COMMSCOPE
E6000-DCCM

Downstream CCAP Core Module (DCCM)

The Downstream CCAP Core Module (DCCM) has the same MAC processing capacity of the 2nd generation Downstream Cable Access Module (DCAM-2). The DCCM and DCAM-2 can be used interchangeably to provide downstream MAC processing for the E6000 CCAP Core. Without RF hardware, the DCCM cannot be used for I-CCAP applications. E6000 Release 7.0 and later support “hybrid” operation of Integrated CCAP (I-CCAP) and CCAP Core within the same chassis.

The DCCM is essentially a DCAM-2 without the RF circuitry. The DCCM is meant only for R-PHY operation for which it provides the same functionality and capacity as the DCAM-2. The DCCM and DCAM-2 are interchangeable for R-PHY operation and can be mixed in the same E6000 chassis. The DCCM supports MAC processing for RPDs with downstream RF bands up to 1.2 GHz. In addition, the DCCM can support multiple 192 MHz OFDM channels per Service Group on capable RPDs. The DCCM offers power, weight, and cost savings over the DCAM-2 for Remote PHY applications. Use of DCCM requires the RSM-2 and either UCAM-2 or UCCM upstream modules.

Features:

• Downstream MAC processing for remote PHY operation on the E6000 CER acting as a CCAP core
• No RF input, R-PHY operation only
• Full spectrum capable (MAC processing for channels up to 1.2GHz)
• Interoperable with DCAM-2 in the same E6000 chassis
• Multiple DOCSIS 3.1 downstream channel support (24-192 MHz each) - dependent on software release and RPD capabilities
• DOCSIS 3.0 downstream (Annex A and Annex B) support - channel density dependent on software release and RPD capabilities
• Video SC-QAM support for VOD and broadcast services - channel density dependent on software release and RPD capabilities
• Channel deensity scalability via licensing or software upgrades (no hardware changes required)
• E6000 CCAP core interoperable for multi-core R-PHY architectures
• Deploys with CCAP Core Rear Card (CCRC) – one required on the back of the E6000 chassis for each DCCM
