Applications
The 2207 is designed to simplify testing of today’s complex networks by adding the key functionality required to ensure
performance of digital wireless networks. Programmed with highly integrated applications for in-service and out-ofservice testing, the 2207 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, often 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 2207 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 testing
patterns such as QRSS, the 2207 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
The 2207 qualifies of fractional T1 service to verify proper network routings and signal delays ensuring 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 2207 can check and verify individual
channels without disrupting network traffic. Transmitting and measuring tones on an individual PCM channel
utilizing the 2207’s in-service channel access affects only the channel under test and provides a further level of
performance analysis without impacting other revenue-generating channels. The 2207 provides TIMS measurements
such as:
• Level
• Frequency
• Signal to Noise Ratio
• Noise (C-Message and C-Notch filters)
