Asynchronous Interfaces

Asynchronous interfaces, also known as terminal ports, (labelled ASYN0, ASYN1, RS-232 or CONSOLE) use RJ-45 connectors, wired as DTE with one of two pinout wiring schemes:

■For AR725, AR745 and AT-AR024 asynchronous port pinouts see Table 8.

■For AR750S, AR750S-DP and AR770S asynchronous port pinouts see Table 9.

Asynchronous interfaces follow the RS-232 standard. A range of speeds is selectable using the set asyn command from the Interfaces chapter of the Software Reference.

Not all signals need to be connected. In particular, DCD, DTR, CTS and RTS are not required unless the interface has been specifically set up to use them. See the Terminal Server chapter in the Software Reference for more details. A typical terminal connection will only require RXD, TXD and GND, but refer to the equipment manual for the connected device for more specific data.

LPD print ports If LPD-based printer ports are required, then the router may expect to ‘see’ the DTR signal from the printer connected to the DCD pin of the router. This is used to detect both the fact that the printer is ‘online’ and that it

AR700 Series specifications

The Allied Telesis AR700 Series represents a robust line of edge routers engineered for high-performance networking. These devices are aimed at delivering versatility and scalability, catering to the needs of various organizations, whether small businesses or larger enterprises. Known for their reliability and advanced features, the AR700 Series stands out as a compelling option for organizations seeking to enhance their network infrastructure.

One of the standout features of the AR700 Series is its support for advanced routing protocols. The routers are capable of handling various protocols such as OSPF, BGP, and RIP, ensuring seamless integration within diverse network environments. This capability allows organizations to efficiently manage their routing needs, optimizing data flow for enhanced performance.

In addition to its routing protocols, the AR700 Series supports powerful Quality of Service (QoS) features. This technology prioritizes network traffic based on specific requirements, ensuring that vital applications receive the necessary bandwidth. This is particularly important for businesses that rely on real-time services such as video conferencing or voice over IP (VoIP), where uninterrupted service is critical.

The AR700 Series is also equipped with advanced security features to safeguard against cyber threats. With built-in firewall capabilities, VPN support, and traffic filtering, these routers help protect sensitive data from unauthorized access and attacks. Additionally, the ability to implement VLANs (Virtual Local Area Networks) further enhances the security and manageability of the network.

Scalability is a key characteristic of the AR700 Series. Organizations can easily expand their network capabilities as they grow, with support for various interface modules. This flexibility enables businesses to adapt their infrastructure without the need for complete overhauls, making it a cost-effective solution in the long run.
