Frame Relay circuits (Encaps=FR_CIR)
A circuit is a PVC segment configured in two Connection profiles. Data coming in on the
DLCI configured in one Connection profile is switched to the DLCI configured in the other.
Data gets dropped if the circuit has only one DLCI. If more than two Connection profiles
specify the same circuit name, the MAX uses only two DLCIs.

Data gets dropped if the circuit has only one DLCI. If more than two Connection profiles
specify the same circuit name, the MAX uses only two DLCIs.
In a circuit, both Connection profiles must specify FR_CIR encapsulation and the same circuit
name. Each profile must specify a unique DLCI. The MAX does not allow you to enter
duplicate DLCIs, except when separate physical links specified in different Frame Relay
profiles carry duplicate DLCIs.

FR Direct connections (FR Direct=Yes)
In an FR Direct connection, the MAX simply attaches a Frame Relay PVC to multiple
Connection profiles. It does so in the Session Options subprofile, by enabling FR Direct,
specifying a Frame Relay profile, and setting a DLCI for the PVC endpoint in the FR DLCI
parameter. Any packet coming into the MAX on these connections gets switched out on the
DLCI. In this mode, the MAX allows multiple Connection profiles to specify the same PVC
(the same DLCI).

FR Direct is an unusual mode, in that the MAX ignores the destination of the packets. It
assumes that some device at the far end of the PVC makes the routing decisions. The
Connection profile, however, must use IP routing to enable the MAX to route data back to the
client.

Settings in a RADIUS profile
A permconn profile is a pseudo-user profile in which the first line has this format:
permconn-name-N Password="ascend", User-Service=Dialout-Framed-User
The name argument is the MAX system name (specified by the Name parameter in the System
profile), and N is a number in a sequential series, starting with 1. Make sure there are no
missing numbers in the series specified by N. If there is a gap in the sequence of numbers, the
MAX stops retrieving the profiles when it encounters the gap in sequence.
