Both SONET and SDH mappings are provided per Bellcore GR-253-CORE (VT1.5) and ITU-T G.707 3-96 (TU-11). A single add/drop Tele Bus is provided that can operate at either 6.48 or 19.44 MHz, which is patible with other TranSwitch devices. VT1.5/TU-11 pointer tracking and overhead extraction/processing with full error and alarm control is provided. VT1.5/TU-11 pointer calculation and overhead assembly is also provided. Alarm and error mappings from drop to add and SONET/SDH to/from DS1 are provided. Jitter performance is achieved with a...
