Applications
The 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 2209 tests at both the pipeline and service levels to ensure that your network
is performing as advertised. Applications include:
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, 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 2209 provides the capability to monitor and perform BER testing
in both directions of a circuit simultaneously. The use of standard or user-programmable loopcodes to loop-back
network equipment allows for further sectionalization of network troubles. In addition to commonly used BER
patterns such as QRSS, the 2209 also offers several industry-recommended advanced stress patterns, including 55 Octet
and T1 Daly to ensure network performance.
Advanced timing analysis allows the technician to pinpoint signal delays, timing slips, and mismatches between 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 quickly and effectively measure the quality of voice transmissions
on the network circuit is required. By monitoring data or signaling bits, the 2209 can check and verify individual
channels without disrupting network traffic. Transmitting and measuring tones on an individual PCM channel
utilizing the 2209’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 2209 provides TIMS measurements
such as:

• Level
• Frequency
• Signal to Noise Ratio
• Noise (C-Message and C-Notch filters)
The 2209 quickly and effectively
measures the quality of voice
transmissions on the network circuit
