DS31256

256-Channel, High-Throughput

HDLC Controller

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

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.

Cꢀ256 Independent, Bidirectional HDLC

Channels

CꢀUp to 132Mbps Full-Duplex Throughput

CꢀSupports Up to 60 T1 or 64 E1 Data Streams

Cꢀ16 Physical Ports (16 Tx and 16 Rx) That

Can Be Independently Configured for

Channelized or Unchannelized Operation

CꢀThree Fast (52Mbps) Ports; Other Ports

Capable of Speeds Up to 10Mbps

(Unchannelized)

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.

CꢀChannelized Ports Can Each Handle One,

Two, or Four T1 or E1 Lines

CꢀPer-Channel DS0 Loopbacks in Both

Directions

CꢀOver-Subscription at the Port Level

CꢀTransparent Mode Supported

CꢀOn-Board Bit Error-Rate Tester (BERT)

with Automatic Error Insertion Capability

CꢀBERT Function Can Be Assigned to Any

HDLC Channel or Any Port

APPLICATIONS

Channelized and Clear-Channel

(Unchannelized) T1/E1 and T3/E3

Routers with Multilink PPP Support

High-Density Frame-Relay Access

xDSL Access Multiplexers (DSLAMs)

Triple HSSI

CꢀLarge 16kB FIFO in Both Receive and

Transmit Directions

CꢀEfficient Scatter/Gather DMA Maximizes

Memory Efficiency

CꢀReceive Data Packets are Time-Stamped

CꢀTransmit Packet Priority Setting

CꢀV.54 Loopback Code Detector

CꢀLocal Bus Allows for PCI Bridging or Local

Access

High-Density V.35
