Carriers are seeking DSL solutions that deliver broadband simply and reliably to their valued customers. In order to make DSL delivery a business success, carriers need solutions that control costs, simplify management, and provide advantageous support systems. The ADTRAN Total Access 1200 Series of Mini-DSLAMs were designed with service providers in mind. With low start-up costs and the ability to scale for future applications, the Total Access 1200 Series offers the advantages carriers need to make DSL affordable and maintainable.
The Total Access 1200 Series of Mini- DSLAMs are temperature-hardened, 1U high mini-DSLAMs that enable delivery of 24 ports of POTS, ADSL, and IP Ethernet service from smaller Central Offices (COs), Controlled Environmental Vaults (CEVs), and Remote Terminals (RTs). Design flexibility enables the Total Access 1200 Series to be mounted as rack, wall, or vertical positioned units inside existing enclosures. The units measure
4.45cm H x 43.82 cm W x 28.26 cm D and offer redundant power using –42 to –56 VDC.
The series consists of:
•Total Access 1210: 24-port ATM Quad IMA network interface
•Total Access 1211: 24-port ATM Quad IMA network interface with expansion option
•Total Access 1250: 24-port IP Ethernet network interface
In the Total Access 1210 and 1211 models, the ADSL is generated locally and merged via onboard splitters, on the same pair as the corresponding POTS signal for delivery to the customer. The Total Access 1200 Series models offer a scalable network interface Quad IMA module with future capabilities for Octal IMA, DS3 and STM-1. The modules assure easy deployment and dynamic network utilization as subscriber needs dictate. These Mini-DSLAMs perform Inverse Multiplexing over ATM (IMA) for up to four E1 IMA links in a single unit. The units can scale into a system-wide RT solution by using the Total Access 1200 expansion feature to deploy multiple shelves at a single location.
The Total Access 1250 supports IP Ethernet services to end-user customers. The economics of broadband delivery are imme- diately improved for both carriers and customers, especially businesses such as hotels, service-based organizations, and small-to-mid-sized enterprises. Carriers benefit by expanding IP services in their existing networks without costly ATM server installations. This is very true for network applications that do not require the expense associated with ATM-QoS.
Developed with ADTRAN’s concern for carrier field needs, the Total Access 1200 Series have two pre-installed fan modules complete with fan filters. Each fan module and fan filter is field replaceable. The fans are controlled by heat-sensing circuits and will only run when necessary. Additionally, all connections have front panel access.
