The ADTRAN T3 Module (part# 1200223L1 and 1200225L1 ) 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.

Addressing the wide-area requirements of an industry or business sometimes calls for a large number of T1 circuits to enter a single location. Network access via a T3 circuit, which carries the equivalent of 28 T1 circuits, is often an economical alternative to T1 circuits when requirements exceed as few as eight T1 circuits.

ADTRAN 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-to-multipoint 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 ADTRAN  T3 module(part# 1200223L1 and 1200225L1 ) occupies a single option slot and can be installed in either the ATLAS 800 or the ATLAS 800PLUS Base Unit.

With the T3 Module installed, ATLAS offers extensive monitoring of T3-related parameters and error events. In addition, ATLAS maintains an accumulated count of a number of performance parameters in fifteen-minute intervals. The module can be configured for either M13 or C-bit parity framing. When operating in C-bit parity mode, ATLAS supports a 28.2 Kbps in-band maintenance data link.

The ADTRAN T3 Module supports network-initiated line loopback at the DS1 and DS3 levels.
