GENERAL DESCRIPTION
The DS31256 Envoy is a 256-channel HDLC
controller that can handle up to 60 T1 or 64 E1
data streams or two T3 data streams. Each of the
16 physical ports can handle one, two, or four
T1 or E1 data streams. The DS31256 is
composed of the following blocks: Layer 1,
HDLC processing, FIFO, DMA, PCI bus, and
local bus.
There are 16 HDLC engines (one for each port)
that are each capable of operating at speeds up
to 8.192Mbps in channelized mode and up to
10Mbps in unchannelized mode. The DS31256
Envoy also has three fast HDLC engines that
only reside on Ports 0, 1, and 2. They are
capable of operating at speeds up to 52Mbps.
