Maintenance Description
9-6 Issue 3 June 2001
Multi-Vendor OI 9
To support multi-vendor OI, DDM-2000 OC-3 R13.0 and R15.0, and OC-12 R7.0
support Target ID Address Resolution Protocol (TARP) instead of Lucent Directory
Service (LDS). DDM-2000 FiberReach R3.0, 3.1, 4.0 and FT-2000 OC-48 R8.0,
9.0 and 9.1 also support TARP. The Lucent PF-2000 Product Family is not OI
compatible with Lucent TARP products. Both LDS and TARP are directory
services that provide NSAP-TID translations. LDS supports additional Lucent-only
features, but TARP is the established multi-vendor standard for SONET NEs that
support TL1 OS interfaces. DDM-2000 supports the TARP Data Cache (TDC)
function to reduce the frequency of TARP propagation throughout the subnetwork
and to improve performance. No DSNE concept is used in TARP.
DDM-2000 OC-3 R13.0 and R15.0 has been developed to be compatible with any
other-vendor NEs that also support TARP, OSI, IAO LAN, and TL1/X.25 as
specified in Telcordia 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 OC-3 R13.0 and R15
support user provisioning of several OSI parameters to allow users to adjust their
operations subnetwork, if necessary. For example, to support subnetwork
partitioning of large subnetworks, DDM-2000 supports user provisioning of NSAP
area addresses and level 2 Intermediate System (IS) functionality.
DDM-2000 OC-3 R13.0’s and R15.0’s compatibility with Tellabs
TITAN
*
5500
DCS R5.0, including TL1/X.25 OS access with
TITAN 5500 DCS serving as the
TL1-GNE for DDM-2000 TL1-RNEs, has been confirmed through cooperative
joint testing between Lucent and Tellabs. DDM-2000’s compatibility with some
other-vendor NEs has also been tested by independent third-parties such as
Telcordia on behalf of the SONET Interoperability Forum (SIF).
