V.120 terminal adapters (also known as ISDN modems) are asynchronous devices that use 
CCITT V.120 encapsulation. The values that work best for V.120 operation are:

•

Maximum information field size for send and receive packets=260 bytes.

•

Maximum number of retransmissions (N200) =3.

•

Logical link ID (LLI)=256.

•

Idle timer (T203)=30 seconds.

•

Maximum number of outstanding frames=7.

•

Modulo=128.

•

Retransmission timer (T200)=1.5 seconds.

•

Types of frames accepted=UI, I. (I-type frames are recommended.).

•

Call placement: The MAX unit can receive V.120 calls, but cannot place them..

If the connection uses PAP or CHAP authentication, the ISDN terminal adapter should 

be configured for async-to-sync conversion. In this case, V.120 encapsulation is not required in 
the Connection profile. For more information, see “Connection authentication issues” on 
page 4-78.

The V.120 device must be correctly configured to place calls to the unit. The settings required 
for compatible operation of a V.120 device and the unit are listed below. For information about 
entering these settings, see the V.120 manual.

•

V.120 maximum transmit frame size=260 bytes.
