Ethernet User Port

IPmux-1/1EInstallation and Operation Manual	Chapter 1 Introduction

The Ethernet user port allows a user to aggregate both TDMoIP traffic and his private network LAN traffic to a single Ethernet network connection without requiring an access switch. This is a cost effective solution for MTU or small office applications. A rate limiter to restrict user port traffic is supported.

IPmux-1/1E contains an internal switch where one of its ports is connected to a TDMoIP interworking function, another internal switch port is used as the user port, and the third is used as an Ethernet network port.

Note Priority is always given to TDMoIP packets inside the internal switch.

Internal Switch Operation Modes

Bridge Mode (no user rate limiter)

In this mode the internal switch performs transparent bridging, ALL internal ports learn, update the internal tables, and make forwarding decisions according to the source MAC only (not MAC + VLAN ID).

VLAN tagged frames are supported, however forwarding decisions are based on MAC only.

Rate Limiter Mode

In this mode a rate limiter is available to limit user port traffic. This feature is valuable when a limited bandwidth DSL modem, for example, is used to extend the Ethernet link (generally when the Ethernet link rate is limited/shaped to a lower rate after IPmux). In this case TDMoIP packets will be dropped in the modem even if it was prioritized at the IPmux internal switch. This is prevented by limiting the user port to actual link rate minus TDMoIP bandwidth. The rate limiter can limit user traffic at 50 kbps steps up to 5M and in 1 Mbps steps from 5M to 100M.

The internal switch (in the rate limiter mode) operates in the following way:

•The network port is in lock mode (no learning takes place). If this port must be connected to a switch (not a hub), this is not a limitation, since all applications involve connection to a backbone on an access switch.

•VLAN tagged frames are not supported (will be dropped)

•Access to the IPmux host for management is possible only from the network port.
