Carriers are seeking cost-effective DSLAM solutions to meet demand for additional

customer applications. The ADTRAN Total Access 1250 is a temperature-hardened Mini- DSLAM that enables delivery of 24 ports of POTS and ADSL via an Ethernet 10/100Base-T interface from smaller Central Offices (COs), Controlled Environmental Vaults (CEVs), Multiple Dwelling Units (MDUs), and Remote Terminals (RTs). The ADSL is derived from the network interface and is combined via onboard splitters with the existing POTS service for single-pair subscriber delivery.

The Total Access 1250 offers a scalable network interface today with the Ethernet interface module. The IP interface module supports 1483/2684 bridging via either LLC/SNAP or VC MUX encapsulation. Statistics are collected on both the subscriber and network ports.

The compact, 1U high unit provides space savings while offering multiple options for placement within compact environments. Its design leverages existing telco resources and can be rackmounted, wallmounted, or verti- cally positioned within the RT. It measures

4.45cm H x 43.82 cm W x 28.26 cm D and offers redundant power using –42 to –56 VDC.

The Total Access 1250 is equipped with fan modules and filters. Each fan unit is inde- pendently field replaceable. The fans are controlled by heat-sensing circuits and will run only when necessary. Front panel access is available to all connections.

The ability to connect to the Total Access 1250 via an IP uplink at the customer prem- ises immediately improves the economics of broadband for businesses such as hotels, service-based organizations, and small-to- mid-sized enterprises (SMEs). Carriers benefit by expanding IP in their existing networks without costly ATM server installations. This is especially true for network applications that do not require the expense associated with ATM-QoS. In these cases, IP is more ubiqui- tous and cost-efficient for both intra- and inter-network operations.

Management options include SNMP, ACSII, TL1, Telnet, or local VT100 interfaces. Menu-driven interfaces are simple and intu- itive, ensuring a successful service implementation through local and remote access.

ADTRAN’s Total Access 1250 Mini-DSLAM brings cost-effective and space-efficient ADSL with POTS solutions to carriers providing subscriber services at rural CO, MDU, CEV, and RT sites.
