ALCATEL 3AM20057AB -Lucent MLS-3F Multi-Service Access Node Telecom System Card / Module

The Alcatel 3AM20057AB is a VoIP server control card, designated VIS3-B, for the Alcatel-Lucent MLS-3F access node. This board provides the VoIP signalling and media processing control function for the shelf, converting between the access node’s narrowband subscriber line cards and IP/VoIP transport, so that MLS-3F shelves provisioned for next-generation network operation can continue to deliver voice services over an IP-based core. It works alongside NGN-oriented interface cards such as the GIO3 GE I/O card and narrowband extender cards such as the NSEC-C in the same shelf, and is a control/processing card rather than a subscriber-facing line card. MLS-3F is part of the same Alcatel-Lucent Litespan/Multi-Service Access Node family used to deliver copper-based narrowband and broadband services to residential and business subscribers. Tech-Star (UK-based, shipped worldwide) supplies tested MLS-3F access node cards; contact our engineers to confirm compatibility with your shelf configuration before ordering.
