Tdm Configuration Options; Single Adm/Tm Mode - Eci Telecom XDM-100 General Description Manual

XDM® -100

3.3 TDM Configuration Options

The XDM-100's outstanding grooming capabilities (from 2 Mbps up to a full
2.5 Gbps in the same switching fabric) make it particularly suitable for traffic
adjustments and network expansions. This matchless combination shrinks the
amount of required network resources and reduces bottlenecks in metro-access and
cellular hub sites.
The platform features common I/O slots and hot-swappable modules for numerous
topology combinations, bitrates, protection schemes, and ports or protocols, for any
required service. Furthermore, it allows you to build-as-you-grow™, since the
elements are primarily deployed with minimal configuration and may be expanded
as network traffic demands grow.
The XDM-100 supports mesh, ring, star, and linear topologies. All system
configurations are controlled by a single network management system with
end-to-end service provisioning.
The XDM-100 can be configured to operate as a:
Single ADM/TM
♦
Multi-ADM/TM
♦

3.3.1 Single ADM/TM Mode

In the ADM/TM mode, the XDM-100 provides classic SDH/SONET multiplexing
functionality. It operates at the STM-1/4/16 or OC-3/12/48 line bitrates.
To operate the XDM-100 as a TM, a single aggregate is required. To operate it as an
ADM, two are used. Any service can then be provisioned by adding the relevant I/O
modules. In all modes, the XDM-100 matrix provides full nonblocking connectivity,
allowing high flexibility to traffic changes, efficient aggregation and network
utilization, and simplified network operation.
Although powerful enough in its initial configuration, a simple ADM/TM
implemented by the XDM-100 is future proof, with many expansion options:
When traffic demand grows, the ADM or TM can be upgraded from
♦
STM-1/OC-3 to STM-16/OC-48 on the same shelf
When new rings need to be deployed, the same element can be upgraded to a
♦
multi-ADM, closing several rings
When new bandwidth-hungry and data-oriented services are added, the
♦
simple addition of modules is sufficient
