DS31256DK Envoy  
256-Channel, High-Throughput  
HDLC Controller Demo Kit  
www.maxim-ic.com  
GENERAL DESCRIPTION  
FEATURES  
The DS31256 Envoy is a 256-channel HDLC  
controller capable of handling up to 64 T1 or 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 Envoy 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 64 T1 or 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 Envoy also  
has three fast HDLC engines that only reside on  
Ports 0, 1, and 2. They can operate 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  
High-Density V.35  
CꢀReceive Data Packets are Time-Stamped  
CꢀTransmit Packet Priority Setting  
CꢀV.54 Loopback Code Detector  
CꢀLocal Bus Allows for PCI Bridging or Local  
Access
