It provides a fully non blocking cross connect for 3024 VT1.5's that are all frequency, phase and column aligned in addition to a pregrooming 2:1 UPSR selection. The device receives 9 x 622 Mb/s STS-12 working and protection backplane inputs and performs all necessary functions to retime and align these signals from the backplane. VT1.5 tributaries are then preselected with a hardware 2:1 UPSR switch from the working VSC9187 BLOCK DIAGRAM: LEG_DI_S[5:0] LEG_RCLK_S LEG_RSYN_S TDM MUX [8] 9 x 622Mb/s STS-12 Serial Backplane Inputs (Service) MUX LASB Extraction [8:0] STS-1 A1/A2 Output Delay Mgmt (H1/H2) [8:0] 9 x 622Mb/s STS-12 Serial Backplane Inputs (Service) TDM DEMUX LEG_DO_S[5:0] LEG_TCLK_S LEG_TSYN_S and protection timeslot with programmable holdover and prehold switch timers. The results of the 2:1 hardware selection are then made available to an internal 3024x3024 VT1.5 nonblocking grooming switch, allowing a 5G UPSR ring to be terminated. Alternatively, the 9 protection STS-12 backplane inputs can remain unused and the VSC9188 can act as a 5G VT1.5 switch. Output STS-1 delay management following the crossconnect allows the VSC9187 to be used in subtended switch applications with large scale STS-1 crossconnects such as the VSC9182 40Gb/s STS-1 TSI.
