Description CT31V01 is a highly reliable 2Mbps G.703 / G.704 interface converter which provides interface conversion between E1/FE1 and V.35. The unit has a single G.703 port presented as two 75 Ohm BNC connecters as well as one 120 Ohm connectors presented as RJ-45. CT31V01 provides a simple method of gaining access to 2Mbps E1 (and fractional E1) leased lines. It fully meets all of the E1 specifications including G.703, G.704, G.706, G.732 and G.823. CT31V01 features diagnostic capabilities for performing local loopback and digital loopbacks. The operator at either end of the line may test both the CT31V01 and the line in the digital loopback mode. The loopback is controlled by either a manual switch or by the DTE interface for V.35. CT31V01 has a built in Bit Error Rate Tester (BERT), this can be operated via a front panel switch that activates an internal 511 bit pseudo random test pattern, according to ITU (CCITT), for direct end to end integrity testing. CT31V01 provides maximum flexibility in connecting both the G.703 / G.704 E1 interface and the user data interface. The E1 link may be clocked from the recovered receive clock, from the user data interface, or from an internal oscillator. - Single port access to E1 & Fractional E1. - Built-in LTU (Line Terminating Unit). - Protocol conversion between G.703 and V.35. - Transmission data rate from 64Kbps up to 2048Kbps.
