Hi,

Device Interconnection

Interconnecting with a Non-Huawei Device

An AR router can interconnect with a non-Huawei device without traversing a transmission network in the following cases:

Case 1: back-to-back interconnection, with no E1 protocol converter

As shown in Figure 1-6, an AR router interconnects with a non-Huawei device through an E1 leased line in back-to-back mode with no E1 protocol converter between them.

Typical cases of the back-to-back mode are as follows:

  • AR [DB9 --- RJ45] <--------------> [RJ45] non-Huawei device
  • AR [RJ45 --- BNC] <--------------> [BNC] non-Huawei device

Case 2: interconnection through an E1 protocol converter

As shown in Figure 1-7, the E1 leased line of an AR router interconnects with the SA link of a non-Huawei device through an E1 protocol converter. This mode is seldom used on live networks, and is not discussed here.

You can purchase the E1 protocol converter from a third-party vendor. The E1 protocol converter and the E1 interface must work in unchannelized mode.

Interconnecting with an SDH/PDH Optical Transmission Device

Typically, an AR router interconnects with a non-Huawei device through a transmission network. An AR router can interconnect with an SDH/PDH optical transmission device in the following modes:
