Switch #10

Leased Line/Dial-Up Operation -- "DDD"

(Asynchronous/Synchronous Mode/Leased Line/Dial-Up)

The modem operates in either leased-line or dial-up modes. This switch controls leased-line/dial-up

operation. Place DIP-Switch #10 in the UP position for Dial-Up operation. Place DIP-Switch #10 in

the DOWN position for Leased-Line operation

Dial-Up Operation = Switch #10 UP

Leased Line Operation = Switch #10 DOWN

Factory Default Setting = UP

Switch #11

"AT" Responses/Multi-Tech Responses

(Asynchronous Mode/Leased line/Dial-Up)

In Asynchronous mode, you can set the modem to respond with Result Codes according to the

"Multi-Tech

" command response set (Switch #11 in the DOWN position), or to

"AT"

command

response set (Switch #11 in the UP position). The

&Q

command performs the same function

(choosing AT or Multi-Tech Result Codes), and is explained further in Section 5.3 of this manual.

"AT"

Responses (

&Q1

) = Switch #11 UP

"Multi-Tech"

Responses (

&Q0

= Switch #11 DOWN

Factory Default Setting = DOWN

Switch #11

Internal/External Clocking

(Synchronous Mode/Leased Line/Dial-Up)

In Synchronous mode, the transmit clock can be supplied by the DTE on pin 24 of the RS-232C/V.24

interface by placing DIP-Switch #11 UP. Place DIP-Switch #11 in the DOWN position to enable DCE

to control clocking (internal clock via pins 15 and 17 of the RS-232/V.24 interface).

External Clock (pin 24) = Switch #11 UP

Internal Clock (pins 15/17) = Switch #11 DOWN

Factory Default Setting = DOWN

Switch #12

Asynchronous/Synchronous Operation -- "Sync"

(Asynchronous/Synchronous Mode/Leased Line/Dial-Up)

The modem can operate in either Asynchronous mode or Synchronous mode. In Synchronous mode,

start and stop bits are eliminated. The modem's internal clock circuits on the RS-232C/V.24 pins 15

and 17 are activated. The modem's Command mode is not accessible in Synchronous mode. This

switch is a means to alternate and to access either mode. In Synchronous mode, you may want to

set the RTS forcing and CTS forcing DIP-Switches so that both of signals act normally (not forced

on).

Synchronous Operation = Switch #12 UP

Asynchronous Operation = Switch #12 DOWN

Factory Default Setting = DOWN
