Abacus Product Family

Spirent Communications is first to market with an integrated IP Telephony and PSTN Telephony test

system in a single platform.

The Abacus Product Family provides a compelling value proposition by delivering

integrated functionality for IP Telephony and traditional PSTN Telephony

Abacus 5000•5 Easy Steps to Running a test

‘5 Easy Steps’ to configure and run a test using the Abacus 5000

1 2 3 45

1. Protocol Selection

- Circuit type, Channel type, Protocol Type

2. Phone Numbers

- Phone numbers for call routing

3. Channel and Path Confirmation

- Path confirmation type, Tone levels, Switch and Terminating Side variances

4. Partition and Timing

- Scripts to run on each group, and Call time parameters

5. Starting and Stopping a Test

Step 1A. Protocol Selection: Card

• Slot # in chassis

• Type of Card (*ICG3, *PCG3, ECG3)

• Signalling(SIP, H323, CAS, *ISDN, GR-303, SS7, V5.1, V5.2)

• Physical (*ICG, *T1, E1)

*Blue italicized word indicates selected option used in this example

Step 1A. Protocol Selection: CardContinued

• Side (Subscriber, Exchange, Switch)

• Law (u-law, A-law)

• Line (B8ZS, HDB3, AMI)

• Framing (ESF, D4, 2 Frame, 16 Frame, 16 Frame CRC)

Step 1B. Protocol Selection: Channels

Step 1C. Protocol Selection: ICG

• Configure ICG Setting Channel Quantity (Number of

Channels to be tested) – 23 Ethernet Mode to match the SUT

(Auto, Full 1000, Full 100, Full 10, Half 100, Half 10). The following are valid settings

Abacus SUT

Auto Auto

Auto HD

FD FD Subnet Mask of Host –

255.255.255.0 IP Address of on Host –

192.168.1.192 IP Address of Gateway on Host if

present– 192.168.1.1

Step 2A. Phone Numbers: PRI T1 Ex

1. Own Phone Numbers• Addresses of channels

associated with selected tab

• Available for subscriber, exchange, or switch channels

• One phone number is associated with each channel on Abacus 5000

• Sequential, 4155551001

2. External Phone Numbers • Destination numbers that will

be dialed by the associated channels

• Available for subscriber or exchange channels

• One phone number is associated with each channel on Abacus 5000

• File, Trunkgateway.phn (Phone Book)

Step 2A. Phone Numbers: PRI T1 Ex Continued

1. Select Phone Book type: Sequential or File

Sequential Phone Numbers -- specify start number

File --Used for non-sequential phone numbers, multiple area code, special IP Addressing.

2. Defines how each number applies to each line

Each channel – Separate phone number for each Channel

Each Circuit – Same phone number for entire circuit (Hunt Group)

3. Put checkmark if duplicate phone numbers allowed in files (e.g., for ACD groups)

Step 2B. Phone Numbers: SIP

Own Phone Numbers Addresses for Abacus SIP

endpoints associated with selected tab – Sequential user name 4085551001

External Phone Numbers Addresses that each SIP endpoint will call

during a test – Sequential user name 4155551001same IP, 192.168.1.193

Step 3. Channels: Path Confirmation

• Checks for continuity of speech path

• Five methods of Path Confirmation provide choice of schemes for each interface (Select one scheme)

– Tones

– 3-tone – 404 Hz, 1004 Hz, 2804 Hz

– Resilient – Measures Minor Interruptions in Test Tone

– Digital (PRBS) – 2 11 -1 = 2047 Pattern, 2 15 -1 = 32767 Pattern

– QoS

– PSQM / PSQM+ (ITU P.861)

– PESQ / PESQ-LQ (ITU P.862)

– Estimated MOS, JMOS, and R-Factor

– Packet

– Voice (Wav Files)

– Video (H.261 and H.263)

– Fax and Modem

Step 3A. Channels: Path Confirmation, PRI T1 or SIP, Basic

Available Options• None• Physical Address• Tones

• 3-tone – 404 Hz, 1004 Hz, 2804 Hz

• Resilient – Measures Minor Interruptions in Test Tone

• Digital PRBS (Pseudo Random Bit Sequence)

211 -1 = 2047 Pattern

215 -1 = 32767 Pattern

Note: In this example no options are selected on the Basic tab. Options are selected on Advanced tab.

Select Apply to all after selection is made

Step 3A. Channels: Path Confirmation, PRI T1 or SIP, Advanced -- Continued

Select wave file to be sent – f_nice

Select wave file to be sent Simplex (one direction at a time) or Duplex (both directions at the same time)

Select Apply to all after selection is made

Select Voice QOS Measurement Method – QOS, PSQM

Packet available only on ICG

Step 3B. Channels: Tones, PRI T1 or SIP

• Determines the criteria that tones sent from the SUT must meet in order for Abacus to recognize them

• Determines the signal characteristics of tones sent by Abacus to the System Under Test

• Default values are selected

Step 3D. Channels: QOS

Specifies Threshold for PSQM and PESQ Measurement – 4.0, 1.0

Step 4A. Partition and Timing: Association Continued

•Channel configuration is how the channels of a set are assigned in terms of originate and terminate channels

–Originate Channels are designated by ‘O’

–Terminate Channels are designated by ‘T’

– SIP Side – all originate

–PRI T1 – all terminate

Step 4B. Partition and Timing: Timing and Scripts

Timing Parameters

•ST: Start – 10s

•SS: Start to Start – 3s

•CL: Call Length – 60s

•IC: Inter-Call – 20s

•CC: Call to Call – 80s

•BHCA: Busy Hour Call Attempts

Step 4B. Partition and Timing: Timing and Scripts – Continued

Abacus ‘Help’ provides details for partition and timing setup.

Step 4B. Partition and Timing: Timing and Scripts – Continued

• Default Scripts are provided – A call B (SIP) and confirms for Call Length

•A script consists of one or more actions that are created or edited in the Scripts Management window

•Select Script to open Script Management window

Step 5A. Starting and Stopping a Test:Set Test Duration

• Continuous (until user stops)• Run for Hours/ Minutes• Run Until Date/ Time• Run for X Number of Scripts

Test Duration

Step 5B. Starting and Stopping a Test: Starting the Test

Successful Compilation; Start of Test

•All Scripts and Parameters Compile when the test is started

Start Test

Step 5C. Starting and Stopping a Test: Stopping the Test

• Start time and date• End time and date• Test duration• Script per channel counter• Channels Status

After the test has stopped

Stop Test

Immediate StopTest Status
