The APX HSSI Circuit Emulation Module (HCEM) is a member of the APX Universal Interface Module range. The HCEM provides the user with the capability to emulate a high speed circuit over an ATM backbone connection using unstructured AAL.1 adaptation. The HCEM operates transparently to payload data. The HCEM terminates a single ATM PVC and propagates clock information through the use of an adaptive clock mechanism. The HCEM provides a DCE interface for direct connection to a Router generating both the Transmit and Receive clocks. For connection to another DCE, for example a satellite modem, a cross-over cable is required.The Master Transmit clock is user configurable between 1Kbit/s and 110Mbit/s in 1 bit steps. To support Asymmetric operation the receive clock is also configurable between 1K and 110Mbit/s. The receive clock will adapt to within 100ppm of the nominal clock selection. Management and configuration of the HCEM is achieved via the simple menu driven user interface and may be monitored using SNMP Traps. | | 110 Mbps (max) | | HSSI, 50 way miniature AMP connector | | Unstructured | | Adaptive | | LOS, TXUR | | (Input) | | (Input) | | (Output) | | (Output) | | (Output) | | (Input) | | (Output) | | AAL.1 | | 80us | | ITU I.361.1 AAL.1
