In an effort to deploy next-generationservices while leveraging the existing network infrastructures, carriers are looking for solutions that control cost, promote efficiency, and simplify operations.The ADTRAN® Total

Access® 1248 is atemperature-hardenedDSLAM that enables delivery of up to 48 ports of POTS and ADSL/ADSL2/ADSL2+ from smaller central offices, controlled environmental 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 -42to-56VDC.

Two different models of the 1248 MiniDSLAM are available: one with a fixed 10/100/1000Base-Tcopper Gigabit Ethernet interface or an SFP module interface accepting copper or 1000Base-Xfiber SFP modules. The IPMini-DSLAMsalso incorporate a wide array oftriple-playenabling

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-blockingarchitecture to ensure adequate bandwidth for next generation services.

Developed with concern for carrier field needs, the Total Access 1248 has pre-installedfan modules complete with fan filters. Each fan module and fan filter is independentlyfield-replaceable.The fans are controlled byheat-sensingcircuits and will run only when necessary. Front panel access is available

for all connections.

Management is made simple and convenient through a choice of SNMP, ASCII, TL1, or 10Base-TEthernet support. Provisioning, alarms, and performance monitoring are provided through the local craft interface and IPin-bandmanagement channel.

ADTRAN’s Total Access 1248 IP Mini-

DSLAM brings cost-effectiveand efficient

ADSL and POTS solutions to carriers providing subscriber services at rural CO, MDU, CEV, and RT sites.
