AC International MTA128ST-USB manual S80

MultiModemISDN User Guide

Default: 2 (use $MB(S76) or Auto Sync on Answer)

Description: The Network Rate for V.110 will be determined by S76 ($MB). If S77=1, then the network rate will be set to that of S76 ($MB) and if the network does not match that of the peer device, then the connection will fail. Properties of S77=1 apply to both received and originated calls. If the TA will be answering a V.110 call, then it can be set to auto-synchronize (S77=2) on the incoming V.110 network rate.

Auto-synchronizing allows the TA to adapt to the client’s network rate without any need for the host to have its network rate predetermined. If S77=2 and a V.110 call is originated, then the network rate will be that of S76 ($MB).

*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.

S-Register:	S80
Function:	Persistent DTR Dialing Delay
Unit:	1 second
Range:	n=1-255 (1-255 seconds)
Default:	5 (5 seconds)

Description: Once DTR is detected as present (active high) and other conditions required for the TA to dial are met, a delay of S80 seconds will occur before stored number 0 is dialed. Some conditions include the TA not being in the @CONFIG menu, not having a data call present at the time, and Persistent DTR Dialing must be enabled. By default the TA will delay for 5 seconds before dialing when all conditions are satisfied.
