Unpacking and Inspection

1.03 Inspect the data modem thoroughly after

delivery. If the data modem has been

damaged in transit, please report it

to

the carrier

and

to

Rixon Inc., Customer Engineering Depart-

ment, at

(301)

622-2121

or TWX 710-825-0071. Make

an

operational check after installation is com·

plete. If necessary, verify that

circuit

card connec-

tors are properly seated by

following

disassembly

and reassembly

instructions

in paragraph 2.02

of

this section. Ensure that the ordered mounting

cable is included

with

the data modem.

C.

ODD

Service

Applications

1.04 The TA201 C DOD

switched

network

applications include manual

or

automatic

answering,

compatibility

with

Automatic

Calling

Units

(ACUs), and

multiple

line

installations.

Typical FCC service applications for the

DOD

Switched Network are listed in Table 2-A. Special

applications for privately owned systems

or

appli·

cations which

do

not require FCC registration are

listed in Table 2-B.

NOTE: This data modem

cannot

be

1.05 Prior

to

installation, the telephone company

must be

notified

of

the intended installa-

tion. The Universal Service Order Code

(USOC)

number for the telephone service jacks are listed

in Table 2-A. One

of

the codes

must

be

specified

for installation by the telephone company. The

FCC.

registration number and ringer equivalence

number (located on label on outside

of

data

modem)

must

also be provided.

NOTE: This data modem

(as

of

the date

of

manufacture) is

compatible

with telephone

company

communications

facilities

with

which

it

was

intended

to operate. However,

if

the

telephone

company

changes

its

communications

facilities,

equipment,

operations,

or

procedures

such

that

this

equipment

is no

longer

compatible, RIXON is

not

responsible

for

the

cost

of

modification

or

replacement

of

the data modem.

1.06 The transmit line level

of

a

TA201

C Data

Modem is determined by

an

internal adjust-

able attenuator and by a resistance connected

across programming pins

18

and

19.

A series

of

different telephone interface cable assemblies

allows the data modem to be applied

to

different

level setting arrangements:

• Adjustable (for applications not requiring

FCC registration) -uses cable

with

jumper

between pins

18

and

19.

Transmit level is

set by internal attenuator.

• Fixed loss loop -uses cable

with

866

ohms resistance between pins

18

and

19.

Transmit level is

-4

dBm maximum.

• Permissive -uses cable

with

9310 ohms

and resistance between pins

18

and

19.

Transmit level maximum is

-9

dBm.

• Programmable -uses cable

with

leads

from pins

18

and

19

to

connect to

resistance

built

into telephone company

supplied interconnection point.

NOTE: When

either

fixed

loss

loop, permis-

sive,

or

programmable level

setting

applica-

tions are used, the data modem

internal

attenuator

must

remain in factory

set

O dBm

position.

Doing

otherwise

adds

additional

attenuation

to

transmitted

signals.

ACCESS

TO

DATA MODEM OPTIONS

2.01

The data modem is equipped

with

a number

of

options

that can be selected at the instal-

lation site

without

test

equipment or

tools

other

than a screwdriver. Option selection is determin-

ed

by the servicing telephone company and

customer. Telephone company selected

options

for private line and

ODD

network applications are

provided in Table

2-D.

User selected

options

for

p_rivat~

line and

DOD

network applications are pro-

vided

in

Table

2-E.

Read

the description

of

each

option before installing; many are interrelated.

A.

Data Modem Disassemblyand Reassembly

2.02

It is necessary to remove data modem

circuit

cards from the desk-top enclosure

to

inspect

or

install options. Use Fig.

2-1

and the

following procedure:

(a)

Use a flat-blade screwdriver

in

access slot

on bottom

of

bezel

to

pry card assembly

from case. Loosen and

disconnect

assembly

from rear housing connector.

R

E

A

D

Never use force while removing assem-

bly from case because damage may

re-

sult. Handle assembly by front panel

and card edges only. Static changes

may damage ICs.

(b)

Slide

card

assembly

from

case

while

gripping front panel. Set card assembly on a

nonconductive surface. Card assembly con-

sists

of

three

circuit

card layers separated by

nylon spacers.

(c)

Options

are

accessible

at card edges

between

circuit

card layers.

Power Requirements

3.02

A standard three-wire

receptacle is required to provide

ac

power

for the data modem. Refer

to

the specifications

table in the Description and Operation section for

the power specifications. This power receptacle

should not be controlled bya switch.

panel. When

an

801

Automatic Calling Unit

(ACU)

is used with the data modem; data modem,

business machine, and

ACU

grounds must all

be

served from the same ac distribution panel.

3.03 To avoid possible errors due to potential

difference between grounds for the data

modem and business machine, the power recep-

tacles for the data modem and business machine

must be served from the same

Telephone Interface Requirements

3.05 The private line version

of

the telephone

interface cable requires a maximum

of

six

conductors, while the switched network version

requires a 15-conductorcable terminated in a con·

nector

to

mate

with

the 565 telephone. Table

of

E.

Data Line Requirements

3.06 To avoid

interference

during

data

transmission,

use

only

individual

data

(telephone) lines and do

not

connect extension

telephones.

To

minimize inductive interference

to

the data signals, data lines should not be carried

in the same cable run

with

cables between data

modems and business machines or

with

lines

connected

to

DC

teletypewriter services. If

this

requirement cannot be met, run data lines in

shielded

(SK)

station wire between the data

modem and cable

distribution

terminal

or

building

entrance. The shield should be terminated on one

end only, perferably the

distribution

terminal end.

TELEPHONE MODIFICATIONS

4.01

In

some applications

it

may be necessary

to

modify

the

multiple

following procedures are

for

modifications

which

are referred

to

in the service application tables

and connection diagrams. Figure

Modification

4.02

When automatic answer is required the data

modem

is

normally optioned for permanent

automatic answer. However, the

multiple

line

telephone can be modified

to

provide auto-answer

inhibit

in single line applications.

4.03

Modify

the 565 or 2565 telephone

as

follows:

(a)

Remove telephone set cover by removing

two slotted screws in front and rear

of

(b)

Disconnect orange-white lead from terminal
