The Cisco® 10000 Series 4-Port Half-Height Channelized T3 Line Card sets a new standard for high availability, scalability, and performance in the T1 and T3 aggregation market. This half-height line card supports four T3 physical connections (eight per Cisco 10000 line-card slot) with each T3 capable of supporting a full "clear-channel" DS-3 or DS-3 Channelized down to DS-1 or N x DS-0.

Product Overview

Coupled with native edge-aggregation services such as high availability, Multiprotocol Label Switching (MPLS), and quality of service (QoS), the Cisco 10000 Series 4-Port Half-Height Channelized T3 Module provides a comprehensive set of enhanced aggregation services, including higher port density per Cisco 10000 line-card slot, 1:1 line-card failover protection through Y-cables, and enhanced bit error rate testing (BERT) and loopback testing capabilities.
Using channelized interfaces to receive multiplexed T1 circuits on a single pair of coaxial cables, service providers can save dramatically on power, floor space, local-loop charges, and equipment costs. The Cisco 4-port half-height CT3 module can accept both clear-channel T3 traffic and multiplexed circuits from T1 and N x DS-0.
With this combination of features and performance, Cisco Systems ® provides a versatile interface for an upgrade to the advanced network architectures provided by Cisco 10000 Series routers. Service provider points of presence (POPs) can use the 4-port half-height CT3 line card to enable rapid, efficient addition of circuits where density, performance, and high availability are required.

Applications

The Cisco 10000 Series 4-Port Half-Height Channelized T3 Line Card is ideal for several applications, including:

• Service provider edge offices or data centers aggregating circuits from multiple customer sites and locations to provide direct Internet access and other T1-related services

• Cell site aggregation for mobile wireless providers offering high-speed wireless data connections as an alternative to DSL or cable broadband access

• Cisco Broadband Local Integrated Services Solutions for T1 (BLISS)-The Cisco BLISS framework provides the network foundation and call control and application intelligence to deliver integrated data and voice services over a single connection for small and medium-sized businesses (SMBs). It can support Metro Ethernet, DSL, cable, and T1 access. The Cisco 10000 Series has been tested and approved for the T1 aggregation portion of the Cisco BLISS solution and enables several providers to offer the services that SMBs require.

Key Features and Benefits

The 4-port half-height CT3 line card delivers numerous new features to the ESR 10000 Series Router:

• 4-port half-height form factor-The line card adds 2 ports per Cisco 10000 line-card slot, while providing the ability to add new ports in lower increments, reducing costs and saving valuable POP real estate.

• 1:1 line-card redundancy-Failover protection is provided within a single Cisco 10000 line-card slot in case a CT3 line card fails. Two line cards and 8 BNC Y-cables are required to support 1:1 redundancy: one as the working or active module, the other as the protect or standby module.

• Enhanced testing capabilities-These capabilities include the following:

– New BERT patterns (3-in-24, 1-in-8, and 2-in-8)

– Support for up to 12 simultaneous T1 BERTs (limited to six under the first two T3s and six under the second two)

– Addition of "show BERT" command

– Support for transmission of 2-in-5 and 3-in-5 inband remote loopback commands in Extended Super Frame (ESF) and SF modes (module will not respond to these in-band commands)

– A wide range of troubleshooting tools to ensure that customer connections are configured and operating per service provider specifications

• 256 channels per port-The 4-port half-height CT3 module doubles the number of available channels per port when compared with the 128 channels per port available on the 6-port CT3. Ports 0, 1, and 2 support 256 channels, and port 3 supports 255, giving service providers additional flexibility when adding new customers and services to their existing network. Note that the last port supports only 255 channels, for a line-card total of 1023 channels.

• T1 status LEDs-The addition of T1-level Alarm and Loopback LEDs provides fast, local fault indication when an alarm condition exists on any one of the 28 T1s contained in the DS-3 signal.
