In a redundant setup with a V.35 link to two Comtech modems, a special Y cable is needed. This cable links both units serial interface ports into a 1+1 (hot standby) setup. With this cable, both units actively listen to the incoming traffic. Internal management assures only one unit sends traffic onto the interface (the active unit). The redundant EIA-530/V.35 Y cable adaptor is available for all CX-U units. Serial Interface Speeds EIA-530 Signal Handling TX and RX LEDs The EIA-530 serial interface supports asynchronous or synchronous transmission at speeds up to 8,192 Mbps. The EIA-530 port can operate at 375 bps - 8,192 Mbps for external or internal clocking. Signaling through the EIA-530 port complies fully with the ITU-T s (CCITT) V.35 standard. Signaling, however, occurs through a generic DB-25 (RS-530) connector. These LEDs operate the same way as the V.35 LEDs in the front of the unit. As extracted from Table 2-2: 2-16 Memotec Inc.

34 CX-U Series Hardware Reference Manual 2.4 About the DLP and DDLP cards In addition to the hardware pre-installed on the motherboard of your unit, you can also add extra daugthercards which add processing power to your unit. Each DSP on these daughtercards can handle one or more T1/E1 ports, depending on which DSP application is active. For example, the EdgePlus DSP application can only handle one T1/E1 port, while the AbisXpress DSP application can handle two T1/E1 ports. NOTE: Other factors can influence the number of ports a DSP resource can support. To determine the number of DLP/DDLP cards you need for your network, please contact your Memotec representative. There are two types of daughtercards you can add to your CX-U unit: A DLP (Digital line processor) card has a single DSP resource that is used to compress traffic. The DDLP (Dual Digital line processor) has a dual DSP resources which doubles the processing power. Only the CX-U1000 series of units (revision 6 or later) supports the DDLP cards.
