cards, any number of cards can be cascaded as long as the maximum reach between any two is not
exceeded. This is because any time the signal is demultiplexed, the jitter is eliminated as a limiting
factor.
The maximum reach between one transponder and the other must be halved if a Y cable is used. For more
information on Y-cable operation, see the
16.12 Termination Modes
Transponder and muxponder cards have various SONET and SDH termination modes that can be
configured using CTC (see

Description
All the bytes of the payload pass transparently through the cards.
The SONET Transport Overhead (TOH) section bytes and the SDH
regenerator section overhead bytes are terminated. None of these section
overhead bytes are passed through. They are all regenerated, including
the SONET TOH section data communication channel (SDCC) bytes and
the SDH data communications channel regenerator (DCCr) bytes. In the
section termination mode, the SONET TOH line and SDH multiplex
section overhead bytes are passed transparently.
In line termination mode, the section and line overhead bytes for SONET
and the overhead bytes for the SDH multiplex and regenerator sections
are terminated. None of the overhead bytes are passed through. They are
all regenerated, including the SONET SDCC and line data
communication channel (LDCC) bytes and the SDH DCCr and data
communications channel multiplexer (DCCm) bytes.
All of the client bytes of the clients passes transparently through except
the following: B1 is rebuilt, S1 is rewritten, A1 to A2 are regenerated, and
H1 to H3 are regenerated.
The SONET TOH section bytes and the SDH regenerator section
overhead bytes are terminated. None of these section overhead bytes are
passed through. They are all regenerated, including the SONET TOH
section DCC bytes and the SDH DCCr bytes. In the section termination
mode, the SONET TOH line and SDH multiplex section overhead bytes
are passed transparently.
In the line termination mode, the section and line overhead bytes for
SONET and the overhead bytes for the SDH multiplex and regenerators
sections are terminated. None of the overhead bytes are passed through.
They are all regenerated, including the SONET SDCC and LDCC bytes
and the SDH DCCr and DCCm bytes.
