Command: $MBn
Function:

V.110 Network Rate*

Values:

n = 600, 1200, 2400, 4800, 9600, 19200, 38400

Default:

$MB38400

Description: If S77=1, then the network rate of the V.110 connection will match that of $MB (S76).

If a V.110 call is received and S77=1, then the incoming V.110 network rate must match
$MB (S76) or the connection will fail. If S77=2 and a V.110 call is originated, then the
network rate will match that of $MB (S76). If S77=2 and a V.110 call is received, then the
setting of $MB (S76) will have no effect on the network rate of that call (see S77 for a
description for this case). The value of $MB will change if S76 is changed and the value
of S76 will change if $MB is changed.

* 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.
