DCC # Configurator
The DCC Control Rack (DCR) is a multi-channel programmable attenuator and RMS RF power monitor. This active DAS tray is a broadband multi-channel programmable attenuator and RMS RF power monitor. It performs as an active point of interface within the DAS system.
- Remote and local 8 channel (4 UL/4 DL) monitoring
- Remote and local power control
- Automatic Level Control (ALC)
- Works with legacy DAS equipment
- Cost effective implementation
The DCR can be used as a stand-alone base station interface to DAS if the input power levels are at a low value, but generally it is meant to work with High Power DCC Input Modules (HDI). It is 1RU high, 19" wide with self cooling. The non-modular design approach allows for cost effective compact application within the DAS. This is ideal for small venues, multiple small cells, and add-ons for large venues and existing passive DAS trays without the need for expensive modular equipment expenditures.
The DCR has broadband inputs, and it is controlled and configured by local Ethernet, remote Ethernet, or from a keypad on the front panel. It also supports SNMP V3 reporting. The DCR is designed for use in an indoor, temperature controlled environment. A preferable site for the DCR is a location free of obstructions, easily accessible and allows for proper air-flow and ventilation.
The DCR has a front panel LCD screen that displays power level and attenuation setting for each Tx/Rx channel. There are also the RF SMA(f) connectors, a keypad, local Ethernet, and status LEDs. AC input, a power switch, the main fuse, and remote Ethernet interface are in the back, along with two fans for self-cooling.
The DCR has a total of 4 pairs of uplink/downlink channels, from 698 MHz to 2700 MHz, with user programmable attenuation up to 62dB in 1dB steps. Narrowband power monitors detect and report uplink output power for each uplink path. Broadband power monitors detect and report input and output downlink power for each downlink path.
Ethernet interfaces are provided for remote and local control. Interface software allows configuration and monitoring via remote SNMP or local web server. In addition to setting attenuation levels individually for each of the 4 pairs of Tx and Rx channels, one can also monitor channel composite power levels, system temperature, alarm status and history, set alarm thresholds and SNMP traps.
The DCR can be fed by up to 4 HDI channels each with an uplink and downlink path. Individual duplex BTS ports are connected to the High Power Point Of Interface (HPOI). Individual channel frequencies need to be entered from front panel or web server so the DCR can identify the frequency calibration factors. High power front end modules are available in 700 MHz (lower and upper C blocks), SMR, 800 MHz Cellular, 1900 PCS, and AWS frequencies.
The DCR can be configured for many different DAS monitoring applications:
