IP Series Installation Manual
Note that only the first 195 ports within that range are actually used. The gateway router will need
to be programmed to open UDP ports xx001–xx195, inclusive, where xx represents the two-digit
number that designates the UDP port range.
Example: The System Administrator for IP PBX 705 in Chicago realizes that he is already using
UDP port 59123, which falls in the default range, so he decides instead to use
56000 as the base UDP port. He will use F82 to assign that range by pressing 5 6
#. The IP PBX will automatically be assigned a UDP port of 56001. Extension 100
will automatically be assigned a UDP port 56100, x121 will have a UDP port of
56121, and so on. (In a multisite environment, the administrator in Chicago must
ensure that all other administrators in the company know that he is using 56000
as his base UDP port, so that they can program their IP PBXs accordingly.)
Function 822: Assign IP address pool for local IP phones
Note: If you are supporting both IP Series and IP-compatible IVX products, be aware that this
feature is used only by the IP 200 and IP 40, not by IVX products. On an IVX product, press #
until you're back to the F82 display.
The administrator determines the IP address range to be used by the phones. The EHCP program
will assign the IP phone's IP address from this pool. The IP addresses should, for ease of use, come
from the same subnetwork as the IP PBX. For example, if the IP PBX is using 192.168.210.1, the IP
phones should use a block of 96 addresses from within that subnet. The default starting IP address
is 192.168.248.2.
The administrator will enter only the first IP address to be used, followed by the # key. Each exten-
sion that comes on line will be assigned the next available address. Specific IP addresses from
within the subnet can be assigned using Function 82. Press the # key to enter the dot between the
octets. Press # again when finished.

Function 823: Remote channels
This function sets the number of remote channels available for use by Remote IP Feature Phones.
This is allowed so that such phones don't use up all network bandwidth. A conversation over a
Remote IP Feature Phone uses approximately 44K of bandwidth; so, depending on the amount of
available bandwidth on the network, you may want to restrict the amount of bandwidth used by
Remote IP Feature Phones and Esi-Link.
Example:
If total available network bandwidth between sites is 256K and five remote chan-
nels are in use simultaneously (thus consuming approximately 86% of the 256K),
the network will become congested, having an adverse impact on other data
transmissions (e.g., file movement, printing, etc.) on the site-to-site network.
You must have a Remote Network Card (RNC) installed to set this parameter. If you have an RNC 3
card installed, you can set one, two or three remote channels; if you have an RNC 12 card installed,
you can set one to 12 remote channels.
Enter the number of remote channels and press # to confirm.
