• Ethernet frames are mapped in SDH VC (single or concatenated VC-12, VC-3, VC-4) and transported over SDH network. A VC can be used either for a single Ethernet signal or for a number of Ethernet signals.

• In order to accomplish a pure transport of Ethernet signal, Ethernet cards are only required in the “end” NE (i.e. the nodes which are connected to routers or switches); the intermediate NE switches the VC. Otherwise, if the Ethernet signals are to be manipulated (aggregation, filtering,…) in the SDH network, Ethernet cards are required in the intermediate NE, too.

• The Ethernet services can be realized by means of Ethernet cross-connections or by enabling the Ethernet bridge function supported by the Ethernet cards.

Hierarchy in Detail

NE: Network Element

• OMSN and other Network Elements are located in this layer (figure shows only SDH Q3 NEs)

ECT: Equipment Craft Terminal

• All different kinds of Network Elements can be managed locally, depending on the type of NE and the type of local management interface operation

• OMSN, WDM, Microwave and Submarine are using the same platform 1320 CT based on Windows PC

• 1641 SX and 1674 LG (Lambda Gate) use a CT based on HP Unix Hardware

• 1678 MCC uses a 1320 CT based on Windows 2000 / Windows XP platform

EML (Element Management Layer): 1353 NM (Node Manager)

• Handles the physical configuration of the network resources

• Collects and processes the alarms emitted by the Network Elements to inform the operator about necessary actions

• Collects performance data of the Network Elements to allow preventive maintenance

NML (Network Management Layer): 1354 RM (Regional Manager)

• Sets up (protected) end-to-end paths at VC level: from VC-12 to VC-4; concatenated, too.

• Optimizes the use of the network resources, correlates performance data to paths

The management of the NE is performed by:

• Craft Terminal (CT)

• Operation System (OS) made up of one or more workstations,

whose function is network management.

• Further it permits the connection to the Telecommunication

Management Network (TMN).

• Only one Operation System can control a NE at the same time.

Craft Terminal interface is an EIA-RS232 type (F interface). It can be:

• local, connecting the Craft Terminal via the F interface.

• remote, from another SDH equipment or SDH gateway of the

network where a Craft Terminal is connected (to the F interface),

addressing the actual equipment. In this case the management

information is transported by the SDH network, using DCC bytes

(Qecc link), or routed by a LAN.

• When Remote Craft Terminal option is used, a max of 32

equipments are manageable by means of one F interface.
