4.6.2 BER Testing an EX7100: End-to-End
A) Connect the BERT equipment to the digital interface port of both EX7100 terminals
(G.703, or Sync Data) as required.
B) Set the sending BERT equipment to provide the clocking source for the test.
C) Set the interfaces of both EX7100 terminals to match the interface of the BERT
equipment - G.703 or V.35 (sync data) - as follows:
1) From idle, press ‘Enter’
Use the arrow keys to enter the First Level
password ‘1111’ and then press ‘Enter’.
2) Use the up and down arrows until the →
→→
→ is
next to Framer and then press ‘Enter’
3) Use the up and down arrow keys to make
sure the → is next to Interface and press
‘Enter.’
