Thiết bị PCM 30 AM3440-B

The AM3440-B is the smallest of all the AM3440 chassis. At 2.5U and with 4 mini-slots and just 3 single slots, this device is ideal for customers needing a smaller-scale access DCS-MUX.


The Loop-AM3440-B is a small access DCS-MUX that combines various digital access interfaces into E1or T1 lines for convenient transport and switching. This device provides access for a variety of TDM, IP, and voice interfaces that are compatible with a variety of other Loop products. Using these products, a DTE interface can be extended over copper wire pairs or any E1/T1 transport facility. Each Quad E1/T1 plug-in card can have as many as DS0 124/96 time slots from G.SHDSL, RS232, X.21, V.35, V.36 and EIA530 / RS449 interfaces, which can be multiplexed to fill 4 E1/T1 lines. The AM3440 also supports fiber optical plug-in cards, which can be used to aggregate up to 4 E1 channels onto a single fiber optical interface to connect with other AM3440 devices or with the O9310-E1. With a number of plug-in slots in single slot size and mini size, this unit can be fully configured to any user's needs.

The AM3440-B is a full cross-connect and can act as a mini DACS; 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. The chassis does not need fan cooling, and thus does not have a fan, though an external fan tray is available.

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, Telnet, and SNMP so that it can be controlled and diagnosed from remote locations. An in-band management channel with GUI is available. In addition to the LCD display, there is LED indication for all plug-in cards.

The AM3440 consists of a rugged reinforced aluminum chassis, giving this equipment a more durable structure and a longer physical life.
