
supply or through the AC power cord provided with some of the 7400 series voice
terminals. The DLP is installed on the equipment side of the protection in both
buildings. In high lightning areas, the DLP may also be installed to provide the
maximum degree of protection and reliability.
