SYMMETRIC HIGH-BIT-RATE DSL INTERFACE CARD FOR CISCO 1800, 2800, AND 3800 SERIES INTEGRATED SERVICES ROUTERS AND CISCO 1700, 2600XM, 2691, AND 3700 MULTISERVICE ACCESS ROUTERS

Cisco® multiservice access routers and integrated services routers offer a wide variety of WAN connectivity modules to accommodate the range of application needs in customer networks. The new Cisco 1-Port G.SHDSL WAN Interface Card (part number WIC-1SHDSL-V3) offers G.SHDSL-based WAN connectivity for modular routers deployed in small to medium-sized branch offices (Figure 1).

OVERVIEW

The new G.SHDSL WAN interface card (WIC) provides 1-port symmetric high-bit-rate DSL (SHDSL) connectivity to a WAN. The modular routers that support the new card are the Cisco 1841, 2801, 2811, 2821, 2851, 3825, and 3845 series integrated services routers; the Cisco 1721, 1751, 1760, 2600XM, 3725, and 3745 series multiservice access routers; and the Cisco 2691 Multiservice Platform. The interface card is available on Cisco access routers, starting with Cisco IOS® Software Release 12.4(3) Mainline and special Cisco IOS Software Release 12.4(2)XA. The first T-train image that will support the new interface card will be 12.4(3rd)T.
The new interface card is the latest G.SHDSL-based WIC for Cisco modular routers. It supersedes existing interfaces (part numbers WIC-1SHDSL and WIC-1SHDSL-V2) while maintaining feature parity with WIC-1SHDSL-V2. (Table 4 later in this document compares the three interface cards.)
G.SHDSL technology offers customers high-speed, symmetrical WAN connectivity at a lower monthly cost than most traditional WAN circuits. Using single or dual-pair copper wires, Cisco access routers with SHDSL interface card (part number WIC-1SHDSL-V3), can provide businesses the necessary bandwidth for critical traffic such as voice and videoconferencing, and can allow customers to save money by integrating voice and data traffic on the same WAN link. Service providers can increase subscriber revenue by bundling services and offering differentiated service levels through service-level agreements (SLAs).
A product of the ITU-T, SHDSL is the first standardized multirate symmetric DSL technology. It is designed to transport rate-adaptive symmetrical data across a single copper pair at data rates from 192 kbps to 2.3 Mbps, or 384 kbps to 4.6 Mbps over two pairs. This covers applications traditionally served by high-bit-rate DSL (HDSL), symmetric DSL (SDSL), T1, E1, and services beyond E1. G.SHDSL represents the worldwide-accepted DSL standard for symmetrical DSL, based on ITU recommendation G.991.2.

Permanent-virtual-circuit (PVC) traffic shaping and queuing allow further optimization of the existing bandwidth between customers and various services.

INTEROPERABILITY

The new interface cards are based on the Conexant chipset (Firmware 3.0.1), and they operate when connected back to back or when connected to a DSLAM.
Customers can deploy G.SHDSL WICs in a back-to-back configuration to take advantage of existing copper wiring in a building, campus, or neighborhood where DSLAM aggregation equipment is neither needed nor financially justified. In back-to-back mode, one side of the connection is configured in central-office mode and provides functions similar those of a DSLAM (Table 3).

ADVANCED TRAFFIC MANAGEMENT

Advanced traffic management mechanisms in the DS3/E3 ATM network modules architecture allow for the support of bursty, client/server traffic, while supporting applications that require guaranteed or best-effort service. The ATM DS3/E3 supports all the ATM service classes, including UBR, UBR+, VBR-rt, VBR-nrt, and ABR. Supporting these ATM service classes allows the DS3/E3 network modules to concurrently support various network applications on the same ATM interface. VBR-rt is intended for applications that require guaranteed services, and ABR and UBR are intended for applications that need only "best-effort" service.
The ABR support includes the Explicit Rate (ER), Relative Rate (RR), and Explicit Forward Congestion Indicator (EFCI) modes. ABR was defined specifically to minimize cell loss and maximize good put through the ATM network. Explicit Rate ABR is typically deployed in ATM WAN switches, and is used in products such as Cisco's 8400/IGX and 8800/MGX ATM switches. Relative Rate ABR is more effectively deployed in the campus and is supported by the Cisco Lightstream 1010, and 8500 series ATM switches. EFCI is typically used for backward compatibility with legacy ATM switches that support neither Explicit nor Relative Rate.

