QUAD E1/PRA

ATLAS MODULE

The Quad E1/PRA Module combines with other ATLAS components to implement a variety of WAN access solutions, including serving as an E1 Bandwidth Manager and Digital Access Cross-Connect System (DACS). The module provides four E1 ports, each of which can be separately configured.

ATLAS has the ability to support time slot interchange and to digitally cross-connect, or DACS, up to 32 E1 circuits. Any DS0 of any E1 can be groomed and mapped to any DS0 of any other E1 in the system.

With the E1 module, ATLAS can act as a concentrator of 64/128 kbps leased lines. The ATLAS Quad E1/PRA module will work in conjunction with the Octal BRI module and allow users to map BRI ports to E1 DS0s in a dedicated, leased line application.

The Quad E1/PRA module can also be used with the ATLAS 800^PLUS to support public and private Frame Relay solutions. The ATLAS 800PLUS includes a 10BaseT Ethernet port and IP Router to encapsulate data into Frame Relay packets. External routers can also be connected to the ATLAS 800^PLUS through one of the many optional serial interfaces including: V.35, EIA-232, EIA-530, EIA-449, X.21 and V.36.

Configuration of the Quad E1/PRA Module can be accomplished through Telnet or VT 100 emulation. SNMP management is supported for alarm and event reporting.

Extensive performance monitoring is standard with the Quad E1/PRA module to detect and record Loss of Signal, Loss of Framing, CRC4, AIS, REM and REMF.

When testing the E1 circuit, the system allows the user to select loopback commands and test patterns, including All 1s and All 0s as well as QRSS pattern.
