Naming Conventions
1650 SMC and 1660 SM
• 16 – Type of Alcatel equipment i.e 16 means transmission
equipment
• 5 & 6 – Highest transmission rate
i.e - level 5 corresponds to STM-4
- level 6 corresponds to STM-16
• 0 – Family
i.e – level 0 corresponds to OMSN (Optical Multiservice Node)
• S- Synchronous
• M- Multiplexer
• C- Compact
Note: 1660SM release 5.4 can support STM-64 (Infocom’s case)

Numbering Plan
From xx yz ab, one can deduce the following;
xx Type of equipment
• 13 management equipment (e.g. 1353 NM, 1354 RM)
• 16 transmission equipment (e.g. 1678 MCC, 1660 SM)
y Level of the highest transmission rate:
• Level 1 corresponds to 2 Mb/s (PDH)
• Level 2 corresponds to 8 Mb/s (PDH)
• Level 3 corresponds to 34/45 Mb/s (PDH)
• Level 4 corresponds to 140 Mb/s (PDH) or 155 Mbit/s (STM-1)
• Level 5 corresponds to 622 Mb/s (STM-4)
• Level 6 corresponds to 2.5 Gb/s (STM-16)
•

Numbering Plan…..CONT
• Level 7 corresponds to 10 Gb/s (STM-64)
• Level 8 corresponds to 40 Gb/s (STM-256)
z Level of the lowest transmission rate:
The fourth number can have several other meanings. Examples:
• 1660 SM: 0 indicates OMSN (Optical Multi Service Node)
• 1662 SMC: 2 indicates “Compact” OMSN
• 1678 MCC: 8 indicates future transmission rate (40 Gb/s)

OMSN Applications
9

Applications…cont..
OMSN can be used in;
• Ring topology
• Linear Topology
• Meshed Topology
• Point-to-Point
Note: OMSN is compliant with the most recent ITU-T and ETSI
for SDH equipment
*ITU-T – International Telecommunication Union –
Telecommunication Sector
*ETSI - European Telecommunications Standard Institute

Ethernet/MPLS service application
11

Ethernet service application..cont
12
• 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.

Alcatel Management Hierarchy
13

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
14

Hierarchy in Detail
15
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

Hierarchy in Detail

1354 BM-Eth (Broadband Management Ethernet)
• For Ethernet Services
1354 BM-ATM (Broadband Management ATM)
• For ATM Services

Telecommunication Management
Network
17

TMN- Details
18
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.

TMN- Details
19
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.
