Paradyne CPX-1000 manual STS-1 Ecac Module Controls, Indicators, and Ports

1000-A2-GN22-00 2. CPX-1000 Voice Services Platform Description

The STS-1 ECAC module increases the traffic capacity of the CPX over what can otherwise be obtained by T1 modules. When configured for redundancy (1 + 1), these modules occupy shelf slots 11-16 in pairs.

As with a T1-based configuration, the STS-1 configuration provides complete support for the GR-303 protocol including full GR-303 line concentration, CLASS and calling features, full EOC, TMC and path protection switching.

A single CPX shelf supports eight interface groups (IGs) with each port independently assigned to an interface group. Each interface group supports up to 28 DS1 ports. The CPX also supports path protection switching for the control channels in the GR-303 Interface group.

Table 2–7describes the controls, indicators and ports of the STS-1 module ports and indicators.
