Quidway AR 28 Series Routers Installation Manual
I. High-performance processor
Quidway AR 28 Series Routers use high-performance processors to process all the
integrated interface data. All performance indicators, such as packet processing
capacity, maximum traffic on interfaces, delay, frame drop rate, restoration period due
to overloading of the system and system reset period, can meet users' requirements.
II. Multiple interface card/interface module options
Quidway AR 28 Series provides SIC slots and MIM slot, where you can install various
types of SICs and MIMs. The available interfaces include synchronous/asynchronous
serial interface, asynchronous serial interface, T1/CT1/PRI interface, E1/CE1/PRI
interface, BRI S/T and U interfaces, Ethernet interface (including FE/GE, electrical
interface and fiber interface), ADSL/G.SHDSL interface, ATM 25M/155M interface,
E3/T3 interface, and so on. The user can change or extend SICs or MIMs as needed.
Thereby, the investment that has been made can be protected to the maximum degree.
III. Multiple channels of asynchronous serial interface access
Connected to PSTN (Public Switched Telephone Network) via the asynchronous
serial interface, the router can work as a small Internet access server.
With an analog Modem interface card, the router can be directly connected to
PSTN to serve as a small access server.
IV. Ethernet access solution
By extending SICs and MIMs, Quidway AR 28 Series Routers can provide multiple
forms of Ethernet interfaces, such as optical/electrical interface, 10/100/1000Mbps
interface. Thereby, the networking capability of the router can be significantly
improved.
V. Voice capabilities
Quidway AR 28 Series Routers are available with a wide range of voice interface
modules, which can provide such interfaces as FXO/FXS/E&M, E1VI, and T1VI. The
FXS/FXO/E&M interface can connect common phone sets, fax machines and private
branch exchanges (PBXs); the CE1/PRI or CT1/PRI interface can connect the E1 or T1
interface of switches, as well as communicating with the gatekeeper (GK). With
high-speed CPU and digital signal processing (DSP) technology, Quidway AR 28
Series Routers can provide voice over IP (VoIP) and voice over frame relay (VoFR) with
high quality voice. They can drive down the cost of long distance communications
between main office and branches in enterprise deployment.
VI. xDSL/MPLS features
xDSL is a simple but highly-efficient broadband technology that achieves large data
transmission capacity over existing copper wiring by using the digital code modulation
technology. The ADSL/ADSL-I/G.SHDSL module for AR 28 Series allows the
