ATM Basics
ATM is a packet-switched technology based on a 53-byte packet called a cell. Each
cell is divided into a 5-byte header and a 48-byte payload. The short, fixed length
cell reduces delay and jitter, allowing time sensitive information such as voice and
video to be transported along with data. There are various transmission media and
rates available with bandwidth measured in megabits to gigabits.
ATM Model
ATM is based on Broadband Integrated Services Digital Network, an extension of
ISDN. Similar to the OSI model, B-ISDN uses a seven-layer model. ATM redefines
the lower 3 layers into the Physical Layer, the ATM Layer and the ATM Adaptation
Layer.
" The Physical Medium sub-layer (PMD) interfaces with the physical medium.
" The Transmission Control sub-layer handles cell extraction from the data
stream and error checking.
ATM Headers
The ATM Cell has a 5-byte header, with the remaining 48-bytes left for payload
(data).

Cramsession: Cisco WAN Switching Certification
There are two standard headers. Cisco added an addition header type to allow for
advanced ATM features.
" User-to-Network Interface (UNI) header-specifies interface between a user
device and a network. Note: A user device is not just a computer interface.
It can be a router or switch as well.
" Network-to-Network Interface (NNI) header-specifies interface between two
networks. Usually a private ATM network and a public ATM network.
" STI header-used between to Cisco ATM switching nodes to allow advanced
network features.
" Flow Control (4-bits)-a UNI field for controlling access and flow control.
Usually all zeros, as there is no defined standards.
" Virtual Path Indicator (VPI)-identifies the path to be taken by the ATM cell.
" Virtual Circuit Indicator (VCI)-indicates the circuit number on the path.
" Payload Type Indicator (PTI, 3-bits)-the type of data being carried in the
payload. High order bit is 0 for user data and 1 for connection management
information, second bit indicates if there was congestion, and the third bit
show if user data is from customer premises equipment.
" Payload Class (4-bits)-STI field indicating classes of service and BPX switch
queues.
" Cell Loss Priority bit (CL)-indicates the cell may be discarded if congestion is
encountered.

ATM Addressing
" VCI identifies the circuit or connection.
" VPI identifies the virtual path.
" The path can be seen as a trunk that carries multiple circuits between
switches.
" VCI is 16-bits allowing 65, 535 circuit numbers. For the STI header VCI is 8-
bits for 256 circuits.
" VPI is 8-bits for the UNI header, 12-bits for the NNI header (4096 paths), and
10-bits for the STI header (1024 paths).
Cisco ATM Addressing
Three modes available depending on the hardware being used.

ATM Adaptation Layer
" ATM Adaptation Level (AAL)-used to convert data from various sources and
convert it to 48-byte segments that fit the payload of ATM cells.
" Four classifications of source traffic are outlined.
Traffic Class Class A Class B Class C Class D
Adaptation Layer

rate video
" Consists of Convergence sub-layer (CS) and Segmentation and Reassembly
sub-layer (SAR).
" CS receives data from the applications and sends it to the SAR to be
segmented into 48-byte blocks.
Quality of Service
These are some of the most important QoS parameters:
" Peak Cell Rate (PCR)-maximum rate a sender can send cells.
" Sustained Cell Rate (SCR)-required cell rate averaged over a long interval.
" Minimum Cell Rate (MCR)-minimum acceptable rate of cells per second.
" Cell Loss Ratio (CLR)-the fraction of cells not delivered or delivered late.
" Cell Transfer Delay (CTD)-time from source to destination (transmit time).
" Cell Error Ratio (CER)-fraction of cells delivered with incorrect bits.
" Cell Delay Variation (CDV or Jitter)-how regularly cells are delivered. Cells
from one conversation on a multiplexed connection may be delayed while
cells from another conversation are delivered.
" Cell Delay Variation Tolerance (CDVT)-amount of variation in cell
transmission times. Specified separately for PCR and SCR.
Service Categories
The ATM Forum specifies four service categories:
" Constant Bit Rate (CBR)-entire connection, from source to destination,
including intermediary switches, provides a set amount of bandwidth at all
times. Expensive because bandwidth is reserved even if it is not used.
" Variable Bit Rate (VBR)- guarantees an average bit rate over time, but allows
a higher peak bit rate, with no cells lost, for a certain amount of time each
minute. VBR is broken into two subclasses real time (rt) and non-real time
(nrt).
o rt-VBR is used for connections that require end-to-end timing, such as
voice or video connections using compression or noise reduction.

