| CSU/DSU testing with a back to back shielded T-1 cable. Application for testing and line loading is TTCP (native to router IOS). Tests were done in two stages. Stage 1 had Rogeryoung act as the TTCP transmitter and the 2nd router Klendathu, acting as the TTCP receiver. Line utuilization and loading is maxed out for the duration of transfer (2GB of data). Results for stage 1: |
