PPP Mappings parameters

The PPP Mappings page contains two columns of as many interfaces as are supported by the
router (this varies between models). Each row in the column contains a drop-down list box that
allows the user to select what function should be associated with each PPP instance. The PPP
instance number is the left-most column. So, for example, to assign a W-WAN interface to PPP
instance 3, select Mobile SIM1 or SIM2 from the drop-down box to the right of instance 3. If a W-
WAN interface is fitted to the router, this is the default mapping.
Multilink PPP parameters
As mentioned above, the routers may support multilink PPP. This section describes the
configuration of MLPP functionality.
The PPP interface must be configured with Always On mode enabled and an AODI NUA.
Desired local ACCM c
The value in this textbox defines the Asynchronous Control Character Map (ACCM). The
default value of 0x00000000 should work in most cases. Changing this value is for advanced
users only.
Desired remote ACCM c
The value in this textbox defines the ACCM for the remote peer. As above, the default value of
0xffffffff should work in most cases and should only be changed if it is known that other
characters should be used.
Username
The value in this textbox is the username that should be used for logging on to the remote
system.
Password
The value in this textbox is the password that should be used for authentication with the
remote system when using MLPP. This password is used for both B-channel PPP connections.
Confirm password
When changing the password, the new password should also be typed into this text box. The
router will check that both fields are the same before changing the value.
Enable remote CHAP authentication
When checked, this checkbox causes the router to authenticate itself with the remote system
using CHAP. If this parameter is set, the connection will fail if authentication fails. Generally,
this checkbox should be left unchecked.
