Switch Manager

IDT77V550 is located on the IDT77V400 port to receive both signalling

cells and standard traffic cells. The Switch Manager does not have to be

connected to a Switching Memory port if it is only receiving the signalling

cells.

Features List

Interprets switch command cells from external work station

and loads the command into the IDT77V500 Switch

Controller

The Switch Manager has two cell streams which flow in opposite

directions, and can both interpret an incoming cell and generate control

cells as necessary. Figure 2 illustrates the basic block configuration of

the Switch Manager. The Data Path Interface (DPI) is used on both the

cell input and output ports of the IDT77V550. DPI is utilized on the

IDT77V400 to provide both reduced pin count per port and to offer

configuration flexibility.

Utilizes in-stream (in-band) signalling technique via the cell

stream into the Switching Memory

Can generate control cells to be sent back to the external

workstation

Executes three types of commands:

–

Writing data to Switch Controller

Reading data from Switch Controller

Reset operations

The IDT77V550 is capable of executing four basic types of

commands in the system:

Single +3.3V ± 0.3V power supply

Industrial Temperature (-40°C to 85°C) is available.

Writing data to the Switch Controller

Reading data from the Switch Controller

Description

Resetting the switch components

Reading Switch Manager version information

The IDT77V550 Switch Manager is a device developed to provide a

simple method of communication between an external workstation/

processor and the IDT77V500 Switch Controller. An In-Band signalling

technique is utilized to examine incoming ATM cells, determining if the

cell is a Command Cell for the Switch Controller, and loads the

command if appropriate. In the typical configuration (Figure 1), the

When writing information to the Switch Controller, the IDT77V550 will

store information needed to execute the command (up to 32 bytes) in

internal memory and perform the command across the Switch Controller

Manager bus. Likewise, for a read operation the information is received

from the Switch Controller, stored internally by the IDT77V550, and then
