Chapter 3 Overview of the ICS1893Y-10
ICS1893Y-10 Rev F 1/20/04
The ICS1893Y-10 is a stream processor. During data transmission, it accepts sequential nibbles from its
MAC (Media Access Control)/Repeater Interface, converts them into a serial bit stream, encodes them, and
transmits them over the medium through an external isolation transformer. When receiving data, the
ICS1893Y-10 converts and decodes a serial bit stream (acquired from an isolation transformer that
interfaces with the medium) into sequential nibbles. It subsequently presents these nibbles to its
MAC/Repeater Interface.
The ICS1893Y-10 implements the OSI model’s physical layer, consisting of the following, as defined by the
ISO/IEC 8802-3 standard:
•
•
•
•
The ICS1893Y-10 is transparent to the next layer of the OSI model, the link layer. The link layer has two
sublayers: the Logical Link Control sublayer and the MAC sublayer. The ICS1893Y-10 can interface directly
to the MAC and offers multiple, configurable modes of operation. Alternately, this configurable interface can
be connected to a repeater, which extends the physical layer of the OSI model.
The ICS1893Y-10 transmits framed packets acquired from its MAC/Repeater Interface and receives
encapsulated packets from another PHY, which it translates and presents to its MAC/Repeater Interface.
Note:
Physical Coding sublayer (PCS)
Physical Medium Attachment sublayer (PMA)
Physical Medium Dependent sublayer (PMD)
Auto-Negotiation sublayer
ICS1893Y-10 - Release
As per the ISO/IEC standard, the ICS1893Y-10 does not affect, nor is it affected by, the underlying
structure of the MAC/repeater frame it is conveying.
