MultiModemISDN User Guide

Command: &Fn

Function: Load Quick Setup Profile

Values: n = 0–4

Default: &F0

Description: For quick setup, the TA includes six Quick Setup Profiles, each contains configuration parameters for a specific type of port operation. To load a Quick Setup Profile into active memory, use &Fn, where n is the profile number to load. You then can customize the profile and store it using the &W command, so it loads automatically on power-up or reset. These profiles are stored in permanent memory and are not user configurable. (Appendix B.) &F0 Profile 0 — Modem-like operation (default)

&F1 Profile 1 — V.110 async operation* &F2 Profile 2 — V.120 async operation &F3 Profile 3 — X.75 async operation &F4 Profile 4 — MLPPP async operation

*The MTA128ST-USB is manufactured in two builds. To determine the build of your terminal adapter (TA), issue the ATI2 command in a terminal window. If the TA responds to the command with MTA128ST- USB, then it supports V.110. If your TA resonds to the ATI2 command with MTA128ST-USB-RC, V.110 support is not available. The MTA128ST-USB-RC will respond to the &F1 command with an ERROR..

Command:	&Jn
Function:	Automatic Channel Bundling
Values:	n = 0 or 1
Default:	n/a

Description:&J1 causes the TA to dial the number given in the dial string again to set up

	a bundled PPP connection (also known as MultiLink PPP). Only works with
	the PPP/ML-PPP protocol (!Z=9). &J0 will not dial the given number again
	and it will not interfere with the given dial string meaning that if there are two
	numbers in the dial string (like ATD5551000&5553000) the TA will dial both
	of those numbers. &J0 does not disable the dialing of a second number if a
	second number is given in the dial string.
	n=0	disables automatic channel bundling
	n=1	enables automatic channel bundling
Command: &Rn
Function:	CTS Control
Values:	n = 0, 1, or 2
Default:	&R1 (CTS forced high)
Description:Allows you control the state of the CTS (Clear to Send) signal on the
	RS232E/V.24 interface. Normally the CTS signal follows the state of the RTS
	signal when the MTA128ST-USB is online.
	&R0 CTS acts normally; i.e., it follows RTS
	&R1 CTS is forced high, but still provides online flow control
	&R2 CTS is forced high, but it drops on disconnect for the period of time
	set by S10. CTS still provides flow control when the TA is online.
Command: &Sn
Function:	DSR Control
Values:	n = 0, 1, or 2
Default:	&S0 (DSR high)