Table 2. ATM Service Class Definitions

ATM Service Classes

Typical Use

VBR-nrt-non-real time Variable Bit Rate

Used for all applications that require a level of Service guarantee through the ATM.

VBR-rt-real-time Variable Bit Rate

Used for connections that transmit at a rate varying with time and that can be described as bursty,
often requiring large amounts of bandwidth when active. Intended for applications that require tightly constrained delay and delay variation such as compressed VoIP and video conferencing.

ABR-Available Bit Rate

Used to maximize bandwidth utilization on the ATM link through the use of congestion feedback notification.

UBR-Unspecified Bit Rate

Most legacy data applications using fair best-effort service.

CBR-Constant Bit Rate

Provides guaranteed bandwidth for data applications such as SNA traffic.

PER-VC TRAFFIC SHAPING

Traffic shaping is a function typically provided on ATM edge devices to ensure that bursty traffic conforms to a predetermined Service Level Agreement (SLA). More specifically, traffic shaping ensures that traffic from one VC does not adversely impact another, resulting in data loss. This function is very important when connecting to an ATM WAN or public ATM network-especially when the ATM switches enable traffic policing that will discard all traffic that exceeds the predetermined contract at the ingress of the switch.
The ATM DS3/E3 supports traffic shaping in hardware which eliminates performance degradation when shaping is enabled. Providing traffic shaping on a per-VC basis in done by the software using IP-to-ATM CoS mapping feature and allows total flexibly and control over every VC configured.
For each ATM service class, the ATM DS3/E3 supports highly configurable parameters: peak cell rate (PCR), sustainable cell rate (SCR), maximum burst size (MBS) and minimum cell rate (MCR). These parameters can be defined based on the specific bandwidth requirements of an individual VC, as needed for a specific application.

The ATM DS3/E3 hardware "shapes" the VC to the specific parameters using a wheel-based scheduling algorithm to ensure fairness across the ATM interface. In the event that two cells compete for the same time slot, the VCs are prioritized in the following order (starting with highest priority): 1) OAM cells and signaling; 2) nrt-VBR; 3) ABR; and 4) UBR. Prioritizing the VCs in this manner ensures that the high priority and guaranteed traffic have precedence over the best-effort traffic.
To provide further flexibility, the ATM DS3/E3 allows each of these parameters to be set over a wide range of small increments.

Digital J1 Packet Voice
Network Module


The Digital J1 Packet Voice Network Module provides a flexible and scalable J1 voice and fax solution for the Cisco 2600, 2600XM, 3600 and 3700 series multiservice Modular Access routers and supports up to 30 voice channels in a single network module. A single packet voice network module supports connections to Japanese Private Branch Exchanges (PBXs), and is compliant with the J1 TTC JJ20 standard. The network module eliminates the need to use expensive external third-party T1 to J1 converter products. This network module is ideal for enterprise branches, large businesses and service providers wishing to migrate to packet-based multiservice infrastructures. It also enables the deployment of new packet voice applications while reducing recurring telephony charges.


Figure 1   Digital J1 Packet Voice Network Module (NM-HDV-1J1-30E Pictured)

The Digital J1 Packet Voice Network Module uses a real-time CPU and 12-channel packet voice digital signal processing (DSP) modules (PVDM-12) which support all functions needed to provide the highest levels of voice fidelity and quality, reducing the processing burden from the Cisco 2600, 3600 or 3700's main CPU. The packet voice network module includes a VIC-1J1 voice interface card which offers a single port J1 voice/fax interface.

Now, enterprise offices of several hundred users and managed network service providers can deploy multiservice networking using a single box solution.

