SmartNode 4980 and 4990 Series overview

SmartNode 4980 & 4990 User Manual 

The SmartNode 4990 series consists of several models. They differ in the number of PRI ports and voice chan-
nels supported. All SN4991 models come equipped with two 10/100/1000Base-T Ethernet ports and a high 
precision clock. The SmartNode 4991 models are listed in 

 and table 5.

For SN4991 models, the Stratum III high precision clock provides a clock source of < 5 ppm. For PBXs that 
used to rely on PSTN for accurate clock source, the SmartNode 4991 can provide a PSTN-equivalent high 
precision clock. The popular DECT PBX needs such high precision clocks
