FST-2209 TESTPAD
The FST-2209 Module provides a full range of signal, alarm, and timing test
functions to ensure proper performance at the physical level of T1 and T3
network connections. It also offers the ability to place, receive and monitor voice
calls on PCM-based and ISDN PRI trunks. With the automated T1 BER testing in
the new TestMATE option of the FST-2209, both experienced and novice
technicians can install and maintain T1 networks quickly and accurately.
The functions of the FST-2209 include:
– DS1 signal analysis and BER testing with standard and advanced stress patterns
including 55 octet and T1-DALY
– Dual DS1 receivers for in-service monitoring and drop-and-insert testing
– DS3 BER testing analysis with patterns for both M13 and C-bit framing
– DS1 channel drop from a DS3 signal for testing or monitoring
– Monitoring, placement, or receipt of calls over T1 voice trunks and analysis
signaling bits
– Transmission and measurement of tones on individual PCM channels
– ISDN PRI call placement and receipt, backup D-Channel and NFAS testing,
and layer 3 (Q.931) results
– VT100 emulation for equipment configuration and results monitoring
The FST-2209 is designed to simplify testing of today’s complex networks.
Programmed with highly integrated applications for in-service and out-of-service
testing, the instrument tests at both the pipeline and service levels to ensure that
the network is performing as advertised.

Applications
– Isolate and troubleshoot physical layer problems associated with data or other
advanced services without taking channels out of service
– Verify proper network routings and signal delays to ensure all fractional T1
channel signals are terminated properly and with the correct timing
– Monitor network voice quality and signaling
– Test the ability of a PBX/switch to handle incoming calls
– Verify or troubleshoot ISDN PRI service by placing and receiving calls and
analyzing decodes
– Qualify DS3 circuits with an array of BER testing patterns
– Analyze DS1 tributaries at DS3 access points
– Sectionalize repeated T1 and HDSL circuits with embedded 16-bit smart
repeater and HDSL loopcodes
DS1 physical layer testing
Whether provisioning or troubleshooting T1 service, the first step is to verify
proper circuit operation throughout the network by testing the physical layer.
Typical requirements include BER testing and signal, alarm, and timing tests to
ensure proper performance of T1 network connections.
BER testing is typically conducted from the customer premises at an NIU or
HTU-R. To identify and sectionalize circuit problems from network equipment
faults, the FST-2209 monitors and performs BER testing in both directions of a
circuit simultaneously. The use of standard or user-programmable loop codes to
loopback network equipment allows technicians to further sectionalize network
troubles. In addition to commonly used BER patterns such as QRSS, the test
instrument also offers several industry-recommended, advanced stress patterns,
including 55 octet and T1-DALY to ensure network performance.

With its advanced timing analysis, technicians using the FST-2209 can pinpoint
signal delays, timing slips, and mismatches between the switch and remote
equipment.
Fractional T1 channel testing
Qualification of fractional T1 service requires the verification of network routings
and signal delays to ensure that all channel signals are terminated properly and
with the correct timing. In rural locations or on the outer reaches of the service
area, it is often critical to isolate single-circuit faults without disrupting the entire
line.
VF channel access and PCM TIMS
When problems with voice service arise, the ability to measure the quality of voice
transmissions on the network circuit quickly and effectively is essential. By
monitoring data or signaling bits, the FST-2209 can check and verify individual
channels without disrupting network traffic. Transmitting and measuring tones
on an individual PCM channel utilizing the test instrument’s in-service channel
access affects only the channel under test – providing a further level of
performance analysis without impacting other revenue generating channels. The
FST-2209 provides TIMS measurements that include:
–Level
– Frequency
– Signal-to-noise ratio
– Noise (C-message and C-notch filters)
The FST-2209 quickly and effectively measures the quality of voice transmission on the network circuit

Signaling testing
After the physical layer has been tested when provisioning or troubleshooting T1
voice trunks, it is also necessary to test the transmission and signaling
performance of the circuit. This testing verifies the ability of a switch or PBX
to handle incoming calls and ensures switch-to-switch communications. By
placing, receiving, or monitoring voice calls, connectivity can be verified. The
FST-2209 captures and displays digits, signaling events, and signaling bits to
provide a more detailed level of analysis.
The test instrument also displays physical layer results simultaneously, so
comprehensive testing of the voice trunk can be completed in a matter of minutes.
It provides signaling and voice results such as:
– DP, DTMF, MF digit recognition
– Interevent/digit delay measurements
– Event/digit duration measurements
– Speaker/microphone or handset functionality for checking voice integrity
– Signaling (ABCD) bits

DS3 testing
The first step in provisioning DS3 circuits is qualifying the physical layer. The
FST-2209 gives technicians the ability to qualify DS3 circuits with an array of BER
testing patterns for both M13 and C-bit framing and supports the verification of
frame synchronization on the circuit.
For more comprehensive and flexible testing, it is often also necessary to insert test
patterns or tones on single, multiple, or all DS1 channels within the DS3 circuit.
The FST-2209 DS3 BER testing measurements include:
– DS3 FEAC loopback codes
– Advanced stress patterns
– Signal level and frequency
– Insertion of logic and frame errors
A final level of analysis is provided by dropping DS1 channels from the DS3 signal
for testing or monitoring of the individual channels.
With the FST-2209 module, you can qualify DS3 circuits with a host of BER testing patterns

ISDN PRI testing
After verifying the physical layer, testing during the provisioning of ISDN service
is typically performed at the customer premises by emulating a TE device, such as
a PBX, to place and receive voice and data calls. Call status results and progress
reports provide an additional level of detail to ensure calls are successfully
established.
The reports are also useful for troubleshooting calls that are not established. When
multiple PRI lines are in use at the same location, it is often necessary to perform
backup D-channel and NFAS testing. By providing the user with simultaneous
results for physical layer (T1), layer 2 (LAPD), and layer 3 (Q.931) as well as plain
text decodes, the FST-2209 provides an efficient means to verify or troubleshoot
the ISDN PRI service. It can:
– Test multiple call types including voice, 56 K, 64 K, Nx56 K, Nx64 K, and H0 to
verify correct switch translations for both inbound and outbound calls
– Test data services (calls) using BER testing patterns
– Place and receive calls
– Receive call status results that provide a summary of calls
– Receive English decodes of layer 3 cause codes
– Receive full layer 3 (Q.931) decodes, with the ability to print
– Place and receive calls on either T1 (secondary or primary) for NFAS
configurations
– Switch from standby D-channel to in-service D-channel for verification of
D-channel backup operation in NFAS configurations
Verify or troubleshoot your customer’s ISDN PRI service using the FST-2209 module’s ISDN testing capabilities
