Description

The ADTRAN® Express 5200 is a family of Frame Relay access devices that provide a cost-effective means of transporting voice and multi-protocol data over Frame Relay and point to point networks. For customers looking for disaster recovery solutions, the units provide optional dial backup.

The Express 5200 series is an economical means of providing high-quality voice and fax capabilities to remote locations without expen-sive toll charges. Voice options are supported through plug-in voice cards. Voice and data can share the same Permanent Virtual Circuit (PVC) eliminating unnecessary PVC charges.

The Express 5200 provides multi-protocol support through two serial interfaces that can support EIA-232 and V.35 operating at rates from 2.4k to 512k. The series supports SNA, SDLC, SLIP, IP, PPP (both synchronous and asynchronous), Frame Relay, BOP, and asynchronous protocols. The DTE ports can be configured independently, providing support for multi-protocol applications. The Express 5210 provides the same multi-protocol support through a single serial interface but also includes an integrated 10BaseT Ethernet port that supports full IP routing.

The Dial Backup (DBU) feature allows automatic or manual backup upon interruption of Frame Relay or DDS services. The addition of DBU is accomplished through plug-in cards: 4-wire Switched 56, V.34 modem, and 1B+D ISDN.

The units monitor both the physical link and the Frame Relay signaling to determine if an interruption has occurred. Once detected, the host unit initiates a dial-up call around the Frame Relay network and merges backup traffic, with the primary traffic still being received from unaffected remote sites. The DTE device still receives all data as Frame Relay traffic, allowing a transparent backup transition. Once the failed condition has been cleared and the Frame Relay interruption is over, the unit automatically restores traffic to the primary link. In addition to voice and dial backup, the Express 5210 also supports IQ Frame Relay performance monitoring. This includes statistics on throughput and utilization per port and PVC; availability; lost frames and PVC state; excess bursting above CIR; network congestion (FECN, BECN, and DE); and end-to-end delay on any or all PVCs. SNMP is provided with support for RFC 1315 and MIB II. The units can be configured, monitored, and diagnosed using standard SNMP network management programs such as HP OpenView, IBM’s NetView, and SunNet Manager. Complete control, configuration, and diagnosis are available through a 16-position keypad and a two-line by 16-character LCD display. VT100 terminal configuration and control mode are also available through the control port. Flash download capability is implemented for installation of new features and enhancements.
