ACCESS, which is connected to a Frame Relay Router at the

user’s site.

For addressing the WIMAN ACCESS the DLCI number (Data

Link Connection Identifier) of the Frame of Relay protocol is

used.

The following restrictions apply to the Frame Relay support:

• Only static connections are supported (PVC = Permanent

Virtual Connection)

• DLCI numbers must be configured statically on the Frame

Relay Switch and the Frame Relay Router

• 2-, 3- or 4- Byte-Frame Relay-address-arrays are supported,

number (10-bit DLCI with implemented WIMAN node

identifier), the DLCI allocation of numbers is reduced

• Up to four virtual connections are supported for each Frame

Relay user

• Up to 250 Frame Relay users are supported at a WIMAN

STAR (currently 9 users possible, Software Version T0.7).
