Number of supported ATM
services
64
Encapsulates ATM VPC/VCC service to the PWE3 in the N-
to-1 (N≤32) or 1-to-1 format.
Encapsulates the ATM cells to the PW in the concatenation
and non-concatenation modes. The number of PW
connections that support the cell concatenation is 64, and the
maximum number of concatenated cells is 28.
ATM OAM on the UNI side
and NNI side
Supports the CC test.
Supports the LB test.
CES Number of supported CES
services
16
Supported emulation mode CESoPSN
SAToP
Supports the timeslot compression function. Provides the idle
64 kbit/s timeslot suppression function for the CES services
in the CESoPSN mode to save the transmission bandwidth.
Supported clock modes Retiming mode
Self-adaptation mode
The jitter compensation buffer time of the CES service can be
set. The jitter buffer time ranges from 0.375 ms to 16 ms, and
the step value is 0.125 ms.
The packet loading time of the CES service can be set. The
encapsulation buffer time ranges from 1 ms to 3 ms, and the
step value is 1 ms.
