Operation
There are several important aspects regarding the operation of the TUPP 2488. These are
described in detail in the following sections. Example configuration scripts are available in the
TUPP 2488 Configuration Guide.
Configuration Options
The TUPP 2488 carries SDH tributary units (TUs) in an STS-48/STM-16 or four
STS-12/STM-4 byte serial data streams. The four streams are each carried in four slices each
containing payload processing blocks. Each slice consists of seven blocks: tributary pointer
interpreter (VTPI), tributary path overhead processor (RTOP), tributary trace buffer (RTTB),
tributary payload aligner (VTPA), SONET/SDH virtual container aligner (SVCA), tributary bit
error rate monitor (TBER), and the tributary alarm summary report block (TASR).
Along with the payload processing mentioned above, TUPP 2488 provides STS-1 level
switching at its line ingress input and line egress output. On the system side, TUPP 2488
contains eight OC-12 column granularity time switches in each direction. Next to these is an
OC-192 column space switch which takes information from both line and system side and also
sends information in both directions.
The TUPP 2488 processes High Order Pointer information on its Line Ingress and Transmits
High Order Pointer information on its Line Egress.
The TUPP 2488 device passes information on both the line and system side through serial CML
blocks. The line side can also work in parallel TelecomBus mode.
The applications of the TUPP 2488 device are facilitated by configuring it for the following:
•
•
•
•
There are a number of loopbacks and bypasses that may be used within TUPP 2488 for normal
operation and also to aid in debug.
OC-12#1 represents the Master OC-12 for TUPP 2488’s internal subsystems barring the System
CML. In the System CML where there are two sets of OC-48 buses, both OC12-#1 and
OC-12#5 are Master Streams.
