The AM3440-A/B/C is an access DCS-MUX that can combine various digital access interfaces into E1 or T1 lines or Ethernet networks for convenient transport and switching. The AM3440 Access DCS-MUX provides access for a variety of interfaces, including TDMoE, mini Quad E1, Quad E1/T1, ATM/FR, 32 WAN port Router, 64 WAN port Router-A, Router-B, FOM, Terminal Server Card, G.SHDSL, G.703, U type, X.21, V.35, V36, EIA530/RS449, RS232, 8RS232, QEM, QFXO, QFXS, 8EM, 12FXS, 12FXO, 24FXS, 24FXO, and Magneto. These interfaces are compatible with other Loop products such as the Loop-H 3900 (MDSL), LoopH3300 and the Loop-U3500 (U). Using these products, a DTE interface can be extended over copper wire pairs. For as many Quad E1/T1 plug-in cards, each card can have as many as 124/96 time slots for the G.SHDSL, U, RS232, X.21, V.35, V.36 and EIA530/RS449 interfaces are then multiplexed to fill 4 E1/T1 line, with full flexibility of time slot interchange for all incoming lines. AM3440 also supports fiber optical plug-in module, which can be used to aggregate up to 4 E1 channels to single fiber optical interface to connect with other AM3440 or O9310.
AM3440-A has capacity for 12 single slots and 4 mini plug-in slots. AM3440-B has capacity for 3 single slots and 4 mini plug-in slots. AM3440-C has capacity for 5 single slots and 4 mini plug-in slots. All interface cards and controller cards can be used in AM3440-A/B/C, except for the G.SHDSL line power card, which is for the AM3440-A only and mini-slot QEM/QFXS/QFXO interface cards, which are for the AM3440-B and AM3440-C only.
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. The larger chassis supports 64 T1 connections.
Redundancy is available in dual CPU controller and power supply options, making it an excellent fit for critical applications. Although the chassis does not contain and has no need for fan cooling, an external fan tray is available.
An economical teleprotection transfer trip interface is also available. Remote Transfer Trip is commonly used in the power industry where high speed remote alarming is required, but also finds use in remote alarming applications in other industries.
The AM3440 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 AM3440 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 is available. In addition to the LCD display, there are LED indications for all plug-in cards.
