2 x FE (Electrical) on main board is the default. By software key, this can be changed into 4 x GbE (10/100/1000Base-T)

2xSFP(GbE) can be set either Optically or Electrically. Same SFP type is required. LCT/NMS interface has NE 1 and NE2. These interfaces are to be used

for IDU-IDU back-to-back stacking. AUX interface can be used e.g. for taking in alarms of air-conditioners, doors etc. Sync. ETH Clock option module is mounted onto the main board for Sync ETH or

channelized STM-1.

*: Channel SeparationNote: Maximum throughput at 64 byte-passed rate based.

Available AMR operation mode

AMR is a technology to improve robustness mainly in the packet transmission environment by utilizing thermal threshold difference between modulation hierarchy such as QPSK and 256 QAM.

On the fine day, the operator can get the 220Mbps throughput over the link which is designed for 53Mbps throughput as illustrated in the figure.

iPASOLINK support hitless modulation switchover from 256QAM to QPSK as shown in table.

iPASOLINK XPIC (Cross Polarization Interference Canceller)iPASOLINK can double its transmission capacity up to 880Mbps in 56MHz bandwidth by adopting NECs state of the art XPIC technology. The additional required components for XPIC are;

Dual polarized antenna, Additional ODU, Associated IF cable kit, Soft-key upgrade in IDU.

(In case of iPASOLINK200, no cable connection is required at the front panel for XPIC )

- CIR / EIR/ CBS/ EBS committed / excess burst size

Egress QoS function, previous stage of adaptive modulation supports per-class queuing with strict priority and deficit round robin mechanism.

Each queue supports:- maximum rate shaping and minimum rate guarantee- weighted tail drop or WRED congestion avoidance mechanism work with colors, colored by policing in the ingress stage.

Also, per-port shaping is supported co-work each queue as hierarchical shaping
