The ADTRAN T3 module combines with other ATLAS components to implement a T3 Bandwidth Manager, sometimes referred to as a 3/1/0 DACS. As a T3 Bandwidth Manager, ATLAS combines the functions of a T3 CSU/DSU, an intelligent channel bank, an M13 Multiplexer, and a DS0-level DACS into a single platform.
ATLAS with T3 support can groom bandwidth presented over the T3 circuit down to the DS0 level. ATLAS supports a wide range of applications including drop-and-insert, channel grooming, and wide-area voice/data/ video transport. ATLAS is ideal for point-tomultipoint configurations or for access to public networks. The T3 module supports drop-and-insert, allowing some of the T3 traffic to terminate in one chassis and other traffic to pass to a second ATLAS system or other channelized T3 product, such as a router.The T3 module occupies a single option slot and can be installed in any ATLAS 800 Series.The T3 module supports network-initiated line loopback at the DS1 and DS3 levels.
