TXC-03453B Description
Each of the three channels of the TL3M can map a DS3 line signal into an STM-1 TUG-3 or STS-3 STS-1 SPE SDH/SONET signal. An E3 signal can be mapped only into an STM-1 TUG-3. The TL3M interfaces to an STM-1 or STS-3 SDH/SONET signal using a byte- wide parallel interface in the TranSwitch Tele Bus format.
