Appendix H - Connection Setup
Creating a WAN connection is a two-stage process.
1 - Setup the Layer 2 Interface (ATM or Ethernet)
2 - Add a WAN connection to the Layer 2 Interface.
The following sections describe each stage in turn.
H1 ~ Layer 2 Interfaces
The CT-5364A supports WAN connections over ATM or Ethernet interfaces, but these
two interface types cannot be used in tandem, i.e. you must choose one.
Before proceeding to either the Ethernet instructions in section H1.2 or the ATM
instructions in section H1.3, please read about connection modes in section H1.1.
H1.1 Connection Modes
Every layer2 interface operates in one of three modes: Default, VLAN Mux or MSC.
A short introduction to each of these three modes is included below for reference.
It is important to understand the differences between these connection modes, as
they determine the number and types of connections that may be configured.
DEFAULT MODE
In this mode there is a 1:1 relationship between interfaces and WAN connections, in
that an interface in default mode supports just one connection. However, unlike the
multiple connection modes described below, it supports all five connection types.
The figure below shows the full range of connection types available in default mode.
