Multi-Tech Systems MVPFXS-8, MVPFXS-24 IP Parameter Definitions, Field Name Values Description

Technical Configuration MultiVOIP FXS User Guide

The IP Parameters fields are described in the tables and text passages below. Note that both DiffServ parameters (Call Control PHB and VoIP Media PHB) must be set to zero if you enable Packet Prioritization (802.1p). Nonzero DiffServ values negate the prioritization scheme.

		IP Parameter Definitions
Field Name	Values	Description
Ethernet Parameters
Frame Type	Type II, SNAP	Must be set to match network’s frame type. Default is Type II.
DiffServ	DiffServ PHB (Per Hop Behavior) values pertain to a differential prioritizing
Parameter	system for IP packets as handled by DiffServ-compatible routers. There are 64
fields	values, each with an elaborate technical description. These descriptions are found in
	TCP/IP standards RFC2474, RFC2597, and, for present purposes, in RFC3246, which
	describes the value 34 (34 decimal; 22 hex) for Assured Forwarding behavior (default
	for Call Control PHB) and the value 46 (46 decimal; 2E hexadecimal) for Expedited
	Forwarding behavior (default for Voip Media PHB). Before using values other than
	these default values of 34 and 46, consult these standards documents and/or a
	qualified IP telecommunications engineer.
	To disable DiffServ, configure both fields to 0 decimal.
	The passage following this table explains DiffServ in the context of the IP datagram.
Call Control	0 – 63	Value is used to prioritize call setup IP packets.
PHB	default = 34
	.
Voip Media	0 – 63	Value is used to prioritize the RTP/RTCP audio IP packets.
PHB	default = 46

IP Parameter fields
Gateway	alphanumeric	Descriptor of current voip unit to distinguish it from other units in
Name		system.
Enable DHCP	Y/N	Dynamic Host Configuration Protocol is a method for assigning IP
	disabled by	address and other IP parameters to computers on the IP network in a
	default	single message with great flexibility. IP addresses can be static or
		temporary depending on the needs of the computer.
IP Address	4-places, 0-255	The unique LAN IP address assigned to the MultiVOIP.
IP Mask	4-places, 0-255	Subnetwork address that allows for sharing of IP addresses
		within a LAN.
Gateway	4-places, 0-255.	The IP address of the device that connects your MultiVOIP to the
		Internet.
