Selectors

1

6:

First

and

last

choices

of

transmission

speed

for

fallback

These

selectors

are

used

to

set

the

MODEM

speed

range.

With

the

first

transmission

speed

choice

specified

by

selectors

1

through

3,

the

equipment

attempts

to

synchronize

the

data

transmission

via

the

MODEM.

If

the

synchronization

fails,

the

equipment

automatically

steps

down

to

the

next

lowest

speed

and

attempts

to

synchronize

the

data

transmission

again.

The

equipment

repeats

this

sequence

while

stepping

down

the

transmission

speed

to

the

last

choice

specified

by

selectors

4

through

6.

If

the

MODEM

always

falls

back

to

a

low

transmission

speed

(e.g.,

4,800

bps),

set

the

first

transmission

speed

choice

to

the

lower

one

(e.g.,

modify

it

from

12,000

bps

to

7,200

bps)

in

order

to

deactivate

the

high-speed

MODEM

function

and

reduce

the

training

time

for

shorter

transmission

time.

Generally,

to

save

the

transmission

time,

set

the

last

transmission

speed

choice

to

a

higher

one.
