Multi-service Access Node TDM / IP - AM3440-A-CHPAa

دانلود ها

The Loop-AM3440-A product is Access DCS-MUX which supports multiplexing of various digital access interfaces into E1 or T1 lines for convenient transport and switching. The Loop-AM3440-A Access DCS-MUX provides access for a variety of TDM, packet, and voice interfaces detailed on the next page. These interfaces are compatible with other Loop products. The AM3440-A 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 controller module provides full non- blocking Nx64K cross-connect matrix up to 2048 DS0. System redundancy is available in dual controller and power modules, making it an excellent fit for critical applications. With Loop-AM3440-CCPB-8GEHSWa controller module, it supports both MPLS-TP* and Carrier Ethernet functions as Packet Transport Network. In addition to the native Ethernet transport, the AM3440 can be used as the gateway of PDH into the PSN network using circuit emulation technologies. The TDM encapsulation technologies supported are TDMoE, TDMoIP, and TDMoMPLS*. In parallel, the Circuit Emulation supported are CESoPSN (Nx64K) and SAToP (Unframed E1/T1).

While 1+1 link protection is available for E1, T1, and TDMoEA* modules, path protection for end-to-end Nx64K circuit protection is available for 3E1/T1.

The AM3440-A supports local control and diagnostics by using a VT-100 terminal connected to the console port. It supports Ethernet, Telnet, and SNMP, so that it can be controlled and diagnosed from remote ends. An in-band management channel with GUI is available as well.

Loop-AM3440-A has a number of plug-in slots in regular size and mini size. (Card size to slot compatibility is detailed on the next page.) Most of the plug-in cards have LED indications.

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