iPECS UCP - System Ip Address Plan

iPECS eMG80 & eMG800 & UCP
Administration and Programming Manual Issue 1.6
251
The System IP Plan sets several IP addresses including MPB (UCP) IP address that is required
for external VoIP calls, the IP address for the router, and the system‘s internal private IP address
Plan. Note that the LAN and Router addresses must be routable IP addresses for access to an
external VoIP network, remote access by an iPECS Phone or remote Web access. When used,
the LAN port of the VVMU(eMG80), VOIB(eMG800) or VOIM (Voice over IP device unit) must
also have a routable IP address for access to/from an external VoIP network and a remote iPECS
device.
When “Automatic IP Assign” is enabled, the system will assign IP addresses to each iPECS IP
terminal and gateway Modules including any VOIM using the System IP address range defined.
These addresses are used for communications between the system and other VOIMs and
terminals.
When “Automatic IP Assign” is enabled, the system will assign IP addresses to each iPECS IP
terminal and Board (Gateway Modules) including any VVMU, VOIB or VOIM using the System IP
address range defined. These addresses are used for communications between the system and
other VVMU (VOIB, VOIM) and terminals.
The system may be connected to a LAN that is segmented by two separate private IP address
schemes. This segmenting technique is often used to separate voice and data devices. However,
with this segmenting technique, the system will normally treat the segmented devices such as IP
soft phones, as remote devices, using valuable WAN bandwidth. Assigning the “Second Sys IP
address” with a valid IP address from the second segment permits the system to communicate
directly with the devices over the LAN.
iPECS can be installed behind a NAPT server, if the NAPT server provides fixed address
translation and port forwarding to the system. In this case, the system will employ the “Firewall IP
address” as the fixed IP address for communication with remote devices. This address must be
assigned as the “MPB (UCP)” address in the remote device.

remote user and external VoIP network access. IPv4 format.
10.10.10.2
MPB (UCP) Subnet Mask Defines the system subnet for MPB (UCP) IP addresses. 255.255.255.0
Router IP Address
IP Address of router for external network (WAN) access. Required
for shared voice and data LAN, external VoIP and remote Web
access.

System Subnet Mask Define the system subnet for private IP addresses. 255.255.255.0
Automatic IP Assign
The system automatically assigns IP addresses to modules and
terminals (ON) or, when OFF, IP addresses are assigned
manually in Device IP Address Table or from the DHCP address
assigned to the device.
ON
Second System IP
Address
When devices have different address schemes on the same LAN,
enter an IP address from the second LAN for use by the system.
