The ADTRAN Total Access 1500 Line Interface Unit 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 full set of 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 Quad T1 LIU offers up to four T1s of network bandwidth for POTS and special services deployment from a Total Access 1500. The Quad LIU can be deployed in a universal COT/RT configuration or in an integrated RT-only configuration. When used in a universal configuration, the Quad LIU provides 96 DS0s of POTS and special services. When used in a integrated configuration, the Quad LIU will support up to 96 POTS circuits. The Quad LIU provides both facility and equipment protection. In the universal configuration, a fifth T1 is available for facility protection. Additionally, two Quad LIUs can be deployed in a single Total Access 1500 chassis to provide equipment protection.
