ATM and Packet over SONET/SDH at 155 Mbps
When analyzing ATM
real-time (full rate) AAL-2 and AAL-5 reassembly is performed simultaneously on more
than 5120 virtual channels and the resulting frames are passed from the LIM to the
acquisition system for further analysis. Cell mode is also available. ATM Policing can be
performed on up to 1024 virtual circuits in frame mode or cell mode simultaneously with
other measurements.
The LIM has optical interfaces and can be used in single-mode or multi-mode
environments; when used in multi-mode environments, 10 dB attenuators should be used
on the optical outputs. Both SDH and SONET framing are fully supported in this LIM.
Common to Inputs and Outputs:
Framing:
- SDH: STM-1, ITU-T G.707
- SONET: STS-3c, GR-253
SDH / SONET Frame Scrambling (x7 + x6 + 1)

(default) or off
Inputs:
Two input and output ports (single-mode/multi-mode compatible)
