7 WAN Interface Sublayer (WIS) Description (QT2032 Only)
This section describes the function and extended features of the WIS block in the QT2032. The WIS block is
enabled and the chip will operate in WAN mode when LANMODE = 0. The WIS block can be bypassed by setting
MDIO register 2.7.0 to 0 or if LANMODE = 1. When bypassed, the QT2032 will be 10GE (or 10GFC) protocol
compliant.
7.1 WIS Transmitter
The WIS transmitter functionality is illustrated in Figure 10 and is fully compliant with IEEE 802.3-2005 Clause 50.
Additionally, extended features have been provided for APS Channel, synchronization status, line BIP-8 signal fail
& degrade, pointer justification event counters, 64-byte J1 messaging, and transport overhead (TOH) serial inter-
face. These features are described in Section 7.3, “Extended WIS Features,” on page 46.
7.1.1 WIS Frame
Figure 10 illustrates the structure of an STS-192c WIS frame, which is comprised of transport overhead and a pay-
load. The overhead fields are described in the following sections.
