Test Mode 7

Test Mode 7 is the Switch and LED operational test.

By running

your MultiMux

in

this

test

mode,

you

can

switch

the

eight

&T7

DIP-switches and verify that they work by corresponding LEDs

being lit.

Test Mode 8

Test

Mode

8

is

the Non-Volatile

Memory

test. Its function

is

to

check the proper operation of the MultiMux’s storage of operational

&T8

parameters. This test will overwrite the stored parameters.

Test Mode 9

Test

Mode

9

is

the Watch-Dog Timer test.

This

test

checks

the

MultiMux’s Watch-Dog circuitry. The

function

of

the

circuitry

is

to

&T9

return

the

mux

to

normal operating

mode

if,

for

some

reason,

its

operation becomes erratic.

Test Mode 10

Not used.

Test Mode 11

Test mode 11 is the local channel test which checks the operation

of all channels (cabling,

connection, etc)

by outputting "The

&T11

Quick Brown Fox Jumped Over..." to all channel devices. You

should receive the complete sentence each time an &T11

command is executed.

Test Mode 12

Test mode 12 is the voice/fax loopback test (if the voice/fax

feature

is installed).

When this test is initiated, voice/fax channel

&T12

1 will communicate with voice/fax channel 2 and vice/versa on

the same MultiMux unit.

You will need to configure the local and

remote interface types (FXS,FXO, E&M) that you wish to test on

each voice/fax channel.

Test Mode 13

Test Mode 13 is the local loop test that receives data from a

synchronous

device

and loops that data back to the sync device.

&T13

The MultiMux has to have port B configured as a synchronous

data channel in order

for this test mode to function. To exit the test

mode, you need to reset the MultiMux by entering a ATZ command.

Command Modem Commands

The command modem select and remote access commands are described in this section. The command modem accepts commands at speeds up to 2400 bps. Additional command modem AT commands are provided in Appendix D.

Command	The Command Modem Select command #MA1 sends all
Modem	subsequent commands generated on your supervisory console
Select	to the command modem. The various commands for the
	command modem are AT command set compatible with those
#MA	described in Appendix F. The #MA1 command enables the		command modem.
The #MA0 command disables the command		modem input and hangs up the phone line.
