  • Security
  • Embedded hardware-accelerated VPN encryption
  • Secure collaborative communications with Group Encrypted Transport VPN, Dynamic Multipoint VPN, or Enhanced Easy VPN
  • Integrated threat control using Cisco IOS Firewall, Cisco IOS Zone-Based Firewall, Cisco IOS IPS, and Cisco IOS Content Filtering
  • Identity management that uses authentication, authorization, and accounting (AAA), and public key infrastructure

Cisco Enhanced High Speed WAN Interface Card (EHWIC)

This card can be used for all of the inCloudOne® ADSL2+ services including Bonded and ADSL backup lines for our leased line circuits

  • The EHWIC slot replaces the high-speed WAN interface card (HWIC) slot and can natively support HWICs, WAN interface cards (WICs), voice interface cards (VICs), and voice/WAN interface cards (VWICs)
  • Two integrated EHWIC slots are available on the Cisco 1941 for flexible configurations for support of two modules: One double wide HWIC-D or single wide EHWIC/HWIC module and a second single wide E- HIC/HWIC module are supported
  • Each HWIC Slot offers high data throughput capability ◦ Up to 1.6 Gbps aggregate towards the router processor ◦ Up to 2 Gbps aggregate to other module slots over MultiGigabit Fabric (MGF)

Key Business Benefits

The Integrated Services Routers Generation 2 (ISR G2) provide superior services integration and agility. Designed for scalability, the modular architecture of these platforms enables you to grow and adapt with your business needs. Table 1 lists the business benefits of the Cisco 1900.

Delivers highly secure data, mobility, and application services.

Service Integration

  • The Cisco 1941 Series offer increased levels of services integration with data, security, wireless and mobility services enabling greater efficiencies cost savings.

Services on Demand

  • A single Cisco IOS® Software Universal image is installed on each ISR G2. The Universal image contains all of the Cisco IOS technology sets which can be activated with a software license. This allows your business to quickly deploy advanced features without downloading a new IOS image. Additionally, larger default memory is included to support the new capabilities.
  • The Cisco Services Ready Engine (SRE) enables a new operational model which allows you to reduce capital expenditures (CapEx) and deploy a variety of application services as needed on a single integrated compute services module.

High Performance with Integrated Services

● The Cisco 1900 Series enables deployment in high speed WAN environments with concurrent services enabled up to 25 Mbps.

● Multi-Gigabit Fabric enables high bandwidth module to module communication without compromising routing performance

Network Agility

  • Designed to address customer business requirements, Cisco 1941 Series with the modular architecture, offers performance range of modular interfaces and services as your network needs grow.
  • Modular interfaces offer increased bandwidth, a diversity of connection options, and network resiliency.

Energy Efficiency

  • The Cisco 1941 Series architecture provides energy savings features that include the following: ◦ The Cisco 1900 Series offers intelligent power management and allows the customer to control power to the modules based on the time of day.
  • Cisco EnergyWise technology will be supported in the future.
  • Services integration and modularity on a single platform performing multiple functions, optimizes raw materials consumption and energy usage.
  • Platform flexibility and ongoing development of both hardware and software capabilities lead to a longer product lifecycle, lowering all aspects of the total cost of ownership, including materials and energy use.
  • High efficiency power supplies are provided with each platform.

Investment Protection

  • The Cisco 1941 Series maximizes investment protection by supporting: ◦ Reuse of a broad array of existing modules supported on the original Integrated Services Routers provides a lower cost of ownership
  • Rich set of Cisco IOS Software features carried forward from the original Integrated Services Routers and delivered in the universal image.
  • Flexibility to grow as your business needs evolve

What do the different annexes specify?

The scope of the different annexes in G.992.5 is defined as follows:

  • Annex-A: This annex defines those parameters of the ADSL system that are unique to an ADSL service that is frequency division multiplexed with basic telephone service.
  • Annex-B: This annex defines those parameters of the ADSL system that are unique to an ADSL service that is frequency division multiplexed with ISDN BA on the same digital subscriber line.
  • Annex-M: This annex defines those parameters of the ADSL with an extended upstream bandwidth system that are unique to an ADSL service that is frequency division multiplexed with basic telephone service.
  • Annex-L: This annex defines those parameters of the ADSL system that are unique to a reach-extended ADSL2 service that is frequency division multiplexed with basic telephone service.

What is Annex-M?

  • This annex-M is an annex of the G.992.3 standard that extends the upstream bandwidth. This extension is achieved by doubling the upstream frequency range. With this feature, service providers can provision symmetric data rates for ADSL2 and ADSL2+ services with data rates up to 2 Mbps.
  • The ADSL2+ standard (ITU G.992.5) doubles the bandwidth used for downstream data transmission, effectively doubling the maximum downstream data rates, and achieving downstream data rates of up to 24 Mbps and upstream data rates of up to 1.5 Mbps. The exact data rates vary depending on the distance from the DSL access multiplexer (DSLAM), DSLAM type, line card and chipset, and firmware, noise profile, quality of copper, etc. The reach-extended ADSL2 standard (G.992.3) Annex L increases performance on loop lengths greater than 16,000 feet from the Central Office. The Annex M for G.992.3 (ADSL2) and G.992.5 (ADSL2+) was consented on October 2003. The Annex M for for G.992.3 (ADSL2) and G.992.5 (ADSL2+) contains PSD Masks for new ADSL2 service over POTS that increases the upstream data rates by doubling the number of US tones to 64. As a result, Annex M provides higher upload speeds for users by doubling the upstream data rate (when compared to Annex A) under certain loop and noise conditions.