Key Features and Benefits

  • Interface to Japanese PBXs to route voice and fax, eliminating the need for an expensive external third-party T1 to J1 converter product.
  • Programmable digital signal processors can support both medium- (G.729A, G.729B, G.711a- and u-law, G.726 all versions, clear-channel, fax-relay) and high-complexity CODECs (G.728, G.729, G.729B, G.723 all versions, GMS, GSMEFR, modem relay) for customized solutions to meet the need for high voice quality and bandwidth efficiency
  • Packet Voice Digital Signal Processor Modules (PVDM-12=) provide the ability to increase the voice processing capabilities within a single network module
  • Support of additional modular voice processing requirements on the Cisco 2600, 3600 and 3700 platforms such as routing, dial concentration, firewall, encryption and VPN.

Feature Summary

Table 1   Digital J1 Packet Voice Network Module Feature Summary

Feature Benefits
J1 Standards Support

Supports the TTC JJ-20.10-12 standard with a line rate of 2.048 Mbps

Scalable from 1 to 30 Voice Channels

Single Network Module scales using from one to five 12-channel packet voice DSP module (PVDM-12) upgrade SIMMs to support from 1 to 30 voice channels.

Standards-Based PCM Encoding

Standards-based ITU-T G.711 PCM encoding provides 64 kbps analog to digital conversion using u-law or A-law.

Standards-based Compression Algorithm Support

Users can choose to either transmit voice across their networks as uncompressed PCM (G.711, u-law and A-law) or compressed from 5.3 kbps to 32 kbps using standards-based compression algorithms (G.729, G.729a/b, G.723.1, G.726, G.728).

Fax Support

Transmit Group III fax and T.38 over any voice channel without sacrificing voice processing resources regardless of compression type.

Voice over IP

Transmit voice across a single frame relay, ATM, ISDN, channelized, or multilink point-to-point protocol (MLPPP) network.

Voice over Frame Relay

Leverage existing or new frame relay network by transporting voice directly over this network using standards based transport methods (FRF.11). VoIP can also be transmitted over Frame Relay.

Voice over ATM

Transport voice directly over ATM networks using AAL 5 encapsulation. Leverages existing ATM networks as a direct transport method for voice. VoIP can also be transported over ATM (VoATM requires ATM network modules such as IMA or OC-3).

Connection Trunk

Creates a tie-line replacement structure while only consuming bandwidth during a call.

Toll Bypass

Reduce or eliminate toll charges assessed by long distance and local carriers by transporting voice and fax traffic across the enterprise intranet, LAN, metropolitan-area network (MAN), or WAN. Businesses incur significant recurring monthly costs for leased lines purely for the interconnection of telecom PBXs and switches. This product gives these enterprises the ability to remove these costly rigid-bandwidth leased lines and replace them with flexible bandwidth lines. The ability to support proprietary PBX signaling types exists by using connection trunking and transparent CCS.

LVBO (Local Voice Busy-Out) and AVBO (Advanced Voice Busy-Out)

Automatically busy out any desired voice trunk line (or individual DS0s) to a PBX when a direct WAN or LAN connection to the router is down. Also, busy out a far end trunk connection when configured for Connection Trunk. AVBO adds the capability to busy out voice trunk lines triggered by Security Assurance Agent (SAA) probes.

Local and Remote Loopback

Supports three types of loopback modes - line and local loopback, and isolation.

T-CCS (Transparent Common Channel Signal)

Supports clear channel transparent common channel signaling

J1 CAS (TTC JJ-20.10-12)

Supports J1 channel associated signaling

H.323 Support

Uses industry-standard signaling protocols for call setup between gateways, gatekeepers, and H.323 end points. Enables comprehensive, flexible application configuration for voice over IP, desktop video conferencing, collaborative computing and electronic whiteboard applications.

DTMF Relay

Carries DTMF tones/information out-of-band for clearer transmission and detection.

Any Call to Any Call with end-to-end Interoperability

Interoperates with Cisco IP phones, analog phones, fax machine connections, and PBX connections to and from any other Cisco voice enabled product.

AVVID IP Telephony Interoperable
