The Loop-AM3440-D is the latest product in the Loop Access DCS-MUX series that combines various digital access interfaces into E1 lines for convenient transport and switching. With 9 hot-pluggable mini size slots design, the Loop-AM3440-D provides access for a variety of TDM, IP, and voice interfaces. These interfaces are compatible with other Loop products.
Using these products, a DTE interface can be extended over copper wire pairs or any E1 transport facility. For each mini Quad E1 plug-in card, each card can have as many as DS0 124 time slots from RS232, X.21, V.35, and EIA530 interfaces, which can be multiplexed to fill 4 E1 lines. The AM3440-D 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 O9310 devices.
The AM3440-D has 9 mini size plug-in slots. The plug-in cards are compatible with all mini size of AM3440-A/B/C series.
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 lines, which can then be multiplexed into a full E1 line.
Redundancy is available in dual CPU controller and power supply options, making it an excellent fit for critical applications. The chassis does not contain and has no need for fan cooling.
The Loop-AM3440-D supports local control and diagnostics by using an external 2-line, 40-character LCD display and keypads, or by using a VT-100 terminal connected to the console port. The Loop-AM3440 also supports Ethernet, Telnet, and SNMP so it can be controlled and diagnosed from remote locations. An in-band management channel with GUI is available.
The Loop-AM3440-D consists of a rugged reinforced aluminum chassis, giving this equipment a durable structure and a long physical life.
Most Loop V-4200 cards are compatible with the AM-3440-D chassis.

This is a "cheat sheet" with information that helps you get started mapping the AM-3440. These DACS have lots of flexibility and these hints will save you time getting them configured. Download the note in PDF format.
If an AM3440 with redundant controllers has a loss of one of the controllers, it is a simple procedure
to replace the failed controller. Just install the new controller in place of the failed controller in a hot swap procedure. No need to power down the system to replace
a failed controller. This note discusses how to manage differing firmware versions in this situation.Downlaoad the note in PDF format.
This is an example procedure mapping with information that helps you get started mapping the AM-3440. This exmaple illustrates mapping and a loop back test to verify correct operation. These DACS have lots of flexibility and these hints will save you time getting them configured. Download the note in PDF format.
The procedure for updating firmware in an AM-3440 having dual controller cards may be daunting. This paper details a straight forward method for that procedure. Download the note in PDF format.

A question about pass through voice DS-0 circuits was recently raised. Loop product mapping provides a choice of "d" for data or "v" for voice to be designated for each DS-0. FXS, FXO and E&M circuits must all be set to "v" for voice. If a DS-0 carrying voice passes in and out of a T1 as a pass through, must this be set to "v" for voice? The answer is "yes". See this paper for details on setting a pass through DS-0 to "v" for voice and for verifying the setting. Download the note in PDF format.
