The Cisco® Connected Grid portfolio of solutions is designed specifically for the harsh, rugged environments often found in the energy and utility industries. These solutions include the Cisco 2010 Connected Grid Router (CGR 2010), which has been designed to support the communications infrastructure needs of the energy delivery infrastructure across the generation, transmission, and distribution sectors. Designed for highly secure, reliable, and scalable infrastructure, the CGR 2010 is an ideal platform to support Smart Grid and other energy delivery infrastructure needs of customers. The CGR 2010 has been extensively tested to meet the challenging substation compliance standards including IEEE 1613 and IEC 61850-3. The CGR 2010 offers four module slots to utilize Grid Router WAN Interface Cards (GRWIC). These GRWICs support legacy WAN interfaces (such as ISDN, DSL, Serial, etc) as well as new WAN technologies such as 4G Long Term Evolution (4G LTE).

Product Overview

Cisco Connected Grid Multimode VDSL2 and ADSL2/2+ GRWIC

The Cisco Multimode VDSL2 and ADSL2/2+ GRWICs provide 1-port multimode VDSL2 and ADSL2/2+ WAN connectivity. In combination with the CGR 2010, this GRWIC provides high-speed digital data transmission between remote energy infrastructure and the central office (DSL access multiplexer [DSLAM]), usually located on the service provider premises. This capability helps enable the energy operations to take advantage of the business-class WAN connection features such as security, differentiated classes of service (QoS), and managed access with Cisco IOS ® Software over existing telephony infrastructure. These value-added features, along with the flexible manageability and reliability of Cisco IOS Software, provide mission-critical networking features that energy organizations need.

Cisco Symmetric High-Bitrate (G.SHDSL) GRWIC

The 2-pair (GRWIC-2SHDSL) symmetric high-bit-rate DSL GRWIC provides two ports of 2-wire or one port of 4-wire G.SHDSL connectivity to a WAN. G.SHDSL technology offers customers high-speed, symmetrical WAN connectivity at a lower cost than traditional WAN circuits. Together with the CGR 2010, the GRWIC provides energy infrastructure organizations with the necessary bandwidth for critical traffic and helps enable the option for point-to-point DSL that does not require a service provider.
The first standardized multirate symmetric DSL, G.SHDSL has been an accepted worldwide technology standard based on International Telecommunication Union's (ITU) recommendation G.991.2. G.SHDSL is designed to transport rate-adaptive symmetrical data across a single copper pair at data rates up to 2.304 Mbps for a
single pair, or up to 4.608 Mbps over two pairs. This rate covers applications traditionally served by HDSL,SDSL, T1, E1, and services beyond E1. Figure 1 displays the Cisco Connected Grid Multimode VDSL2 & ADSL2+ and G.SHDSL GRWICs

Application-Aware Networking with IP Quality of Service

Using Cisco quality-of-service (QoS) features, including Class-Based Weighted Fair Queuing (CBWFQ), Low-atency Queuing (LLQ), Weighted Random Early Detection (WRED), etc., the Cisco 2000 Series Routerswith the Cisco Multimode VDSL2 and ADSL2/2+ GRWIC can help service providers and resellers offer services that can differentiate bandwidth based on the specific application or user.

Performance

VDSL2 and ADSL2/2+ performance is a function of many variables, including the DSLAM line card, DSLAM software version, VDSL profile and band plan, line-noise conditions, loop length, and other environmental factors.

Platform Support

Multimode DSL (VDSL2 and ADSL2/2+) GRWICs are supported only in the onboard GRWIC slots of the modular CGR 2010 platofrm. Table 6 provides platform support details.

Differentiated Service Offerings Through IP and ATM QoS

Using Cisco QoS features including Class-Based Weighted Fair Queuing (CBWFQ), Low-Latency Queuing (LLQ), Weighted Random Early Detection (WRED), etc., the Cisco CGR 2010 with the G.SHDSL GRWICs help energy infrastructure organizations differentiate bandwidth based on a specific application or a specific user. In addition to IP QoS features, the Cisco CGR 2010 with the G.SHDSL HWICs map IP QoS to ATM CoS features, including support for constant bit rate (CBR), Variable Bit Rate non-realtime (VBR-nrt), Variable Bit Rate realtime (VBR-rt), Unspecified Bit Rate (UBR), and UBR+. These features help manage core ATM network infrastructures to deliver scalable, cost-effective services with QoS guarantees to customers. Per-virtual-circuit traffic shaping and queuing allows further optimization of the existing bandwidth between customers and various services.

Data Rates Supported with 2-Pair G.SHDSL GRWIC

Table 9 details the data rates for 2-pair G.SHDSL HWICs. Note that actual data rates depend upon factors such as loop length, line conditions, DSL Access Multiplexer (DSLAM) linecard and chipset and data rates provisioned by the service provider.
