SmartNode 4960 Getting Started Guide

SN4961 models

The high precision SmartNode 4961 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 4961 can
provide a PSTN-equivalent high precision clock. The popular DECT PBX needs such high precision clocks.

SN4960 failover relay models

The SmartNode 4960 Series Failover Relay models provide the high level of reliability required for Enterprise
installations. This feature ensures that in the event of a SN4960 power failure, you can still make calls through
the PSTN. The diagram below shows how this feature works:
In this typical installation example, the SN4960 PRI lines will be connected to the PSTN via T1/E1 port 0/0,
and will connect to the office PBX through one or more of the remaining ports. If the SN4960 experiences a
power failure, the Failover Relay between ports 0/0 and 0/1 will close and the SN4960 will still be able to con-
nect PBX port 1 to the PSTN. This allows mission critical voice calls to be relayed to the PBX.
