As a loop-optimized product, the DDM-2000 OC-12 Multiplexer allows operation
and maintenance of all remote DDM-2000 NEs in a subnetwork from a DDM-2000
in a central office. A subnetwork consists of NEs interconnected by optical lines
and/or an IAO LAN with the SONET data communications channel (DCC)
enabled. Similarly, a technician working at a remote site can gain access to the
central office (CO) DDM-2000 associated with that DDM-2000 OC-12 Multiplexer,
as well as with other remote DDM-2000 Multiplexers in the same subnetwork. The
DDM-2000 OC-12 Multiplexer uses the SONET DCC to provide CIT remote
access, remote software downloads, and OS remote access. The DDM-2000
OC-12 Multiplexer uses the International Standards Organization (ISO) compliant
open systems interconnection (OSI) protocol to communicate over the DCC.
Figure 9-2 shows the single-ended operations
*
(SEO) capability that provides
remote access to all DDM-2000 systems in a subnetwork from a single
DDM-2000 location. This minimizes technician travel because most maintenance,
provisioning, and administration can be performed on all DDM-2000 Multiplexers
in a subnetwork by accessing any DDM-2000 Multiplexer in the subnetwork. The
SEO capability is provided by the DDM-2000 Multiplexers regardless of the
subnetwork topology as long as DCC connectivity is available. The SEO (DCC)
capability can be disabled between DDM-2000 shelves to create network
maintenance boundaries (for example, interoffice applications) or for security
reasons.
DDM-2000 OC-12 supports Lucent Technologies 2000 Product Family OI with
DDM-2000 OC-3, FiberReach,
SLC-2000, and FT-2000. It also supports multi-
vendor OI in subnetworks with other-vendor NEs such as Tellabs
TITAN 5500.
See Section 2, "Applications," and Section 8, "Administration and Provisioning,"
for more information about OI.
*
The terms single-ended maintenance and single-ended operations (SEO) are synonymous
and have traditionally been used to refer to operations among DDM-2000 systems only.
Now that SEO is supported among the 2000 Product Family NEs as well as in multi-vendor
applications, the term operations interworking (OI) is more commonly used. OI among
multi-vendor NEs will be covered later in this chapter.
