Channel Interface Processor

The CIP for the Cisco 7000 with RSP7000 and Cisco 7500 series routers is designed for high-end network environments that demand high-performance, high-port density, and high-capacity solutions.

The CIP provides support for IBM ESCON and bus-and-tag parallel channel attachment using the following types of interfaces:

•ESCON Channel Adapter (ECA)

•Parallel Channel Adapter (PCA)

A single CIP can support up to two physical channel interfaces in any combination of either PCA or ECA. Each CIP is pre-configured with the appropriate channel adapters at manufacturing time.

The Cisco 7000 with RSP7000 and Cisco 7500 series routers support online insertion and removal (OIR), which allows you to install or remove CIPs while the system is operating.

Channel Port Adapter

The CPA is available for the Cisco 7200 series routers. The CPA expands the value of Cisco’s IBM channel solution by providing channel connectivity to mid-range mainframe configurations.

The CPA is a standard, single-width port adapter that provides support for IBM ESCON and bus-and-tag parallel channel attachment using the following types of interfaces:

•ESCON Channel Port Adapter (ECPA)

•Parallel Channel Port Adapter (PCPA)

Each CPA provides a single channel interface (with a single I/O connector) for Cisco 7200 series routers. In some situations, this eliminates the need for a separate front-end processor (FEP).

The only differences between CMCC software applications running on the CIP and a CPA are performance and capacity. The performance difference is based upon differences in the internal bus architecture of a CIP and a CPA, and the capacity difference is based on the difference in maximum memory configurations (128 MB for CIP and 32 MB for CPA). For more information about differences between the CIP and CPA, see the “Differences between the CIP and CPA” section on page 247.
