2209
With the 2209, you can qualify
DS3
circutis with a host of BER
testing patterns
DS3 Testing
The first step in provisioning DS3 circuits is qualifying the physical layer. The 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 also often necessary to insert test patterns or tones on single, multiple,
or all DS1 channels within the DS3 circuit. The 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.
