Total Access 544R System Manual Section 5 DLP-14

1. Verify the unit is at factory default.

2. Connect the network interface cable to the NTWK port on the rear of the unit.

3. Power up the unit.

4. The unit begins auto-detecting whether the packets received on the WAN interface are PPP LCP

packets or Frame Relay signaling packets. When the second consecutive control packet of the same

type is received, the unit configures itself for the detected L2 protocol. When the next control packet of

the same type is received, the L2 protocol is confirmed, and the auto-detection of the L2 protocol is

complete.

If PPP is detected:

• The unit's PPP interface is set to accept its IP address from the service provider's peer router via the

PPP IPCP config-NAK mechanism as described in RFC 1332.

• The unit automatically sets its default route to the service provider's edge router address as

identified by PPP IPCP.

If Frame Relay is detected:

• The frame relay network signaling is further analyzed to automatically detect the signaling protocol

being used (Annex D, Annex A, or LMI).

• Next, the unit automatically adds the first indicated Frame Relay PVC as an interface to the IAD

router.

• When the PVC becomes active, the unit broadcasts a DHCP request toward the provider edge router

over the active PVC.

• When a DHCP response is received, the unit assigns the address indicated by the DHCP server as

its WAN IP address. The address indicated as the gateway address is set as the default gateway.

Additional information provided may also be used such as DNS server addresses, WINS addresses,

Domain name, Host name, etc.

5. Once the L2 protocol detection is complete, the service provider can Telnet into the unit using the IP

address assigned by the router/DHCP server.

6. Load the desired configuration file. The config file may be one of the following two formats:

• A .cfg file which is loaded via TFTP. See DLP-9, Saving the Current Configuration Using TFTP.

• A script obtained via the terminal mode. (See DLP-13, Saving and Loading Text Configuration

Using the Terminal Command Line, section only).

7. Set the failsafe timer by selecting SYSTEM UTILITY >TERMINAL MODE and typing fstimer start x, (where

x is in seconds) at the > prompt. Select a value for x which will allow enough time for the service

provider to reconfigure the network to match the unit's new configuration and which will allow an extra

3 to 5 minutes for the unit to sync up with the network.

Perform Steps Below in the Order Listed

The service provider's access network Layer 1 must be provisioned to map a single 64K

DS0 from the provider's network to DS0 24 on the customer's T1 circuit with matching

circuit parameters (ESF, B8ZS).
