Manufacturer's product description
The Larscom Mega-T 241 transports E1 traffic over two T1 lines, as shown in Figure 1. It can connect an E1 multiplexer, channel bank, or PBX directly to a public or private T1 network. Or it can extend an E1 circuit across a T1 network. Larscom's proprietary inverse-multiplexing technique (for which a U.S. patent has been issued) ensures that demultiplexing and remultiplexing of the E1 signal is completely transparent to the application. The Mega-T 241 will compensate for up to 125 milliseconds of differential delay between the two T1s. In addition to transporting E1 traffic through T1 networks, the Mega-T 241 provides extensive performance monitoring and diagnostics to facilitate network management. An RS232 terminal interface allows local or remote management of all Mega-T functions.
