CHAPTER 5 Business LAN Management by
1
A GSWB (optional) provides frame relay on the data link layer (layer 2) and related
functions by using a dedicated CPU and memory.
GSWB firmware is installed in the GSWB, and controls the GSWB. GSWB firmware
is used via MMB firmware.
These firmware programs can be used to construct and manage a business LAN (user
LAN) used by a business system.
