Compare Adtran TSU 600e™ Multiplexer (1202076L1 #DC) to Adtran ISU™ 512 Multiplexer (1202086L1)

The TSU 600e is the modular, full-featured T1/FT1 Multiplexer designed to support a wide range of end-user applications. Through the six expansion slots on the rear of the TSU 600e, the user has complete flexibility in the type of DTE interfaces required for the T1 application. By supporting up to 24 DTE interfaces, the TSU 600e provides the same functionality as a traditional channel bank, while providing a small form factor and end-user oriented features. The TSU 600e provides complete monitoring and control of internal functions with embedded Simple Network Management Protocol (SNMP) provided through a SLIP interface. ??The TSU 600e has the added benefit of an integrated 10BaseT Ethernet interface. To support critical applications, the TSU 600e also has the capability to support dual redundant power supplies internally. The power supply module is capable of supporting a fully loaded TSU 600e and is hot-swappable. Less

The ADTRAN ISU 512 is a standalone ISDN Service Unit that connects data terminal equipment (DTE) to the ISDN network. The ISU 512 is specifically designed as a low-cost solution for applications such as video-conferencing, T1 backup, LAN/WAN connectivity, and high-speed file transfer.? ?The ISU 512 is designed as a cost-effective inverse multiplexer for 384 kbps videoconferencing. Some video-conferencing products operate in a dual port mode. The ISU 512 is designed to operate in a dual port mode making it backward compatible with videoconferencing systems utilizing two Switched 56 DSUs or a dual port ISDN terminal adapter. The ISU 512 connects directly to the ISDN network using up to four Basic Rate ISDN (BRI) lines. By terminating four BRI circuits, the ISU 512 can create an aggregate bandwidth of up to 512 kbps which can be used to backup a T1 circuit. Since ISDN is a switched digital service, bandwidth can be established and utilized on an as needed basis. Therefore, the ISU 512... Less
