TNV1EC116, 16*STM-1 CES Interface Board

Applied to OSN 9800 U64/U32/U16 standard subrack

Support only one variant of S01, that is TNV1EC116S01


TNV1EC116 are applicable to the time division multiplexing (TDM) pseudo wire emulation edge-to-edge (PWE3) scenario. In this scenario, the PWE3 mechanism is used to simulate TDM services and connect the traditional TDM network to the packet switched network (PSN). It provides sixteen channelized STM-1 interfaces and supports CES/CEP services, another board EC404 which provides four channelized STM-4 interfaces and supports CES/CEP services.

Function Description
Basic function Processing capability Line-rate
Interface function Automatic laser shutdown Supported
Automatic loopback release on interfaces Supported
PRBSa Supports PRBS tests in framed or unframed mode for VC12 and VC4 channels in both the transmit and receive directions.
Traffic buffer time 50 ms
CES/CEP Supported service emulation modes CEP
Supports timeslot compression. In the case of CES services in CESoPSN mode, the board compresses 1 to 31 idle timeslots to conserve NNI-side bandwidth.
Supported clock mode Retiming mode
The jitter buffer time of the CES service can be set to a value ranging from 0.375 ms to 64 ms with steps of 0.125 ms.
The jitter buffer time of the CEP service can be set to a value ranging from 0.125 ms to 16 ms with steps of 0.125 ms.
The packet loading time can be set to a value ranging from 0.25 ms to 3 ms with steps of 0.125 ms.
Transparent transmission of SDH section overheads Supported in CEP mode but not in CES mode.
Transparent transmission of higher order POH Supported
Protection Supports LMSP/MC-LMSP.
a: The PRBS test function and the port loopback function cannot be both enabled simultaneously.
