This feature extends the number of T1/E1 spans supported by SBC 1000 from 2 to 4 spans with the addition of a second T1/E1 line card. Previously the SBC 1000 supported one 2-port T1/E1 line card with the first T1/E1 port being licensed by default and the second port controlled by a software license. In this release, the first port is licensed by default, and the next three ports are configurable through software licensing.
The additional 2-port T1/E1 line card (slot 8) is accessed through two ports (labeled 1 and 2) on the left side of the SBC 1000 Front Panel.
