Black Zone performance monitoring of both the near-end and far end

can be done from the Red Zone.

■

Increased bandwidth

REMS uses the full 1.544 Mbps bandwidth at all points. A 14%

increase in bandwidth is realized when you compare the

uncompromised 1.536 M bps provided by the REMS with the

1.34 4Mbps limit of the “slow down” technique.

REMS system

hardware

configuration

Each AS2000 REMS termination consists of two parts:

■

a Black to Red Communicator (BRC/CSU), located in the Black

Zone, and

■

a Frame Bit Repositioner (FBR), located in the Red Zone.

Both the BRC and the FBR are designed to function within either the

Access System 2000 dual line-shelf (DLS 2000) or the “High Density”

multi-line shelf (MLS 2200).
