Channel Interface Processor (CIP)

The CIP provides up to two channel-attached interfaces for Cisco 7000 series routers, eliminating
the need for a separate front-end processor. (See Figure 1-13.) The CIP interfaces are combinations
of a bus and tag (also called an original equipment manufacturer's interface [OEMI] and a parallel
I/O interface) adapter and/or an Enterprise Systems Connection (ESCON) adapter.
The bus and tag adapter is called the Parallel Channel Adapter (PCA) and the ESCON adapter is
called the ESCON Channel Adapter (ECA). The PCA and ECA connect directly to the CIP, and any
combination of the two adapters can be used.
Note
maintenance provider only.
While up to five CIPs can be installed in a Cisco 7000, we recommend that you leave one slot for a
WAN interface. The default CIP microcode boot image resides on a ROM in socket U37.
The supported processor input/output architectures for the CIP include ESA/390 for ESCON and
System/370, 370/Xa, and ESA/390 for bus and tag. The ESCON interface is capable of a data rate
up to 17 megabytes per second (MBps) and the bus and tag interface is capable of a data rate up to
4.5 MBps.

Multiple rate queues.
Reassembly of up to 512 buffers simultaneously. Each buffer represents a packet.
Support for up to 2,048 virtual circuits.
Support for both ATM Adaptation Layer (AAL) 5 and AAL3/4.
AAL3/4 is not supported in the initial release of IOS Release 10.0. AAL3/4 is supported with
Exception queue, which is used for event reporting. Events such as CRC errors are reported to
the exception queue.
Raw queue, which is used for all raw traffic over the ATM network. Raw traffic includes
operation and maintenance (OAM) cells and Interim Local Management Interface (ILMI) cells.
(ATM signaling cells are not considered raw.)
The ECA and PCA adapters can be upgraded or replaced in the field by a Cisco-certified
