3 • Planning the installation
Network information
Network connection considerations that you should take into account for planning are provided for several
types of network interfaces. They are described in the following sections.
Network diagram
Draw a network overview diagram that displays all neighboring IP nodes, serial connected elements and ISDN
components. It is recommended that you keep a copy in the site log (see
“Site Log”
on page 62 for more infor-
mation on keeping a site log).
IP related information
Before you can set up the basic IP connectivity for your SmartNode 1000 or 2000 series you need to have the
following information:
•
IP addresses used for Ethernet LAN and WAN ports
•
Subnet mask used for Ethernet LAN and WAN ports
•
Lengths of Ethernet cables
•
IP addresses of central H.323 gatekeeper
•
IP addresses of central PSTN gateway for H.323 and/or ISoIP-based calls
•
IP addresses of central TFTP server used for configuration upload and download
ISDN related information
To set up basic ISDN connectivity for your SmartNode 1000 or 2000 series you need to do or know the following:
•
Check whether an additional line power is necessary and if an optional Phantom power supply or line
power module needs to be installed
•
Clock source for ISDN E1 interface
•
Length of the ISDN S-Bus or E1 interface cables
•
The block of sequential numbers assigned by your telecom operator that are used for the direct dial inwards
(DDI) numbering plan to be used together with your PBX
•
Define a multiple subscriber numbering (MSN) schema to give your individual endpoint a unique phone
number that can be dialed directly
•
Check whether an ISDN port is to be configured in USR (TE) or NET (NT) mode
•
Check whether an ISDN port is to be configured as point-to-point or point-to-multipoint link
S-Bus installation
When installing an ISDN S-bus and up to eight connected devices, bear in mind that the relevant ITU-T,
ETSI and ANSI standards for your equipment must be met. Your ISDN provider will help you to ensure that
you comply with the relevant standards.
An S-Bus must be terminated at both ends with 100 ohm; such termination should be at the extreme ends of
the bus.
