TThe Loop-AM3440-E is the latest product in the Loop Access DCS-MUX series that combines various access
interfaces and transport over GbE or E1 uplinks. The Loop-AM3440-E supports SAToP/ CESoPSN/ MEF8 Pseudowire Protocols to transport TDM data streams with timing information over packet switched network.
The Loop-AM3440-E provides full non-blocking DS0 cross-connect matrix for up to 28 x E1/T1 + 64 Bundles. Traffic grooming and segregation between the TDM interfaces and the Pseudowires provides flexibility and efficiency, and makes the Loop-AM3440-E an ideal solution for DACS (Digital Access Cross-Connect System) and ADCB (Add/Drop Channel Bank) applications.
With hot-pluggable mini size slots design, the Loop-AM3440-E provides access for E1, T1, FOM, FXS, FXO, E&M, Magneto*, C37.94, RS232, X.21, EIA530 and V.35 interfaces. These interfaces are compatible with other Loop products.
These application notes cover many aspects of Integrated Access Multiplexer applications. While some are specific to particular products, many are applicable to most any of our channel bank, IAD, or TDM aggregation products. The principles are the same.
We invest a great deal of time and effort creating tools like these to assist our customers, so most are available only to DCB customers. If you are one of our customers and don't have the required customer access password, please contact your sales representative to obtain your free password.
The actual operation of signaling bits used with CAS (Channel associated signaling) for T1 and E1 is is poorly understood by many technicians and engineers. This is a summary of the conventions used for CAS signaling. Download the note in PDF format.
The actual operation of E&M signaling leads is poorly understood by many technicians and engineers. This is a summary of how the AM3440 E&M interfaces operate for Type 1,2,3,4, and 5 E&M configurations. Included are RJ45 E&M Pinouts and descriptions for A-side and B-side installations.

logging capabilities. This paper demonstrates how to configure those features. 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.

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.
