The Adtran Total Access 1500 Dual T1 Line Interface Unit (LIU) is a common module plug-in unit that connects the channel bank to a T1 line at the DSX-1 level. All data formatting and line encoding, as well as backplane timing and control, are performed by the ACT LIU. The LIU can be provisioned locally with on-board switches, remotely through the SCU craft interface or remotely through network management. The on-board switches are a subset of the provisioning parameters. All parameters are available when provisioning through the craft interface. A faceplate LED indicates whether the LIU operation mode is based on local or remote provisioning parameters. A dual bantam jack located on the faceplate provides test access of the T1 data stream.

The Dual T1 LIU offers up to two T1s of network bandwidth for POTS and special services deployment from the Total Access 1500. The Dual LIU can be deployed in a universal COT/RT configuration or in an integrated RT-only configuration. When used in a universal configuration, the Dual LIU provides 48 DS0s of POTS and special services. When used in an integrated configuration, the Dual LIU will support up to 48 POTS circuits. Adtran's new Carrier Class multiservice access platform, Total Access 1500, offers unmatched versatility for narrowband service offerings in the smallest form factor available. The platform integrates the functionality of many different carrier products into a single chassis. It features high density, easy provisioning, flexible deployment, and low cost-per-port. Deployed in either the central office or remote terminal, Total Access 1500 provides a fast, simple and effective means of increasing POTS capacity, deploying special services and deploying DSL services.
