General Tab

The General Tab lets you set Protocol, DTE, and POTS parameters. 

Protocol
Sets the protocol type: PPP Async-Sync, Async Bonding, V120, 
Fallback.

The Express 3000 communicates with many different types of tele-
communications equipment including other Express 3000 units, 
other ISDN terminal adapters, and PPP-compatible devices. Com-
munication between such devices requires various rate adaption 
protocols supporting various bit rates and RS-232 connector set-
tings (protocol type).

PPP Mode
Selects the PPP mode the Express 3000 uses: Point-to-Point (PPP) 
Async-to-Sync, Multilink PPP (MP), or PPP with Compression.

Enable Bandwidth on Demand
Uses the thresholds defined in the 

 tab to bring up and 

down multilink channels, when this feature is enabled.

Disable BACP
Controls the negotiation of Bandwidth Allocation Control Proto-
col (BACP). BACP allows the client and server to exchange phone 
number information and bring up and down channels, as needed.  
Check 

 to use this feature. 

DTR Options

Disregards the state of the data terminal ready 
(DTR) signal on the EIA-232.

Forces the unit into the AT command processor 
mode when DTR is not asserted. To return on-
line, DTR must be asserted and the 

 com-

mand must be issued.

Answers incoming calls only if DTR is asserted.

Forces an end to the current call when DTR is no 
longer asserted.
