You can use a short crossover cable with a straight-through cable adapter to connect to a
straight-through cable. Do this to convert a straight-through cable to a crossover cable.
T1 SFP—default settings
The Ethernet Routing Switch 5000 Series switches automatically configure the following T1
SFP parameters after the system powers up:
• Transmit Line Build Out (TLBO): set according to cable length.
• Framed or Unframed: Insert framing word into the frame (1 bit for each T1 frame) or do
not insert framing word into the frame.
• Line code: Binary 8 Zero Substitution (B8ZS) or Alternate Mark Inversion (AMI).
• Clock: Use Rx clock or internal clock for Tx clock (Avaya recommends internal clock for
Tx clock).
• Framing: D4 or Extended Super Frame (ESF), depends on the framing word required by
the T1 equipment at the far end.
