1 • General information
SN4990 Series model codes
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
Table 4
,
Table 5
,
Table 6
and
Table 7
.
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
.
