MADGE SYNCHRONOUS DATA INTERFACES

The Madge QRVX and DRVX synchronous data interfaces are plug-in modules that can be inserted in either the Madge AccessSwitch 60 (6 slot) or AccessSwitch 200 (20 slot) chassis. The QRVX module provides four synchronous interface ports and the DRVX module provides two. Each module can be configured as a group of RS449 or V.35 interfaces, with RS366, RS366A, V.25 bis or X.21 dialing for videoconferencing

Customer Benefits

• Easy connection of industry standard RS449 or V.35 devices
• Optional inverse multiplexing allows use of multiple B channels
• Local, national, and international dialing plan capability

Product Features

• 4 T1 RS449 or V.35 synchronous connections
• Built-in RS366/RS366A interface ports for V.25bis or X.21 dialing
• Supports standard data rates from 56 Kbps to 1,539 Kbps

•  Features

Family of Modules
The Madge QRVX and DRVX synchronous interface are single plug-in modules for the Madge AccessSwitch slotted hubs (six- or 20-slot chassis). The QRVX and DRVX are part of the Madge family of interface modules that provide input/output connections between external synchronous devices and any other modules installed in the AccessSwitch chassis. Modules can be used in any combination to provide powerful call switching capabilities among T1, ISDN Basic or Primary Rate, or E1 Primary Rate trunking, and RS449/V.35 synchronous interfaces with RS366, V.25bis, or X.21 dialing.

Industry Standard Support
The QRVX module provides four synchronous interface ports, and the DRVX module provides two. They both can be configured as RS449, V.35, or X.21 interfaces, with RS366, RS366A, V.25 bis or X.21 dialing. Standard data rates supported include single B channel (56/64 kbps), H0 (384 kbps), and H10 (1,472 Mbps). The modules can also support the H11 (1,536 Mbps) data rate using Non-Facility Associated Signaling (NFAS). Optional inverse multiplexing (IMUX) software allows the use of multiple B channels to support a wide range of data rates.

•  Key Benefits

The Madge QRVX and DRVX modules provide input/output connections and support for high-speed digital CPE.

Easy Expansion
Multiple QRVX or DRVX modules can be supported in the same AccessSwitch base unit for applications requiring more synchronous ports. The AccessSwitch 200 chassis can accommodate up to 19 modules for a maximum of 76 synchronous connections. A maximum of five modules can be supported by the AccessSwitch 60 chassis for a maximum of 20 synchronous connections.
