Access DCS-Mux

LOOP-AM 3440

Access DCS-MUX

Description

The Loop-AM 3440 is an access DCS-MUX that can combine various digital access interfaces into E1 or T1 lines for convenient transport and switching. The Loop-AM 3440 Access DCS-MUX provides access for a variety of interfaces, including Quad E1/T1, 10/100baseT Router, MDSL, U type (ISDN), RS232, V.35, E&M, FXS, and FXO. These interfaces are compatible with other Loop products such as the Loop-H 3900 (MDSL) and the Loop-U 3500 (U). Using these products, a DTE interface can be extended over RS232 copper wire pairs. Up to 120 time slots for the MDSL, U, RS232 and V.35 interfaces are then multiplexed to fill an E1 or T1 line, with full flexibility of time slot interchange.

This unit is a full cross-connect and can act as a mini DACS. This means that one or more of the WAN ports can be used as a Drop & Insert function with fractional E1/T1 lines, which can be muxed into a full E1/T1 line.

Redundancy is available in dual CPU controller and power supply options, making it an excellent fit for critical applications. And, though the chassis does not contain and has no need for fan cooling, a fan tray is available.

The Loop-AM 3440 supports local control and diagnostics by using an external 2-line by 40-character LCD display and keypads, or by using a VT-100 terminal connected to the console port. The Loop-AM 3440 also supports Ethernet, SLIP, Telnet, and SNMP, so that it can be controlled and diagnosed from remote locations as well. An in-band management channel with GUI are available. In addition to the LCD display, there is LED indication for all plug-in cards.

Finally, the Loop-AM 3440 consists of a rugged chassis made from reinforced aluminum, giving this equipment a more durable structure and a longer physical life.
