Adtran T3 Concentration/Grooming

ATLAS
The ATLAS Series of IADs offers the highest capacity and most advanced set of networking services. From a single platform, ATLAS can support multiple technologies including T1, T3, ISDN, IP routing, and Frame Relay. IT managers and network engineers of small, medium and large enterprise networks may choose ATLAS for its ISDN conversion and oversubscription features, T1 Inverse Multiplexing, ISDN PRI/BRI switching, multiple T1/PRI DACSing and grooming, Frame Relay concentration/switching, compressed voice, T3 applications, and videoconferencing.

This multi-T1/PRI enterprise platform converges voice, data, video, and Internet traffic through dynamic bandwidth allocation, T1 Inverse Multiplexing, circuit switching, and packet routing. The ATLAS 550 is designed for the small-to-medium networks with one to 18 T1/PRI ports, while the ATLAS 830 is designed for medium-to-large networks that require up to 34 T1/PRI ports or a T3. The ATLAS 890 supports up to 64 T1/PRI ports or a T3 and can be used in networks that require full system redundancy.

For global applications, the ATLAS Series also offers a range of interfaces including E1, ISDN PRA and BRI S/T, along with support for Net-3 and Net-5 Euro-ISDN protocols.

Total Access 4303
ADTRAN's Total Access 4303, a GR-303 concentrator with digital cross-connect capability, is a low-cost platform that allows services to be delivered to a highly distributed customer base from a single switch -- without sacrificing bandwidth.

Total Access 4303 supports voice concentration ratios from 1:1 to 16:1 and can be used in the Central Office as a GR-303 concentrator (128 DSX-1 port capability) or as a 3/1/0 cross-connect supporting multiple IADs.

Supports DSX-1, STS-1, or DS3 network or switch interfaces.
