Verify proper network routings
and signal delays
The 2207 quickly and effectively
measures the quality of voice
transmissions on the network circuit
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)
