Reason For Issue
This document replaces the 
DDM-2000 FiberReach Multiplexer Wideband/
Narrowband Shelf TARP Release 3.0 User/Service Manual, Volume I and Volume 
II, Issue 2
. Description, application, and engineering information has been 
updated/added to include FiberReach Multiplexer Release 4.0. Release 
descriptions are listed in Chapter 1, “System Introduction”.
Major changes in this issue are noted by bars (|) in the outermost margins. Major 
changes include adding information for the following: 
■
STS-3c 0X1 when shelf is equipped with 29G-U/29H-U OLIUs in Main slots 
and 22-type OLIUs in Function Unit slots
■
DCC provisioning on Main slots for FiberReach to allow a remote shelf to 
interconnect through its Main ring interfaces with a 1+1 linear extension on 
a host OC-3, OC-12, or OC-48 shelf
■
Provisioning of asynchronous CIT port to run TL1
■
Remote alarm status using AGNE and Alarm Group concept
■
29G-U OLIU 1310 nm long reach OC-12 circuit packs
■
29H-U OLIU 1550 nm long reach OC-12 circuit packs
■
22G4-U OLIU 1310 nm long reach OC-3 circuit packs
■
BBF6 T1EXT circuit pack with individual T1 facility loopback capabilities.
NOTE:
This manual covers software releases up to an including TARP Release 3.0 
and later. The impact of introducing TARP affects many areas of the 
document. Be aware that both TARP and the Lucent Directory Services 
(LDS) protocol operations are discussed and that some operations and 
features available in pre-TARP releases will no longer be applicable in 
FiberReach Multiplexer Release 3.0 and later.
Multi-Vendor OI
0
To support multi-vendor OI, DDM-2000 FiberReach Release 3.0 and later 
supports Target ID Address Resolution Protocol (TARP) instead of Lucent 
Directory Service (LDS). DDM-2000 OC-3 R13.0 and later, OC-12 R7.0, and FT-
2000 OC-48 R8.0 and later also support TARP; thus Lucent 2000 Product Family 
OI compatibility is still supported but not OI compatibility with previous releases of 
DDM-2000 and FT-2000. TARP is the established multi-vendor standard for 
SONET NEs that support TL1 OS interfaces.
