Page 14: Important Parameters
Synchronization and Deployment Guide Important parameters When deploying there are 3 parameters which are equally important: • RSSI-values: Value indicating signal strength • Q-value: Value indicating the signal quality (preferably steady at min 64) • Sound Quality: Measured by walking away from the base station with the handset and measure where the RSSI value drops below 75 and the Q-value stays constant at 64. -

Necessary overlap in sync chains Necessary overlap between sync chains Deployment procedure Start by placing your tripod with the Spectralink IP-DECT server 400 (from your deployment tools) where you plan the first base station (the sync master) to be: 14169000 Version 9.3... - Page 16 Consider where to place the next base so that the handset gets opportunity to handover to the next base. Determine where to place the next bases. • Move your tripod with the Spectralink IP-DECT server 400 to the next placement. • Take picture of the placement and note it on a blueprint of the building.

Page 24: Lan Based Radio Synchronization
Below you will find a description of how LAN based radio synchronization works, and what must be considered when synchronizing. The latest generation of Spectralink IP base stations support the use of corporate Local Area Network (LAN) for synchronization of the DECT radios when running software release PCS15C or later. -
Page 25: Deployment Of Base Stations
Synchronization and Deployment Guide Deployment of Base Stations When the base station radios are synchronized via radio, the base stations that synchronize to each other must be within radio coverage of each other. This is not required when LAN based radio synchronization is used. -
Page 26: Multicast
Any single switch in the network cannot exceed 100nsec of jitter. PTPv2 event traffic must be given strict priority over all other network traffic. Multicast and the IGMP protocol (if used) must be configured per Spectralink requirements. Several factors influence the packet delay: 14169000 Version 9.3... -
Page 27: Network Topology
Synchronization and Deployment Guide • Network topology • The traffic patterns on the network • The quality and configuration of the switches Network topology Every time a PTPv2 packet passes through a switch - jitter is potentially added. Therefore, the number of switches between all base stations must be kept low. -
Page 28: Quality And Configuration Of The Switches
Synchronization and Deployment Guide If the traffic load causes problems for the base station synchronization, it may be necessary to separate the base stations from the data network. Be aware that separation via VLAN may not help as it is still using the same physical link. Quality and Configuration of the Switches The LAN based synchronization is highly dependent on the quality and configuration of the deployment network. - Page 29 Synchronization and Deployment Guide Default sync type This setting controls the default synchronization type for new base stations. The following values can be selected: • Free running • Radio (default) • LAN sync transport protocol This setting controls the protocol used as transport for the PTPv2 packets used for synchronization.
- Page 30 Synchronization and Deployment Guide The “Lost” column displays the number of times the synchronization has been lost and a percentage which is the ratio of time the base station has been without synchronization. The lost counter must be low but is expected to grow slowly over time. The percentage will start high and must be zero after some time.
