Chapter 8 Transponder and Muxponder Cards
8.17 SFP and XFP Modules
For TXP and MXP cards, adhere to the following conditions while DCC termination provisioning:
• For SDCC/RS-DCC provisioning, the card should be in the Section/RS-DCC or Line/MS-DCC
termination mode.
• For LDCC/MS-DCC provisioning, the card should be in the Line/MS-DCC termination mode.
For more information on enabling termination modes, see the procedures for changing card setting in the
“Provision Transponder and Muxponder Cards” chapter of the Cisco ONS 15454 DWDM Procedure
Guide.
8.17 SFP and XFP Modules
SFPs and 10-Gbps SFPs (XFPs) are integrated fiber optic transceivers that provide high-speed serial
links from a port or slot to the network. For more information on SFPs/XFPs and for a list of SFPs/XFPs
supported by the transponder and muxponder cards, see the Installing the GBIC, SFP, and XFP Optics
Modules in Cisco ONS Platforms.
In CTC, SFPs/XFPs are called pluggable port modules (PPMs). To provision SFPs/XFPs and change the
line rate for multirate PPMs, see the Cisco ONS 15454 DWDM Procedure Guide.
Table 8-39 Termination Modes
Cards Termination Mode Description
All TXP and MXP
cards, with the
exception of the
MXP_2.5G_10G
card (see next section
of this table)
Transparent Termination All the bytes of the payload pass transparently through the cards.
Section Termination The SONET transport overhead (TOH) section bytes and the SDH
regenerator section overhead (SOH) bytes are terminated. None of these
SOH bytes are passed through. They are all regenerated, including the
SONET TOH section DCC (SDCC) bytes and the SDH regenerator section
DCC (RS-DCC) bytes. In the section termination mode, the SONET TOH
line and SDH multiplex section overhead bytes are passed transparently.
Line Termination 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 DCC (LDCC) bytes and
the SDH RS-DCC and multiplexer section DCC (MS-DCC) bytes.
MXP_2.5G_10G
1
1. Clients operating at the OC48/STM16 rate are multiplexed into an OC192/STM64 frame before going to OTN or DWDM.
Transparent Termination All client bytes pass transparently except the following: B1 is rebuilt, S1 is
rewritten, A1 to A2 are regenerated, and H1 to H3 are regenerated.
Section Termination 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 RS-DCC bytes. In the section termination mode, the
SONET TOH line and SDH multiplex section overhead bytes are passed
transparently.
Line Termination 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 RS-DCC and MS-DCC bytes.
