Features And Scaling - Avaya 8800 Planning And Engineering, Network Design

When connecting 10 GbE modules back-to-back, or through metro (OM5200) or long haul (LH
1600G) dense Wavelength Division Multiplexing (DWDM) equipment, you can use the timing
combinations of internal-internal, line-internal, or internal-line on both ends of the 10 GbE WAN
connection. In these scenarios, at least one of the modules provides the reference clock. DWDM
equipment does not typically provide sources for timing synchronization. For DWDM, Avaya
recommends that you avoid using a line-line combination because it causes an undesired timing
loop.
The following table describes the recommended clock source settings for 10 GbE WAN interfaces.
Use these clock settings to ensure accurate data recovery and to minimize SONET-layer errors.
