The MT5600BR-V92 is designed on a single printed circuit board. This board contains sixteen DIP-
Switches. There is a two-position
"Out of Service" (OOS) toggle switch that extends from the front of the
modem circuit card. There is also a two-position TEST/OOS berg jumper located towards the back and
center of the card.

The sixteen DIP-Switches and berg jumper control various modem options or set default values for the
MT5600BR-V92 Command mode. There is a difference in how several of the switches operate depending
on whether you are in synchronous or asynchronous mode (DIP-Switch #12).
Most communications software packages have installation procedures of their own, which call for certain
modem DIP-Switch settings. If you are using such a package, follow the software's instructions.
DIP-Switch Settings
The vast majority of installations are similar, with the MT5600BR-V92 being used to dial up a remote
installation where the call is automatically answered. The factory default DIP-Switch settings are based
on this assumption. The following is a brief description and summary of the MT5600BR-V92's DIP-Switch
options:
Switch Function Position Effect
#1 DTR Forced/ UP* DTR dependent on interface
DTR from Interface * DOWN DTR forced ON at all times
#2 Flow Control &E4* UP* Hardware flow control
(Async/Dial-Up/Leased Line) DOWN Software flow control
#2 SDLC*/BSC (Sync) UP* SDLC mode
DOWN BSC mode
#3 Result Codes Enabled* UP Q1 Disable Responses
(Async Dial-up) DOWN* Q0 Enable Responses
#3 DbM Transmit -15dB/-11dB* UP Lease Line
(Async/Sync/Leased Line) DOWN* transmits at -11dB
#4 No affect in async
#4 AS/400 Mode Disabled* UP* AS/400 Mode OFF
(Sync Dial-Up/Leased Line) DOWN AS/400 Mode ON
#5 Auto-Answer Enabled* UP* Enable Auto Answer
(Async/Sync/Dial-Up) DOWN Disable Auto Answer
* Factory default setting.
