Media Modules
Media modules belong to the Nways family and can be used in the 8265 switch to:
•
Send and receive data from an ATM subsystem in another 8265 switch
•
Attach high capacity workstations and servers that function in ATM mode.
The media modules interface to the 8265 switch by means of the Control Point and
Switch (CPSW) module. These modules process ATM cells of data by:
•
Checking their validity
•
Accessing the switching tables to locate the destination module
•
Preparing the internal ATM format required by the CPSW module
•
Sending the cells to the CPSW module.
The media modules support the following interfaces:
•
User-to-network (UNI)
•
Public User-to-Network (Public UNI)
•
Private Network-to-Network (PNNI)
•
Interim Inter-Switch Protocol (IISP)
•
VOID.
The UNI, IISP, and PNNI interfaces supported are defined in the following documents:
•
ATM User-Network Interface (UNI) Specifications V3.0, V3.1, and V4.0,
ATM Forum
•
ATM Interim Inter-Switch Signalling (IISP), ATM Forum
•
ATM Public Network-to-network Interface (PNNI) Phase 1, ATM Forum.
Table 6 on page 24 lists the media modules that can be installed in the 8265. For a
list of 8260 ATM media modules that can be installed, refer to page 71.
