Cisco 6160 IP DSL Switch


The Cisco 6160 is a 32-slot, multiport line-card architecture that supports industry-standard asymmetric digital subscriber line (ADSL), and high-speed symmetric digital subscriber line (SHDSL) line technologies. Targeting North American central-office environments, the Cisco 6160 is fully compliant with relevant Network Equipment Building Standards (NEBS), American National Standards Institute (ANSI), and ATM carrier-class network-element standards. Network transmission connections include DS3, 8xT1 inverse multiplexing over ATM (IMA), OC-3c single mode, and OC-3c multimode. Up to 256 ports per chassis can be provisioned with ADSL (discrete multitone [DMT]), G.shdsl. A variety of configuration and cabling options are available to support a mix of xDSL services within a common chassis. For "above voice-band" or "line sharing" ADSL applications, the Cisco 6160 can also be used with various third-party Plain Old Telephone Service (POTS) splitters.

The Cisco 6160 provides an evolution path from today's unspecified bit rate (UBR)-oriented Internet access service model, popular for most high-volume consumer DSL service rollouts, to a comprehensive UBR, constant bit rate (CBR), nonreal-time variable bit rate (VBR-nrt), real-time variable bit rate (VBR-rt), and available bit rate (ABR) class of service (CoS) family required for the growing demands of telecommuter and business customers with mission-critical applications. In addition to supporting industry-leading traffic management through I.371-compliant policing, extensive-output queue buffering, and virtual path (VP)-granularity shaping, the Cisco 6160 platform can provide the kind of robust ATM capabilities typically found only in edge-switch or higher-class products. Individual rate schedulers can support up to 3328 ports with a subtended configuration, allowing network providers to extract maximum value from each network trunk connection without creating the "parking lot" problem characteristic of first-generation DSLAM architectures.

The Cisco 6160 is deployed with Network Interface Card (NI-2) based common cards, which can be managed via the Cisco DSL Manager. The Cisco DSL Manager network management system is a complete Simple Network Management Protocol (SNMP)-based element management system with fault, configuration, and performance reporting capabilities. A Cisco IOS® Software command-line interface (CLI) is also available for craft interaction.

Key Features and Benefits

  • Multiservice DSL—The Cisco 6160 offers a wide variety of DSL line cards in 4- and 8-port densities for support of standards-based ADSL and SHDSL technologies. ADSL line cards support full-rate operation per G.992.1 (G.dmt) and ANSI T1.413 Issue 2 with data rates up to 8-Mbps downstream and 1-Mbps upstream. G.992.2 (G.lite) operation is also supported, offering data rates up to 1.536-Mbps downstream and 512-kbps upstream. SHDSL line cards offer data rates of up to 2.312 Mbps symmetric.

  • Advanced IP+ATM services architecture—The Cisco 6160 internal design is based on a high-performance, nonblocking ATM switching architecture that also encompasses IP Layer 3 services. The ATM switching architecture supports all ATM service classes including CBR, VBR, VBR-nrt, UBR, ABR, and the richest set of ATM traffic management and shaping capabilities. Revenue-generating, differentiated Layer 3 IP services include Multiprotocol Label Switching (MPLS), subscriber termination Point-to-Point Protocol over ATM, Ethernet (PPPoA/E), Layer 2 Tunneling Protocol (L2TP) tunneling, and routing bridging encapsulation (RBE).

  • Network management support—The Cisco DSL Manager provides comprehensive Cisco 6160 element management and operations support based on standard SNMP. Additionally, using standards-based network management interfaces and protocols, the Cisco DSL Manager can be directly integrated with other Cisco or customer-provided operations management systems for delivery of integrated, end-to-end service-management solutions.

  • Standards compliant—The Cisco 6160 fully conforms to UL1950, ICCS-003, FCC Part 15/Part 68, Telecordia GR-1089-CORE, and Telecordia GR-63-CORE (NEBS Level 3) as required for central office or co-location deployment. Compliance to ATM, ANSI, and International Telecommunications Union (ITU) standards is also provided.

Configuration Worksheets

To order and configure a Cisco 6160 DSL access concentrator, follow these steps:


Step 1.   Chassis—First, you need a Cisco 6160 Chassis. The chassis assembly also includes the backplane, DC power entry module (PEM), and fan assembly unit. The Cisco 6160 Chassis ships with an accessory kit that contains user and installation documentation and a rack-mounting assembly kit for 23-inch wide racks.

Step 2.   Power supply—If you need redundant power protection of the system, you can order an optional second PEM.

Step 3.   Software—Order the Cisco IOS base system software. The basic Cisco IOS Software provides support for a single Cisco 6160 chassis with up to 256 subscribers and ATM signaling and QoS. Review Cisco IOS Release Notes for specific feature enhancements and minimum system requirements.

Step 4.   Software options—In addition to the base Cisco IOS Software, several optional software feature packages are available depending on the feature and capabilities needed. These product options are listed here and further described below:

  • The Subtending feature license provides the capability to concentrate access traffic from 2 to 13 Cisco 6160s onto a single network (WAN) interface connected to a service provider network.

  • The MPLS feature license permits the Cisco 6160 to operate as an MPLS label edge router (LER) and support the creation of MPLS-based VPNs.

  • The OpenDSL Proxy feature license provides support of automated configuration of OpenDSL-compliant CPE, greatly simplifying DSL installations.

Step 5.   System cards—Specify the network interface card (NI-2) and I/O card options for the Cisco 6160. The NI-2 system card provides several major Cisco 6160 functions: It is the Cisco IOS Software processing platform; it contains the system ATM switch fabric; it provides the wide-area ATM network interface; it provides the ATM subtending interfaces; it provides the console and network management interfaces; and it provides the SNMP network management agent functionality. An important note is that if 8xT1 IMA operation is desired, the DS3+T1/E1 IMA NI-2 card
(P/N: NI-2-DS3-T1E1) must be ordered with the DS3/2DS3+8xT1 IMA I/O card (P/N: CHAS6160-W/IO-2).

The current Cisco 6160 configuration requires at least one NI-2 card. There are, however, two slots in the Cisco 6160 to support a redundant NI-2 card (requires Cisco IOS Software Release 12.1(7)DA).

Step 6.   Line cards—Configure the Cisco 6160 with DSL line cards. Minimum quantity is 1; maximum quantity is 32.

Step 7.   POTS splitters (optional)—To include voice telephone support (ADSL and POTS line sharing) with the Cisco 6160 (optional), order POTS splitter equipment through one of Cisco third-party suppliers. Contact a Cisco sales representative for more information.
