Data Sheet

Cisco 6015 IP DSL Switch

  Product Overview

The industry-leading Cisco 6000 Series IP DSL Switches supports the most comprehensive set of IP+ATM capabilities with common multi-DSL technologies for central offices (COs), remote terminals, and multitenant/multiple dwelling units (MTUs/MDUs).

The Cisco 6000 Series is IP ready and enables an evolution path to IP+ATM managed services, such as Multiprotocol Label Switching/virtual private networking (MPLS/VPN), multicasting, and Internet protocol (IP) routing/quality of service (QoS). The Cisco 6015 IP DSL Switch is a key addition to the 6000 series, extending the DSL reach beyond the CO to the outside plant (OSP) and MDU. The Cisco 6015 is a companion to the Cisco 6160 and 6260 products, with an ideal form factor for smaller-scale DSL deployments, but with the same robust IP+ATM features of the larger products. The Cisco 6015 is designed for commercial deployments in incumbent local exchange carrier (ILEC), international post, telephone, and telegraph (PTT), and competitive local exchange carrier (CLEC) networks, as well as MTUs/MDUs. An environmentally hardened system is available for OSP deployments.

Cisco 6015 Product Overview

The Cisco 6015 is a front-access, six-slot multiport line-card architecture capable of supporting industry-standard asymmetric DSL (ADSL) and single-pair high-bit-rate DSL (G.shdsl) technologies. The product is fully compliant with Network Equipment Building System (NEBS), American National Standards Institute (ANSI), European Telecommunication Standards Institute (ETSI), and asynchronous transfer mode (ATM) carrier-class network-element standards. Network transmission connections include T1/E1 inverse multiplexing over ATM (IMA), DS3 User-Network Interface (UNI), and OC-3/Synchronous Transport Module level 1 (STM-1) UNI. Up to 48 ADSL or G.shdsl ports can be provisioned for use with the Cisco 6015 in a variety of configurations. The Cisco 6015 supports simultaneous voice (basic telephone service) and data services with the addition of a specially designed plain old telephone service (POTS) Splitter package that is available from Cisco Ecosystem Partner Program members.

Building on the advanced network interface (Network Interface—version 2 [NI-2]) architecture of the Cisco 6160 and 6260 IP DSL Switches, the Cisco 6015 provides a clear migration path from today's unspecified bit rate (UBR)-oriented Internet access service model (popular for high-volume consumer DSL service rollout), to a comprehensive IP+ATM (class of service [CoS])/QoS 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 6015 platform can provide the kind of robust IP+ATM capabilities typically found only in edge-switch or higher-class products. Refer to Table 1 for complete product specifications.

Cisco DSL Manager manages the platform and 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 network-element provisioning. Management solutions are also being extended to include flow-through provisioning with carrier-class network management systems (NMSs).

Key Features and Benefits

  • Telco CO environments—The small footprint and desirable form of the Cisco 6015 is well-suited for smaller-scale DSL CO applications. The product is equipped with the same full-featured DSL and ATM interface architecture as larger Cisco DSL access multiplexers (DSLAMs). This product gives telcos flexibility to deploy DSL services from small COs, subtend off of larger platforms, or co-locate in constrained spaces.

  • MTU/MDU—The compact design of the Cisco 6015 is perfect for telco closets or basement installations. An optional external AC power supply is available for these installations. The wide area network (WAN), subtend, and DSL lines of the Cisco 6015 are entirely front-accessible for easy installation and maintenance. Class B compliance ensures universal installation and access, regardless of the location.

  • Remote terminal environments—The Cisco 6015 is available with hardened common cards and line cards to withstand operational conditions in OSP environments. Adding remote terminal deployment capabilities extends the reach of DSL to virtually 100 percent of the total addressable market. The Cisco 6015 can be installed in existing and new remote terminals, huts, and controlled environmental vaults (CEVs), extending DSL services to remote locations in the service provider's network. This optimized platform provides a high-density solution for the remote terminals.

  • Multiservice DSL—ADSL line cards include standards-compliant ANSI T1.413 and future ITU G.shdsl. Full ADSL data rates are supported (8.024 Mbps downstream/864 kbps upstream for discrete multitone [DMT], and 1536 kbps downstream/512 kbps upstream for G.lite). G.shdsl data rates up to 2.3 Mbps symmetric are also supported. DSL subscriber train rates can automatically adapt to the highest attainable line speed based on individual loop characteristics, or they can be selectively provisioned based on a desired service definition.

  • MPLS VPN—MPLS on the Cisco 6015 IP DSL Switch enables providers to offer the benefits of IP services over their ATM infrastructures. Service providers can use MPLS to build an entirely new class of IP virtual private network (VPN). MPLS-enabled IP VPNs are connectionless IP networks with the same privacy as Frame Relay (FR) and multiple IP service classes to enforce business-based policies. Providers can offer low-cost managed IP services because MPLS-based VPNs make operations much more efficient.

  • Scalable architecture—The six line-card slots are capable of supporting ADSL or G.shdsl line cards. The Cisco 6015 is equipped with a proven ATM switching fabric and traffic-management feature set required for quality Internet-access provisioning.

  • Standards compliant—The Cisco 6015 fully conforms to UL, Bellcore, and ETSI standards as required for central office or outside plant deployments. In addition, the product is fully FCC Part 15 Class B compliant for installations in MTU/MDUs.
