3.2.4 Static Routing Table Example

3.2.4.1 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 both Intranet and Internet resource through

E1/T1 connections.

Figure 3-5 ET100R Static Routing Example

3.2.4.2 Preparation

This is a more complex application where LAN B now has 2 routers, one for Internet access and one for LAN-to-LAN

access over E1/T1.

• E1 or T1 connectivity establishment.

• IP addressing scheme and planning.(Table 3-4)

Table 3-4 Addressing scheme and planning.

• Routing protocol: Static route

• Encapsulation: PPP.

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

• Deployment: CLI commands.

3.2.4.3 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).
