V.110 signaling is a form of ISDN rate adaptation (see figure 29). V.110 is a fixed-frame based rate adaptation
standard that allows lower data rates to be communicated across 64-kbps ISDN.
The following rates are supported: 600, 1200, 2400, 3600, 4800, 7200, 9600, 14400, 19200, 38400, 4800
and 56000. V.110 and its data rate is determined via the bearer capability information element or the lower
layer compatibility information element in the ISDN SETUP message as defined in the Q931 specification
Limitations:
• 56000 only supports PAP and CHAP authentication. All other data rates support text, PAP, or CHAP.
• 56000 only supports a synchronous connection; all other data rates support both synchronous and asyn-
chronous connections.
Note If V.110 is disabled and a V.110 call comes in, the call will be termi-
nated and V110 disabled will be displayed on the dial-in screen as the
disconnect reason.
