Introduction
The T-DAC offers in-band management over Frame Relay or PPP (point-to-point protocol) links in the T1/E1
channels. The T-DAC’s Frame Relay subsystem manages the in-band management function over Frame Relay
links. This chapter discusses in-band management using Frame Relay (for PPP, see chapter 14, “PPP” on
page 215).
Configuring a Frame Relay link
The most common configuration is setting up the T-DAC as a DCE and connecting to a provider’s Frame
switch via a T1/E1 line. In this application, the T-DAC will establish a point-to-point link via one or more
DLCI’s or virtual channels. Each DLCI is a pipe with an associated far-end IP address.
A Frame Relay link is configured as follows:
• Selecting a T1/E1 DS0 for management using Frame Relay
• Selecting the correct Frame Relay configuration parameters (LMI)
• Assigning an IP address to the DLCI
• Assigning next-hop routes to the new DLCI
T1/E1 port and DS0 selection
The first stage in setting up a Frame Relay WAN link is configuring one or more DS0s on any T1 or E1 line for
Frame Relay in-band management. See chapter 20, “T1/E1 Link” on page 285 for T1/E1 port configuration.
1. Click on the T1/E1 Link under the configuration menu to display the T1/E1 Link Activity main window.
Select which T1/E1 port will carry the Frame Relay Link, then click on the View Link of the selected port.
2. Click on Channel Assignment link to access the WAN Circuit Channel Assignment window. Options for
the T1/E1 DS0s displayed on this window are:
– clear(9). The T1/E1 DS0s carry user data (default)
– framerelay(3). The selected DS0s will carry management data using Frame Relay
– ppp(5). The selected DS0s will carry management data using PPP
3. Use the drop down menu to select Frame Relay for the designated management channel(s). Set user data
DS0s to Clear.
4. Click on the Submit Query button for the configuration to take effect.
The Management DS0 IS now active on your T-DAC. The next stage is to configure Frame Relay and IP routing.
