Physical connections:
Verify that an ESB2 card is installed in the Abilis. If the card isn't present, insert it in a free PCI slot.
Connect the ESB2 synchronous port to the DCE modem using the “octopus” cable connector numbered with “0”.
Before proceeding with the configuration, make sure you have the following parameters available from your ISP.
| Parameter | Possible values |
|---|---|
| AR (Access Rate) | 2048000 bit/sec |
| CIR (Committed Information Rate) | 1024000 bit/sec |
| MCR (Minimum Cell Rate) | 1024000 bit/sec |
| PCR (Peak Cell Rate) | 1600000 bit/sec |
| CIR (Committed Information Rate) | 1024000 bit/sec |
| TC (Committed rate measurement interval) | 0.010 sec |
| LMI (Local Management Interface) standard | cisco |
| DLCI (Data-Link Connection Identifier) | 20 |
| IP address and Mask | 81.81.81.81/32 |
Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.
| a dev:esb-1 | Add an ESB device (e.g. ESB-1). |
| a res:fr-1 subtype:dl | Add a “Frame Relay over Dedicated Line” resource (e.g. FR-1). |
| s p fr-1 lowres:sync-1 | Configure SYNC-1 resource as the lower FR-1 resource. |
| s p sync-1 clk:ext sp:2048000 | Configure the clock source type and the Access Rate for the SYNC-1 resource. |
| a res:ip-4 subtype:dl | Add an “IP over Dedicated Line” resource (e.g. IP-4). |
| s p ip-4 lowres:fr-1 | Configure the FR-1 as the lower resource of IP-4. |
| s p fr-1 lmi:yes std:cisco ar:2048000 | Configure the LMI standard and the Access Rate. |
| s p ip-4 enc:fr-ietf | Configure the encapsulation type. |
| s p ip-4 cir:1024000 bc:10240 be:5760 | Configure the CIR, BE and BC vaule. |
| s p ip-4 ipadd:81.81.81.81 mask:255.255.255.255 | Configure the IP address and the mask. |
| s p sync-1 descr:HDSL_1 | Configure the description of the SYNC resource. |
| s p fr-1 descr:HDSL_1 | Configure the description of the FR resource. |
| s p ip-4 descr:HDSL_1 | Configure the description of the IP resource. |
| save conf | Save the configuration. |
On a working Abilis, a system restart is required to make the ESB-1 device, the FR-1 and IP-4 resources running.
