SmartNode 4970 User Manual 1 • General information
SN4970 model codes
The SmartNode 4970 series consists of several models. They differ in the number of PRI ports and voice chan-
nels supported. All models come equipped with one 10/100/1000Base-T Ethernet port. The SmartNode 4970
PRI ports and voice channels are listed in table 2.
SN4971 model codes
The high precision SmartNode 4971 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 4971 can
provide a PSTN-equivalent high precision clock. The popular DECT PBX needs such high precision clocks.
Note For high precision clock models, replace SN4970 with SN4971 in
the model code.
