Detailed Information

Channelized OC-12 line card

The Cisco 10000 ESR Channelized OC-12 Interface Module supports the highest-density DS1

connectivity in the industry. A fully configured Cisco 10000 ESR with six Channelized OC-12 line cards

and redundant uplink cards supports 2000 DS1 connections, and by configuring up to six

Cisco 10000 ESRs per 30" deep, seven-foot rack, in a back to back configuration, the Cisco 10000 ESR

solution supports more than 12,000 DS1 connections per rack. In addition to density and scalability, the

Cisco 10000 ESR Channelized OC-12 card provides the flexibility of supporting any combination of up to

12 DS3 connections, 336 DS1 connections, nxDS1 up to 24 DS0 channels per DS1, or 28 individual VT 1.5 channels,

up to a total of 768 channels per card (192 channels per STS-3). VT1.5 will be supported in a follow up maintenance release.

Customers have flexibility of mixing and matching virtually any combination of nxDS0s, DS1s, fractional DS1s,

or DS3s at the individual Channelized OC-12 card level. The Channelized OC-12 line card implements SONET automatic

protection switching (APS), which provides for a very fast Layer 1 switch over mechanism to support 1:1 redundant

transmission circuits

OC-12 ATM line card

The Cisco 10000 Edge Services Router (ESR) single-port OC-12 ATM interface line card provides OC-12 (622 Mbps SONET/SDH) uplink from an aggregation router to the ATM networks. While focused on intra-pop ISP router to router connectivity, the ESR OC-12 ATM line card also addresses applications which rely on broadband IP transport over ATM WAN's.This card receives and transmits ATM cells on the physical interface while transmitting and receiving packets from the backplane. The OC-12 ATM line card supports the following:

· SONET/SDH OC12 STS-12c/STM-4c framing format.

· Support for up to 2000 VCs per system

· Supports all 16 VCI and 8 VPI bits.

· Supports AAL5 data transport, F4 and F5 OAM cells.

· Support for MTUs of up to 9180 octets.

· Support for per-VC and per-VP traffic shaping for VBR circuits.

· Support for per-VC queuing, on nr-VBR VCs.
