Protocol

• HDLC
• Cisco HDLC
• PPP
• ANSI (Frame Relay)
• CCITT (Frame Relay)
1. Select the desired T1 protocol.
2. Press Submit.
Frame Relay Mode and DLCI
When the Protocol is one of ANSI or CCITT, then additional Frame Relay
configuration parameters are required.
The Frame Relay Mode is usually set to DTE for the customer premises.
The Frame Relay DLCI is set by the WAN provider and identifies the far-end
device across the Frame Relay network. This DLCI can also be used to carry
voice traffic only by enabling the Secondary DLCI for data.
Most installations will use a single DLCI for both voice and data traffic.
However, in instances where the network will provide a different quality of
service based on DLCI number it is desirable to place all voice traffic on one
DLCI and then configure a second DLCI for data. In this case, the Secondary
DLCI is configured as follows:
1. Select Network.
2. Select the T1 link next to the radio button to proceed to the T1
configuration page.
3. Select Enable in the Frame Relay Secondary Settings section of the page.
4. Enter the Secondary DLCI, IP Address, Network Mask and Gateway for
the data traffic using the Secondary DLCI.
