3.2.3 PPP Encapsulation

3.2.3.1 Scenario

This is a typical application using CTC Union's ET100R with E1/T1 series access units or multiplexers. The

ET100R router module with PPP WAN encapsulation enables you to access the Intranet or Internet resource through the

E1/T1 connection.

3.2.3.2 Preparation

Although this is a simple point-to-point application, you must deal with it very carefully. There are some reference

points to consider regarding this application.

• E1 or T1 connectivity establishment.

• IP addressing scheme and planning.(Table 3-3)

Table 3-3 Addressing scheme and planning

• Routing protocol: Static route

• Encapsulation: PPP.

• Administration: System name, System information, Configuration check, Interface summary.

• Deployment: CLI commands.

3.2.3.3 Deployment procedures

1. E1 or T1 connectivity establishment.

Please refer to CTC Union's E1/T1 DSU/CSU product manual for further operation.

2. IP addressing setting: Configure static IP addresses in PCs on LAN A (local) and LAN B (remote).
