Networking Requirements

Networking Requirements

As shown in Figure 1, the enterprise branch and headquarters are connected through a transmission network. E1 links are provided on the transmission network to connect to the branches, and optical fibers and optical transceivers are used to connect to the enterprise network. To be specific, RouterA is the gateway of the enterprise branch and is connected to optical transceiver 1 through an E1 leased line. RouterB is the gateway of the headquarters and is connected to optical transceiver 2 through an E1 leased line. The optical transceivers are then connected to the transmission network using optical fibers.

The customer can select appropriate E1 interface cards and E1 cables based on the device requirements and network environment. This example uses two-port 2E1/T1-M interface cards that work in E1 mode. 2E1/T1-M interface cards work with DB9 connectors, while optical transceivers work with RJ45 connectors. 120-ohm DB9-to-RJ45 cables can be used to connect 2E1/T1-M interface cards with optical transceivers, which are then connected to the transmission network, enabling data transmission between the branch and the headquarters.
