Thiết bị ghép kênh PCM-30 Loop AM-3440-B

Model: AM-3440-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-A/B/C series are Access DCS-MUXs that combine various digital access interfaces into E1 or T1 lines for convenient transport and switching. The Loop-AM3440 Access DCS-MUX provides access for a variety of TDM, IP, and voice interfaces detailed on the next page. These interfaces are compatible with 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

Each of the 3 models of AM3440-A, B, and C has a number of plug-in slots in single slot size and mini size. Card size to slot compatibility is detailed on the next page.

This unit 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.

The AM3440 supports local control and diagnostics by using a VT-100 terminal connected to the console port. There are LED indications for all plug-in cards. 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.

The AM3440 consists of a rugged reinforced aluminum chassis, giving this equipment a durable structure and a long-lasting physical life.
