Firmware and

CX27510 Edge Stream Processor

Integrated Multiservice Network

Edge Solution

The EdgeMaker/CX27510 platform deli vers a new class of

data link processing for both IP and ATM-based network edge

applications. EdgeMaker firmware running on the CX27510

Edge Stream Processor (ESP) delivers unique system-level

features such as:

• Multiple full-featured services including HDLC, AAL1, AAL2,

AAL5, IMA, and Cell Switching that can run concurrently and

be dynamically reconfigured with no processor downtime.

Enterprises deploying CPE equipment based on EdgeMaker

are insured against changing WAN service offerings as well

as ever-changing service pricing plans. Carrier equipment can

support on-demand service provisioning of any service, on

any link, down to a single DS0.

• DiffServ-enabled services, supporting multiple priority classes and

queuing on a per logical channel basis. Voice, video, and multiple

data class traffic can be prioritized and shaped on a single

connection to ensure optimal and desired network behavior.

• A high-level API with consistent look-and-feel across all services.

This API accelerates time to market and allows for development

leverage across multiple applications/services.

Written for the CX27510 ESP, EdgeMaker firmware provides

communication services up to OC-3 rates over TDM, xDSL, UTOPIA,

and PCI interfaces. A powerful suite of development tools to ease

system design, create value-added applications, and adapt to new

or changing standards is also available.

Distinguishing Features

Edge Stream Processing Services

EdgeMaker running on the CX27510 deli ver s a broad

set of industry-standard communication services

which integrates pack ets and Nx56/64 Kbps TDM

circuits over IP, xDSL, and ATM network connections.

The following services are included:

•Service-Frame: An HDLC controller facility

that can be used to implement packet-based

data link protocols such as PPP and Frame Relay.

HDLC functions such as CRC-16, CRC-32, bit

stuffing/de-stuffing, FCS checking/generation

and flag detection/generation are provided. HDLC

channels are supported on unchannelized links or,

for NxDS0 connections, on channelized links.

•Service-AAL1: Service-AAL1 is an I.363.1-

compliant AAL1 SAR firmware module capable of

providing circuit emulation for all TDM interfaces

utilizing either structured (SDT) or unstructured

data transfer (UDT). Service-AAL1 SDT can map an

entire T1/E1 or selected DS0s from a link to an ATM

channel. It supports CAS and partial cell-fill modes.

Service-AAL1 UDT provides circuit emulation for

DS1 and E1s. Integrated SRTS or adapti ve clock

support requires no external hardware.

•Service-AAL2: Service-AAL2 is an I.363.2-

compliant AAL2 SAR supporting CPS layer

switching, Traffic Management 4.0, and raw cell

insertion and extraction. Service-AAL2 supports

672 voice channels with typical CODECs.

•Service-AAL5: Service-AAL5 is an I.363-compliant

AAL5 SAR for bi-directional data traffic up to OC-3,

with support forTraffic Management 4.0 shaping,

four traffic priorities, and four class of service

queues per VC.

•Service-IMA: Service-IMA is an ATM Forum

Ver sion 1.1-compliant cell processing service

supporting all protocol cell formats, frame formats,

and state behaviors for up to 16 T1/E1 IMA links

which can be combined into any number of IMA

groups. IMA groups can be used to transport cells

from a mixture of ATM AAL5, AAL2, and AAL1

services. Service-IMA creates an IMA port which

can be connected to other ATM-based services

or switched to cell ports.

•Service-Switch: Service-Switch allows the

transparent transfer of up to 16 logical PHYs

without any translation or conver sion. Congestion

management features such as CLP water marking,

early and partial pack et discard, and policing are

available. Shaping is performed on a per VC bases.

Support for host insertion and extraction of OAM

cells is provided.

Hardware Features

The core of the CX27510 is the network-optimized

SWAN™ processor, which combines the pipelined

architecture of a RISC processor with the CISC-like

instruction set of a specialized communications

processor. Standard pack et, cell and circuit interfaces

are tightly coupled with the high-performance

communications-processing engine to support

WAN edge applications.

EdgeMaker Firmware and

CX27510 Edge Stream Processor

The Level II-compliant, pack et-extended UTOPIA port

operates as an 8-bit, bi-directional interface and supports

master or slave mode. The UTOPIA port supports 52-, 56-

and 60-byte cells and a POS PHY interface mode.The host

interface for the CX27510 is provided by a revision 2.1-

compliant PCI interface. Byte lane swap capabilities are

provided for ease of design in Little Endian systems. Up

to sixteenTDM interfaces can support 24, 32, 64, 96 or 128

DS0 timeslots for T1/E1 interfaces or computer telephony

buses. The TDM interfaces provide inline CAS support,

DS0 tri-state control, independent TX and RX clocks, and

multiframe synchronization. No external circuitry is needed

to support adaptive and SRTS clocking.

Application Examples

Integrated Access Devices

An integrated access device (IAD) combines several stand-

alone communications functions into one manageable,

cost-effective solution. The EdgeMak er/CX27510 combination

is an ideal platform for such an application. By using a

CX27510 ESP in the depicted WAN access card configura-

tion, a high level of networking integration can be achieved

on a single service card and a common software platform.

In this example, the EdgeMaker/CX27510 combination is

used to simultaneously manage LAN data and compressed

and uncompressed voice traffic between the enterprise

and WAN. With the breadth of interfaces inherent to the

CX27510 architecture, it works across a multitude of WAN

edge infrastructures including NxT1/E1, Frame Relay, xDSL,

ATM, OC-3 and DS3. EdgeMak er firmware enables industry-

standard, best-of-breed, multiserving across all interfaces.

Multiservice Edge Concentrator

Multiservice edge switching is another application that

takes advantage of the processing power and ver satility

of the EdgeMaker/CX27510 platform. The TDM interfaces

— up to 16 links — connect gluelessly to T1/E1 framer chips

and offer flexible support for a variety of circuit-based

applications. At the same time, the Level I/II-compliant

bi-directional UTOPIA interface, built into the CX27510,

provides a means of transmitting over a switching fabric.

Using the CX27510 within an edge switching card, as

illustrated, the EdgeMaker firmware package services an

assortment of internetworking applications at the access

point between a customer premise and the core of an ATM

network. EdgeMaker deli ver s unprecedented provisioning

speed and flexibility to service providers. This flexibility

enables equipment vendors and service providers to

reduce their inventory requirements.

Development Tools

The ESP DesignToolkit provides a full-featured set of

hardware and software co-development tools for the ESP

product family. The toolkit reduces design-cycle time

significantly by allowing hardware integration, software

integration and debugging to start early in the product-

development cycle. The toolkit consists of a hardware

and software co-simulator, an assembler and a debugger.

The ESP SIMMaker™ toolkit provides simulation models

(SWIFT and Verilog), test benches, bus functional models,

IBIS models and a reference design. Reference code is

provided to facilitate host application integration. A

comprehensive set of diagnostics is provided to assist

with testing. ESP SIMMaker is included as a part of the

ESP Design Toolkit or it can be ordered separately.
