Example for Configuring WAN Interconnection Using E1/T1 Interfaces

Example for Configuring WAN Interconnection Using E1/T1 Interfaces

Specifications

Only the 1E1T1-F/2E1T1-F/4E1T1-F/8E1T1-F interface card supports E1-F interfaces.

Only the 1E1T1-F/2E1T1-F interface card supports T1-F interfaces.

Networking Requirements

As shown in Figure 3-1, an enterprise's headquarters and branch are connected through a carrier's transmission network. The enterprise requires a low-rate (for example, 512 kbit/s) E1 channel to transmit services. In this scenario, timeslots in the E1 line need to be bundled into a channel. For example, eight timeslots are bundled to transmit data services.

Procedure

  1. Configure the 1E1T1-F/2E1T1-F interface card to work in E1-F mode.

    NOTE:

    By default, a 1E1T1-F/2E1T1-F interface card works in E1-F mode.

    A 4E1T1-F/8E1T1-F interface card works only in E1-F mode and does not support mode switching.

    1. Choose WAN Access > E1/T1 Interface > Mode Switching. The Mode Switching page is displayed.

    2. In the E1/T1 Card List area, select an E1/T1 card whose mode needs to be switched, and click next to the card in the Operation column.

    3. Click OK.

      The configuration takes effect after several minutes.

  2. Modify the configuration of an E1 interface.

    1. Choose WAN Access > E1/T1 Interface > E1 Interface. The E1 Interface page is displayed.

    2. In the E1 Interface List area, select an E1 interface to be configured, and click next to the interface in the Operation column. The Modify E1 Interface dialog box is displayed.

    3. Click OK.

  3. Configure the physical attributes and link layer attributes of an E1 interface.

    1. Choose WAN Access > E1/T1 Interface > E1 Interface to display the E1 Interface page.

    2. In the Attribute column of the E1 Interface List area, click Configuration. The Configure E1 Interface Attributes dialog box is displayed.

      NOTE:

      When an E1 interface functions as a Data Circuit-terminating Equipment (DCE) interface, it must work in master clock mode and provide clock signals for a Data Terminal Equipment (DTE) interface. When an E1 interface functions as a DTE interface, it must work in slave clock mode and obtain clock signals from a DCE interface.

    3. Click OK.

  4. Enable an E1 interface.

    1. Choose WAN Access > E1/T1 Interface > E1 Interface to display the E1 Interface page.

    2. In the E1 Interface List area, select an E1 interface to be configured, and click next to the interface in the Operation column.

    3. Click OK.

  5. Check whether the configured E1 interface is on the E1 Interface page.

Configuration Notes

Two connected E1 interfaces must be configured with the same parameters except for the clock mode; otherwise, devices on both ends cannot communicate properly.
