Hi,
Device InterconnectionInterconnecting with a Non-Huawei DeviceAn 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. Figure 1-6 Connecting an AR router to a non-Huawei device through an E1 leased line in back-to-back mode
Typical cases of the back-to-back mode are as follows:
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.  NOTE: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 DeviceTypically, 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: Figure 1-8 Connecting to an optical transceiver using a coaxial cable
Figure 1-9 Connecting to an optical transceiver using a twisted pair cable
Figure 1-10 Connecting to an optical transceiver using an E1 protocol converter
