Ip Network Configuration - Nortel CS 1000 User Manual

the DECT manager WEB interface. Automatically assigned RPNs start at
010. If you manually assign a new RPN, ensure that it is in the range 000 .
. . 00F.
ATTENTION
It is very important that you determine the position of the Synchronization Master
before you start site planning. Place the synchronization master, which is the
DAP with the lowest RPN, in the middle of your site, building, or buildings.
IP network configuration
The IP network must be capable of supporting SIP DECT; this section
provides more information about planning an IP network that is suitable for
supporting SIP DECT.
SIP DECT system typically uses existing IP network infrastructure and
facilities for the network connection. For IP connectivity, the network must
be configured in such a way that all SIP DECT components have the
following characteristics.

are equipped with unique IP addresses (some static, some dynamic)
can reach all the required services
can be reached by all their clients and counterparts
The Quality-of-Service that is offered by the IP network must be
sufficient for the Voice-over-IP application SIP DECT.
The IP network must support transparent IP multicast between all
DAPs and the DAP controller.
Connect only one DAP to one IP Switch port.
DAP supports full duplex and supports autonegotiation if DAP is
connected to a port on an Ethernet Switch.
ATTENTION
Autonegotiation must be used on the Ethernet switch ports connected
to DAPs. Full duplex can be tried only if the switch does not support
autonegotiation. In that case, the correct operation of SIP DECT is not
guaranteed and the results can vary for different Ethernet switches.
Enough unique IP addresses must be available to support both data
networking traffic and SIP DECT components. Private IP addresses
can be used for local traffic, and private IP addresses on the local
network can also be used to connect to public IP addresses if Network
Address Translation (NAT) is used. However, NAT is not supported
by SIP DECT.
