Frame Relay Interfaces and Ports
This section shows the minimum configuration required to configure a frame relay interface on a channelized line card.
To create and configure the frame relay interfaces and ports:
To create and configure the frame relay interfaces and ports:
Step 1
Select a channelized line card (CLC/CLC2) and set the framing method by applying the example configuration in
Step 2
Configure the path, framing, mapping, Frame Relay characteristics, and the data link connection identifiers (DLCIs) as
illustrated in the example configuration in
illustrated in the example configuration in
Step 3
Configure the appropriate timing source (BITS from the SPIO or line-timing from attached remote) to ensure transmit
synchronization by applying the example configuration in the Configuring Transmit Timing Source section in System
Settings.
synchronization by applying the example configuration in the Configuring Transmit Timing Source section in System
Settings.
Important:
Before you can move to Step 4 to bind a DLCI to a port, you must complete the link configuration
by configuring Peer-NSEIs and/or SS7 routing domains as described in SGSN Service Configuration Procedures in
the SGSN Administration Guide. Return to this procedure when your link configuration is complete.
the SGSN Administration Guide. Return to this procedure when your link configuration is complete.
Step 4
Step 5
Verify the card, port and link configuration and status with the commands illustrated in the verification examples below.
Step 6
Save the configuration as described in the Verifying and Saving Your Configuration chapter.
Setting the Characteristics of the Channelized Line Card
Use the following example to set the operational characteristics, the framing type, the header type, the service type, and
the boot time E1 framing type, for the Frame Relay Channelized Line Card (CLC):
the boot time E1 framing type, for the Frame Relay Channelized Line Card (CLC):

card slot
framing framing_type [ ds1 | e1 ]
header-type { 2-byte | 4-byte }
initial-e1-framing { crc4 | standard }
service-type frame-relay
no shutdown
end
Notes:
Make a note of the information you configure - you will need it again later for the path command used to
configure channel characteristics.
