V.120 terminal-adapter connections
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 retransmission s (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..
Note: 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 encap sulation 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.
