Data network prerequisites checklist

Before you set up voice over IP (VoIP) trunks or IP telephones on a BCM, complete the following
checklists to ensure the system is correctly set up for IP telephony. Some items in the checklist do
not apply to all installations.

Network diagram

To aid in installation, a network diagram provides a basic understanding of how the network is
configured. Before you configure IP functionality, create a network diagram that captures all of the
information described in
do not need to answer the last two questions.
Table 97 Network diagram prerequisites
Prerequisites
1.a Are you using the BCM50a or BCM50e, and has a network diagram been developed? (If you
are not using the BCM50a or BCM50e, it is assumed that the BCM is being installed on an
existing network).
1.b Does the network diagram contain any routers, switches or bridges with corresponding
IP addresses and bandwidth values for WAN or LAN links?
1.c Does the network diagram contain IP Addresses, netmasks, and network locations for all BCM
systems and other BCM products?
1.d Answer this if your system will use IP trunks; otherwise, leave it blank: Does the network diagram
contain IP addresses and netmasks of any other VoIP gateways to which you must connect?
1.e Answer this only if your system will use a gatekeeper; otherwise, leave it blank: Does the network
diagram contain the IP address for any Gatekeeper that may be used?
