The Excalibur™ Multirate Digital Access Product (DAP) provides superior multirate performance over all digital data services (DDS), including Frame Relay. This versatile, user-friendly unit operates in both point-to-point and multipoint networks at speeds from 2.4 to 64 Kbps.

Multimode Versatility
The Excalibur Multirate DAP offers the versatility to change between services as your needs and tariffs change. Choose from several options:

Multiport/Multidrop Compatible
The Excalibur Multirate DAP can be connected to a multidrop network made up of Excalibur Multiport DAPs, and can interface to any one channel in the aggregate data stream. The unit can operate as a multidrop central or remote.

Central Site and Standalone Models
Designed for your central locations, the central site model installs in the high-density Excalibur Card Carrier. Each card carrier can hold up to 16 units. Ideal for remote site applications, the standalone model comes in a compact case that fits wherever your needs dictate.

Dial Backup Options
In the event your network or digital lines go down, the Excalibur Multirate DAP offers dial backup options. Whether you choose analog lines, Switched 56, or ISDN backup, this option can keep your operation up and running. The dial backup connections can be established automatically or manually.

Full Management via SNMP
The Excalibur Multirate DAP can be fully managed via SNMP. Its integral MIB-II-compliant SNMP agent provides a standards-based management interface, enabling you to manage your entire network with any SNMP-based management application. Full Telnet client support is included. Should you not have access to an SNMP manager, an optional Windows-based front panel emulation software package is available.

For SNMP support, the DAP provides a synchronous or asynchronous PPP/synchronous SLIP interface. For standalone units, an optional Ethernet interface is available. With a direct Ethernet connection to the LAN, you save the expense of dedicating an expensive port from the router or providing an additional LAN server to route your SNMP traffic.

Custom SNMP Management Application
To simplify management, Milgo offers a custom SNMP management application that runs on the CMS® 400 platform. This application provides an intuitive graphical interface specifically tailored for the Excalibur DAP. You can use this application to fully configure the DAP, monitor its performance, view extended network-wide statistics, and integrate traps.


Excalibur™ Multirate DAP Technical Specifications

Line Requirements Operates over all Digital Type 1 services and Clear Channel 64 Kbps services; can alsooperate over customer-owned copper wire.
Dial Backup Options Connections: 2-wire 14.4 or 28.8 Kbps analog, 4-wire Switched 56 Kbps, or 2-wire Integrated Services Digital Network (ISDN).

14.4 Kbps analog dial backup operates in Programmable or Permissive mode, supports V.32 or V.32 bis+ (Milgo proprietary mode with non-interruptive secondary channel) format.

28.8 Kbps analog dial backup operates in Programmable or Permissive mode and provides V.34 modemsupport.

Switched 56 dial backup operates at 56 Kbps over MCI's Switched 56 Service, AT&T's Accunet Switched 56 Service, or Sprint's Enhanced Switched 56 Service.

ISDN dial backup operates at 56 or 64 Kbps over ISDN Basic Rate service. It complies with all applicable specifications, including National ISDN-1 standard, Northern Telecom Basic Rate Access, and AT&T Basic Rate Access. It can operate with another DAP equipped with Switched 56 dial backup, providing backup to locations where ISDN service is unavailable.
