OC-12 Carrier Access Multiprotocol Label Switching Intermediate Reach Network Interface Module

The Carrier Access / Litton Network Access Systems Broadmore 1750 Asynchronous Transfer Mode (ATM) Multiplexer that enables connection of existing and future services through an ATM network. The Broadmore allows users to implement tailored ATM strategies. This modular system as flexible configurations for service access, network interface, and redundancy.

The Broadmore 1750 functions as an ATM network service access node that supports the transport of existing broadband services (voice, video, and data) over ATM networks. Typically, it is deployed at the edge of an ATM network as the ATM node element closest to the customer. The Broadmore 1750 accepts signals from non-ATM-ready equipment, converts the signals to standard ATM cells, and multiplexes the cells onto a single ATM User Network Interface (UNI) port. The Broadmore 1750 accepts constant bit-rate (CBR) services. Permanent Virtual Circuit (PVC) and Switched Virtual Circuit (SVC) services are available based upon the user-defined module configuration.

The Broadmore 1750 chassis can be configured to perform various functions with plug-in modules. The chassis is manufactured with a passive midplane, (17) slots for modules, and a fan assembly. The Broadmore 1750 midplane also supports 1:N SAM redundancy. Attached mounting brackets are configured for standard EIA 19-inch rack installation. These brackets may be rotated 90 degrees for 23-inch relay rack installation. The chassis has removable front and rear covers, which should remain in place during normal operations. These covers should only be removed to provide internal access for installation, maintenance, or system upgrade.
