Multi-Vendor OI
To support multi-vendor OI, DDM-2000 OC-12 R7.0 supports Target ID Address
Resolution Protocol (TARP) instead of Lucent Directory Service (LDS). DDM-2000 OC-
3 R13.0, FiberReach R3.0, and FT-2000 OC-48 R8.0 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.
DDM-2000 OC-12 R7.0 is developed to be compatible with any other-vendor NEs that
also support TARP, OSI, IAO LAN, and TL1/X.25 as specified in Bellcore GR-253. In
addition, DDM-2000’s TARP Manual Adjacency feature enables DDM-2000 to operate
in networks that include CMISE-based NEs which may not support TARP propagation.
DDM-2000’s compatibility with Tellabs TITAN
*
5500/S R5.0 DCS, with TITAN serving
as the TL1/X.25 GNE for DDM-2000 TL1-RNEs, has been confirmed through
cooperative joint testing. DDM-2000’s compatibility with some other-vendor NEs has
also been tested by independent third-parties.
Because DDM-2000 OC-12 R7.0 is intended to facilitate OS-based centralized
operations, and because TL1/X.25 OS access is the key standardized multi-vendor OI
application, the following Remote NE Status features are not supported in DDM-2000
OC-12 R7.0:
Remote office alarms
Remote CIT alarm reports
Remote user panel indications
TBOS telemetry
Parallel telemetry.
All of the above features depend on the proprietary exchange of information among
Lucent NEs in a subnetwork, specifically the communication of each remote NE’s alarm
status to other NEs. Although the Remote NE Status features were supported in
previous releases of DDM-2000, such Lucent-only operations features in multi-vendor
subnetworks would not include other-vendor NEs, due to the lack of applicable
standards, and thus would be incomplete.
