Service providers face the challenge of meeting customer demand by building scalable, feature-rich networks that can deliver value-added services such as private IP connectivity; integrated data, voice, and video services; and tiered service offerings at all interface rates without compromising density. The Cisco® 12000 Series Channelized IP Services Engine (ISE) line cards provide a solution for the ever-increasing need for bandwidth and transmission capacity. These line cards take advantage of existing infrastructure, significantly lowering provisioning costs in terms of transmission and routing equipment. With the high-density aggregation offered by these line cards, service providers can build cost-efficient networks to serve large numbers of customers using telco infrastructure for IP access.
The Cisco 12000 Series 1-Port Channelized OC-12/STM-4 (STS3/VC4) ISE Line Card provides DS-0/DS-1 channelization (Figure 1).
The Cisco 12000 4-Port Channelized OC-12/STM-4 POS ISE Line Card provides channelization to DS-3 (Figure 2).
The Cisco 12000 1-Port Channelized OC-48/STM-16 POS ISE Line Card provides channelization to DS-3 (Figure 3).