TM
Cramsession: Cisco WAN Switching Certification
o nrt-VBR can be used when timing relationships are not required, but
QoS is still needed.
" Available Bit Rate (ABR)-bit rate varies according to network conditions up to
a stated maximum. Source adjusts transmission rate due to network
information received from the network.
" Unspecified Bit Rate (UBR)-no set bit rate guarantee. Allows a transmission
rate up to a certain maximum, with no guarantee of cell loss or delivery.
Frame Relay Basics
Frame relay:
" Defines a connection between user equipment and a WAN, not the interface
or protocols of the WAN itself. Usually describes a LAN-to-LAN connection.
" A standard optimized for the transport of protocol-oriented data.
" Defines network paths using statistical multiplexing (creates virtual circuits).
" Does not allocate bandwidth until data needs to be transmitted.
" Combines packet switching and port sharing with time division multiplexing
circuit switching to allow multiple point-to-point permanent virtual circuits
over a single physical interface.
" Operates only on the Data Link and Physical layers of the OSI model. Routing
is general handled by the Network layer protocol.
Components of Frame Relay
" Committed Information Rate (CIR)-rate of data transfer under normal
operations. Generally the contracted rate from the public service provider.
CIR should never be set higher than the speed of the slowest physical
connection on a VC. CIR of 0=best effort.
" User-Network Interface (UNI)-describes a connection between user
equipment and a frame relay network. Usually, a router (DTE) and the
service provider.
" Network-Network Interface-describes connection between frame relay
networks.
" Local Management Interface (LMI)-monitors the status of DLCIs by
periodically polling the network. Can be used to exchange status information
between frame devices and the network. Also supports multicasting, global
addressing and flow control. Cisco switches support LMI.

Cramsession: Cisco WAN Switching Certification
" Bandwidth on Demand-capacity is provided as a PVC requires it up to the
maximum CIR.
" Flag-First and last byte of a frame, indicating the beginning and the end.
There may be only one flag between frames with the end flag of one frame
used as the start flag of the next.
" Data Link Connection Identifier (DLCI)-10-bit routing address of the PVC at a
particular UNI or NNI. Some DLCIs are reserve for signaling, management
and future use so only 16 to 1007 are used to address virtual circuits.
" Command/Response (C/R)-not used. Always set to 0.
" Extended Address (EA)-allows the header to be lengthened to 3 or 4 bytes
allowing a DLCI longer than 10-bits (more VC addresses).
" Forward Explicit Congestion Notification (FECN)-set to 1 by the frame network
when congestion is occurring on the packet forwarding direction of the frame.
" Backward Explicit Congestion Notification (BECN)- set to 1 by the frame
network when congestion is occurring on the reversed packet forwarding
direction of the frame.
" Discard Eligibility (DE)-set by the end node to indicate frames to be discard if
congestion occurs.
" Data-also called the information field. May be as large as 4,520 bytes, but is
more efficient with a size of less than 4k.
" Frame Check Sequence (FCS)-standard cyclic redundancy check that detects
bit errors in the frame.
Voice Basics
Human voice can achieve a frequency of up to 4000 Hz (usually between 300 to
3000 Hz).

Cramsession: Cisco WAN Switching Certification
Analog to Digital Conversion
" The coder-decoder (CODEC) converts analog voice signals to digital signals
using pulse code modulation (PCM).
" Multiple digital voice signals can be combined into a single channel using a
multiplexer (MUX). The process is called Time Division Multiplexing (TDM).
" A T1 connection can contain 24 channels or timeslots (called DS0s) of 64
kbps each.
" An E1 or J1 connection has 30 channels with two additional timeslots for
framing and signaling.
Sampling
" General rule is that sample rate should be twice the frequency of the signal to
be sampled (example: the human voice is capable of 4000 Hz so a sample
rate of 8000 samples per second would be required).
" Each sample is converted into a 8 bit word (8 bits per sample x 8000 samples
per sec = 64kbps).
Companding
" Part of the PCM process that determines the digital bits used to represent the
voice signals (whether the value of a sample is a digital one or zero).
" 2 companding laws:
o M-law (µ-law or mu-law): logarithmic method used in North America
o A-law: linear at lower levels and logarithmic at higher levels. Used in
Europe, Asia, Australia and South America.
" Different companding methods are not compatible (international voice traffic
requires conversion from one companding method to another).
Optimization
Adaptive Differential Pulse Code Modulation (ADPCM) Voice
Compression
" Uses fewer bits than PCM sampling because only the difference between
samples not the actual value of the sample amplitude is used.
" Defined in ITU-T G.726 recommendation.
" The following rates are available:
© 2001 All Rights Reserved  BrainBuzz.com

