SERIES II INTELLIGENT DATA/FAX MODEMS

Switch #10

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

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

The Series II 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/Series II Responses (Asynchronous Mode/Leased line/Dial-Up)

In Asynchronous mode, you can set the Series II Modem to respond with Result Codes according to the “Series II" 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 Series II Result Codes), and is explained further in section 5.3 of this manual.

“AT" Responses (&Q1)	=	Switch #11 UP
“Series II" 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
