In an effort to deploy next-generation services while leveraging the existing network infra- structures, carriers are looking for solutions that control cost, promote efficiency, and simplify operations. The ADTRAN® Total Access® 1248 is a temperature-hardened DSLAM that enables delivery of up to 48 ports of POTS and ADSL/ADSL2/ADSL2+ from smaller central offices, controlled environ- mental vaults, multiple dwelling units, and remote terminals.

The ADSL/ADSL2/ADSL2+ is generated locally and placed, via onboard splitters, on the same pair as the corresponding POTS signal for delivery to the customer. The

IP DSLAM terminates a Gigabit Ethernet network connection for video and data. This compact, 1U high unit provides RT space savings while offering multiple options for placement within the RT. Design flexibility leverages existing facilities and enables the Total Access 1248 to be mounted as a rack, wall, or vertical positioned unit inside

the RT. It measures 1.75 in. H x 17.25 in. W x 11.125 in. D and offers redundant power using -42 to -56 VDC.

Two different models of the 1248 Mini- DSLAM are available: one with a fixed 10/100/1000Base-T copper Gigabit Ethernet interface or an SFP module interface accepting copper or 1000 Base-X fiber SFP modules. The IP Mini-DSLAMs also incor- porate a wide array of triple-play enabling

features including Bonded ADSL2+, multicast replication, DHCP Option 82, and PPPoE Intermediate Agent. With a standard Gigabit Ethernet interface, the unit is interoperable with any Gigabit Ethernet aggregation switch or router. The Gigabit Ethernet uplink provides a non-blocking architecture to ensure adequate bandwidth for next generation services.

Developed with concern for carrier field needs, the Total Access 1248 has pre-installed fan modules complete with fan filters. Each fan module and fan filter is independently field-replaceable. The fans are controlled by heat-sensing circuits and will run only when necessary. Front panel access is available for all connections.

Management is made simple and conve- nient through a choice of SNMP, ASCII, TL1, or 10Base-T Ethernet support. Provisioning, alarms, and performance monitoring are provided through the local craft interface and IP in-band management channel.

ADTRAN’s Total Access 1248 IP Mini- DSLAM brings cost-effective and efficient ADSL and POTS solutions to carriers providing subscriber services at rural CO, MDU, CEV, and RT sites.
