For information about installing a PIC see the Port Interface Card Quick Install
Guide.
For detailed information about PIC hardware see the Port Interface Card
Hardware Reference.
Connecting to a Leased Line Circuit
Leased lines are a commonly used for building Wide Area Networks (WANs).
A leased line maybe the right solution if you need to connect distant sites
across public areas. By installing an AT-AR023 SYN PIC in your router this
option is available to you.
To connect your router with an AT-AR023 SYN PIC installed to a
synchronous leased line circuit, follow these steps
The following steps are required:
1. Follow the instructions in the Port Interface Card Quick Install Guide on how
to install the AT-AR023 SYN PIC.
2. Use the appropriate approved transition cable (RS-232, X.21 or V.35), to
connect the synchronous port on the rear panel of the AT-AR023 SYN PIC
to the telecommunication service provider’s NTU.
3. To check the configuration of the port, enter the command:
show syn=n
where n is the synchronous port number. Verify that the information
displayed is correct. In particular, you should set “State” to “enabled” and
“Interface type” should match the transition cable used.
4. Configure a data link layer module, such as PPP (Point-to-Point Protocol),
Frame Relay or X.25 LAPB, to use the synchronous interface. To create a PPP
interface 0 to use synchronous port 0, enter the command:
create ppp=0 over=syn0
5. To check the configuration, enter the commands:
show syn=0
show ppp=0
The output of the SHOW SYN command should show “Active” set to “yes”
and “Module” set to “ppp”. The output of the SHOW PPP command should
show interface ppp0 over syn0 with “LCP” as the control protocol. The Tx
and Rx LEDs are lit as data is sent and received on the interface.
6. Check IPX circuit configuration
To check that the IPX circuits are correctly configured on each router repeat
steps 1 through 3 above, or enter the command:
show ipx circuit
Check that there are two circuits, and for each circuit check that the circuit
is enabled, uses the correct interface and encapsulation (for Ethernet
interfaces), the network number is correct and “On demand” is set to “no”.
If not, then repeat steps 1 through 3.
7. Contact your authorised distributor or reseller for assistance
If you still have no visible routes to the remote router, contact your
authorised distributor or reseller for assistance.