TM
Cramsession: Cisco WAN Switching Certification
o 40 kbps using 5-bit samples
o 32 kbps using 4-bit samples
o 24 kbps using 3-bit samples
o 16 kbps using 2-bit samples
" Does not use A-law or M-law coding.
" Not reliable for data or fax traffic above 4800 kbps.
Code Excited Linear Prediction (CELP) Compression
" Better than ADPCM at the same or higher data rate.
" Uses know characteristics of human speech to provide compression.
" Based on ITU-T G.729 standard.
" 8, 16, 24 and 32 kbps data rates are possible.
Silence Suppression
" Reduces bandwidth by stopping transmission during silent periods in the voice
signal.
" Dependant on language spoken, silence suppression can provide 60 percent
bandwidth reduction.
" Algorithm analyzes the signal to determine if a signal is voice or background
noise (based on known characteristics of human speech).
Signaling
Signaling occurs between a subscriber and a switch or a switch and a switch.
Signaling is the process of sending status and control information between network
elements. In voice communications, signaling is generally used to initiate a call or
connection.
Subscriber to switch signaling is used from handset to PBX and includes on-hook,
off-hook detection and dialing.
Switch to switch (or interswitch) signaling is used between the local exchange carrier
(LEC) and interexchange carrier (IXC) or between PBX and PBX (or switch).
Interswitch signaling is generally digital.
Two types of interswitch signaling:

TM
Cramsession: Cisco WAN Switching Certification
" Channel Associated Signaling (CAS)-signaling is sent on the same path as
the voice traffic with the signaling bits in a specified location on each
channel. Signal states are limited by number of bits used for signaling.
" Common Channel Signaling (CCS)-independent signal channels carry the
signal information for the voice channels. Generally more complex than CAS
and allows for more diverse signal states.
CAS vs. CCS signaling
CAS CCS
T1 interface Robbed bit signaling. Least Timeslot 24
significant bit of every sixth
frame is robbed.
E1 interface Timeslot 16 carries four Timeslot 16 as a clear channel
signaling bits per channel
J1 interface Timeslot 0 carries one signaling Timeslot 16 as a clear channel
bit per channel
Features Limited Many features available
Signal Rate Slow Fast
Versatility Limited number of signaling Wide variety of protocols available
states
Dialing Formats
There are two different dialing formats used by most switches:
" Pulse-each number dialed generates a number of pulses (dialing a three
would generate 3 pulses).
" Dual-tone Multifrequency (DTMF or tone)-each number dialed generates two
tones that uniquely identify the number.
Echo
Echo is caused by a difference in impedance between two network entities (usually
involving conversion from two-wire to four-wire transmission). This difference in
impedance causes reflections of the signal perceived as echo. Echo is always present
in a voice network. Echo is not a problem unless it reaches an unacceptable level
(delays of less than 250ms are generally considered acceptable).
Causes of delay:
" Compression-all compression algorithms have an inherent delay.
© 2001 All Rights Reserved  BrainBuzz.com
11
TM
Cramsession: Cisco WAN Switching Certification
" Packetization-delay caused as voice samples are collected until enough to
make up a packet are collected.
" Congestion-as a network becomes congested, packets can be delayed or
dropped.
" Silence Suppression-voice samples can be held until signal is determined to
be voice or noise.
" Transmission delays-transmissions over distance take time (packet-switched
networks generally have more delay than circuit switched networks).
An echo canceller can be added to reduce echo. An echo canceller compares
transmit and receive signals to measure loss and delay of the reflected signal and
subtracts the expected echo power level from the receive signal.
