To support multi-vendor OI, the Alcatel-Lucent 1665 DMX supports Target ID Address Resolution Protocol (TARP).
TARP provides NSAP-TID translations and is the established multi-vendor standard for SONET NEs that support TL1 OS interfaces. Alcatel-Lucent 1665 DMX supports the TARP Data Cache (TDC) function to reduce the frequency of TARP propagation throughout the subnetwork and to improve performance.
Alcatel-Lucent 1665 DMX is developed to be compatible with any other-vendor NEs that support TARP, OSI, IAO LAN, and TL1 as specified in Telcordia ® GR-253. In addition, Alcatel-Lucent 1665 DMX's TARP Manual Adjacency feature enables it to operate in networks that include CMISE-based NEs which may not support TARP propagation. Alcatel-Lucent 1665 DMX supports user provisioning of several OSI parameters to allow users to adjust their operations network, if necessary. For example, to support Level 2 Routing in large networks, Alcatel-Lucent 1665 DMX supports user provisioning of NSAP area addresses and Level 2 Intermediate System (IS) functionality.
Alcatel-Lucent 1665 DMX's compatibility with other-vendor NEs may be tested by customers or independent third parties such as Telcordia ®.
