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-NCEwith SN4951 in the model code.
