Modular, full-featured platform designed to support several functions associated with GR-303 concentration
Can terminate up to 128 T1s (DSX-1 format) with the flexibility of assigning any T1 as an input from the switch or as a concentrated output to the user
Provides connectivity for up to four DS3 or STS-1 interfaces, providing additional flexibility for connection to the switch or to the network

The Total Access 4303 is a modular, full-featured platform designed to support several functions associated with GR-303 concentration. The system can terminate up to 128 T1s (DSX-1 format) with the flexibility of assigning any T1 as an input from the switch or as a concentrated output to the user. The Total Access 4303 also provides connectivity for up to four DS3 or STS-1 interfaces, providing additional flexibility for connection to the switch or to the network. The unit utilizes full digital cross-connect functionality, allowing the separation of non-concentrated data circuits from concentrated voice circuits for mixed mode applications.

Built for NEBS compliance, and offering full power redundancy and full controller redundancy, the Total Access 4303 supplies the protection required by the Competitive Provider. With front-inserted modules and rear panel connectivity, the unit is suited for rack or wall mounting and easy access in the field. With full alarm reporting, extensive test functions, and a complete set of management features, the Total Access 4303 is suited for a remote, non-manned Point of Presence (POP). By offering an easy to use, menu-driven interface and the capability to test and provision a downstream ADTRAN Total Access 850 IAD, the Total Access 4303 is designed to minimize truck rolls and service calls. Additionally, for deployment options, the Total Access 4303 can be coupled with the ADTRAN Total Access 3000 for HDSL, HDSL2, and SDSL access to unbundled network elements (UNE).
