SmartNode 4950-NCE User Manual 1 • General information
SN4951-NCE model codes
The high precision SmartNode 4951-NCE models have a Stratum III clock. The Stratum III clock provides a
clock source of < 5 ppm. For PBXs that used to rely on PSTN for accurate clock source, the SmartNode 4951
can provide a PSTN-equivalent high precision clock. The popular DECT PBX needs such high precision
clocks.
Note For high precision clock models, replace SN4950-NCE with SN4951
in the model code.
