The CAME can be configured, operated, and tested using six Request Commands. Each
Request Command is a combination of various write and read commands transmitted via the
Data bus of the CAME. The Address bus selects the Request Commands. The data flow for
writing the search pattern into the CAME is such that the Local Connection Identifier (LCI)
defines the address of the memory where the Port Number (PN), VPI, VCI, and the two auxiliary
bits P_IP and VCON are stored. The CAME is operated inversely for cell processing. In the case
of cell processing, the PN, VPI, and VCI address the memory in which the LCI is stored. As well
as the LCI being transmitted to the ALP, a search report is also transmitted. Request Commands
1 and 2 are activated by the ALP during cell processing. Request Commands 3 through 6 are
activated by the microprocessor via the ALP because the CAME has no microprocessor
interface. All six Request Commands are described in the following sections.

Request Command number 4 should be used for the set up and release of a connection. First,
the LCI (14 bits) and the two auxiliary bits VCON and P_IP are written into the Write Data
Register and Address Register via the Data bus. Subsequently, the PN, VPI, and the VCI are
written into the Write Data Register. Within the 16-bit word, any subdivision by the PN and VPI
is allowed. The LCI of the Address Register defines the address of the memory in which the
contents of the Write Data Register are written. After writing the entry into memory, status
information on the current request is stored in the Status Register. The Status Register is read
out at the end of each request.
