SmartNode 4980 & 4990 User Manual 1 • General information
SN4980 Series model codes
The SmartNode 4980 series consists of several models. They differ in the number of PRI ports and voice chan-
nels supported. All models come equipped with two 10/100/1000Base-T Ethernet ports. The SmartNode
4980 PRI ports and voice channels are listed in table 2, and high precision clock models are listed in table 3.
The high precision SmartNode 4981 models have a Stratum III clock that provides a clock source of < 5 ppm.
The SN4981 can provide a PSTN-equivalent clock for PBXs that used to rely on PSTN for an accurate clock
source. The popular DECT PBX needs such high precision clocks
.
