Slide 2
Why you require a transmission system? Between exchanges
dedicated media is expensive. Therefore a system is required
(called transmission system) which is able to carry the bulk
traffic via a single media.
Slide 3
Voice Frequency ranges upto 4 Khz Sampling the Voice Signal @ 8
Khz (Double the Max. Frequency)=8000samples/s 8 bits per sample
Digital Bit Rate: 8Kbps X 8 = 64 Kbps BUILDING UP THE BASE STREAM
(2MB)
Slide 4
BUILDING UP THE BASE STREAM (2MB) One sample duration (approx)
= 4 s Duration between samples = 125 s
Slide 5
BUILDING UP THE BASE STREAM (2MB) 30 Voice Channels @ 64 Kbps
One channel for Frame (64 Kbps) One channel for Signaling (64 Kbps)
Total number of Channels = 32 Bit Rate: 32 X 64 K= 2048 Kbps(2Mb

SDH Network Elements Regenerators Terminal Multiplexers
Add-drop Multiplexers (ADM) Multiple Add drop Multiplexers (MADM)
Digital cross connects
Slide 12
Regenerators whenever transmission over 50 km They terminate
and regenerate the optical signal n n i/p signal Regenerated o/p
signal
Slide 13
Regenerators..
Slide 14
Terminal Multiplexer (TM) Accept a number of tributary signals
multiplex them to appropriate optical/electrical aggregate signal
One line port To create Linear topology Line port Tributary ports N

Slide 15
Terminal Multiplexer (TM).. Input is low bit rate PDH or SDH
signal Output is high bit rate SDH signal
Slide 16
Linear Topology using TM Here n can be STM -1,STM-4 or SRM-16
Ring topology not possible using TM Only point to point linear
topology possible For that we need ADM or MADM Line port n n TM at
Alleppey TM at Ernakulam n n n n
Slide 17
Add Drop Multiplexer (ADM) Here n can be STM -1,STM-4 or SRM-16
Ring topology & point to point linear topology is possible
using ADM Can be operated in a throughmode fashion Line port 1Line

Add Drop Multiplexer (ADM)...
Slide 20
Digital Cross Connect (DXC) Here n can be STM -1,STM-4 or
SRM-16 Mesh Topology also possible using DXC DXC STM-N
Slide 21
Digital Cross Connect (DXC)... Input : many STM- N signals
Output: many STM-N signals
Slide 22
Multiple-Add Drop Multiplexer (MADM ) Equipment used to Add
(Input) Drop (Output) Mux - Demux and cross connect tributaries
(O&E) of different types and data rates. An actual Hardware
Software extension of existing ADM
Slide 23
Comparison between ADM and MDM MADM is an Improved (Hardware
and Software) Version of ADM ADM MADM 2 Number of STM 16 Line ports
Available. Hence Only Single Ring Configuration Possible 4 Number
of STM 16 ports. Double Ring Configuration within single equipment.
Hence Ring to Ring connectivity is possible without physical BUP,
traffic interruption is less Less Number of InterfacesMaximum
Number of Optical and Electrical Interfaces available Ethernet
support is very minimalWide range of Ethernet support including GbE
Ports

Add-drop Provisioning Provisioning of traffic in an ADM or MADM
is by adding and droppping using crossconnections Add-drop
provisioning is typically done by the network management
