TXC-03453B TL3M Device Triple Level 3 Mapper

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 Telecom Bus.

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 Telecom Bus format. The TL3M supports Drop bus and Add bus SDH/ SONET timing modes. Drop bus timing provides the timing signals for the add side. Timing for both buses is independent for the Add bus timing mode.
