Function and Feature Description
Basic functions Transmits/Receives 20 Ethernet services, encapsulates and maps the Ethernet services into SDH signals, and forwards the SDH signals to the SDH plane for transmission. The maximum uplink bandwidth of the EMS20 board is 2 x 2.5 Gbit/s.
NOTE: The maximum uplink bandwidth of ports ip1 to ip10 or ip11 to ip20 on the EMS20 board is 2.5 Gbit/s.
When VC-12 signals are bound to a VCTRUNK, the maximum upstream bandwidth of the EMS20 board is 2 x 1.25 Gbit/s.
Services can be configured only to VCTRUNK1 to VCTRUNK64 for ports ip1 to ip10, and services can be configured only to VCTRUNK65 to VCTRUNK128 for ports ip11 to ip20.
Cross-connections are not supported between VCTRUNK1 to VCTRUNK64 and VCTRUNK65 to VCTRUNK128.
