4-80 MAX 6000/3000 Network Configuration Guide
Configuring Individual WAN Connections
Configuring terminal-server connections
• V.120 maximum receive frame size=260 bytes.
• Logical link ID=256.
• Modulo=128.
• Line channel speed: Select 56K if the unit accepts calls from the V.120 device on a T1
line, or if you are not sure that you have 64-Kbps channel speed end-to-end.
After checking the configuration of the V.120 device, make sure you enable V.120 calls in the
Answer profile. For example:
Ethernet

V.120=Yes
V.120 Options
Frame Length=260
To configure a connection that uses a V.120 terminal adapter, create a Connection profile. For
example:
Ethernet
Connections
abby
Station=abby
Active=Yes
Encaps=PPP
Encaps Options
Recv PW=localpw
Session Options
TS Idle Mode=Input
TS Idle=60
For information about these parameters, see “Session Options” on page 4-35 and “Example of
a single-channel PPP connection” on page 4-43.
TCP-Clear connections
Use a TCP-Clear connection for username logins or TCP modem connections. In most cases,
use TCP-Clear to transport custom-encapsulated data understood by the host and the caller. For
example, customers who log in from an ISDN device typically use a TCP-Clear connection to
tunnel their proprietary encapsulation method in raw TCP/IP packets, as shown in Figure 4-14.
Figure 4-14. A TCP-Clear connection
Note: A TCP-Clear connection is host-to-host. As soon as the MAX unit authenticates the
connection, the host establishes a TCP connection as specified in the Connection profile.
