Ip-Dect System Management - Avaya DECT R4 Installation And Administration Manual

Sync radius: The radius of the circle, around a particular IPBS, in which other IPBSs lose
synchronization with that IPBS with a given synchronization loss probability. The size of the
sync radius depends on requested probability of losing synchronization. See
speech sync radius.
Note:
A value of -80 dBm is a recommendation to ensure good sync conditions.
Note:
Ring synchronization
Each synchronization port sends and receives synchronization signals. Each IPBL has two
ports in and out for ring synchronization and two ports in and out for reference synchronization.
The ring synchronization can be made in two different ways:
Redundant (preferred)
●
Non-redundant
●
Each synchronization ring dynamically assigns a sync master.

IP-DECT System Management

Onsite management
To manage IPBS and IPBL, use the web GUI that can be accessed over the LAN.
Remote management
The IPBS and IPBL have support for remote setup and configuration over the Internet.
IP administration security
All IP administration is based on secure IP. IPBS and IPBLs are password protected in order to
prevent unauthorized access.
IPBS,IPBL, AIWS, and AIWS2 offer a set of default passwords for several user accounts in a
factory fresh installation. During installation, you must change the default password for all
existing accounts according to the described installation process for each particular device.
