Only TN55TTX supports ODUflex scheduling.
Customer Side Service Types	STM-64/OC-192: SDH/SONET service at 9.95Gbit/s 10GE LAN: Ethernet service at 10.31 Gbit/s 10GE WAN: Ethernet service at 9.95 Gbit/s OTU2: OTN service at 10.71 Gbit/s OTU2e: OTN service at 11.1Gbit/s FC800: SAN service at 8.5 Gbit/s FC1200: SAN service at 10.51Gbit/s Description: Only the TN55TTX supports access to OTU2/OTU2e/FC800/FC1200 services.
Cross-capability	Supports 10 ODU2/ODU2e/ODUflex signals to realize cross-scheduling of services through the backplane bus with the crossover board. Description: Only the TN55TTX supports ODUflex scheduling.
OTN Features.	Mapping processing meets ITU-T G.709 with ITU-T G.709 recommended frame format and overhead processing. ODU2/ODUflex layer: supports PM and TCM overhead processing, as well as non-intervention monitoring of PM and TCM. OTU2 layer: supports SM function.
ESC function	Supported when accessing OTU2/OTU2e services. Description: Supports ESC function for up to 8 channels.
PRBS Function	The PRBS function is supported on the client side. Description: The PRBS function is supported on the client side only when accessing STM-64/OC-192/OTU2/OTU2e services. The TN54TTX can only configure PRBS for one port at the same time. the TN55TTX has no such restriction.
LPT Function	The LPT function is supported only when the client-side service type is 10GE LAN.
