- MC3GX60V - Line Cards is used for the Modular CMTS architecture.
- Capacity to Support 72 DS and 60 US channels, depending on the licence purchased.
- Support max. 15 Cable Mac Domains
- Each Mac Domain 32DS / 8 US
-20 US spigots for RF connectivity - organized into 5 groups of 4 connectors each
- Each connector group supports 12 frequency (4connectorx3USchannel-each 3 US channels per RF connector)
- flexibility to configure the US Connectors - 10 US spigots (each 6 US Channels per spigot)
- 6xGigabit Ethernet Interface Ports organized in three pairs
- Each Pair support 1+1 redundancy 24DS channels in Annex B mode by default.
-GE should be connected to the Edge Quadrature Amplitude Modulatuion (EQAM) device
and provide M-CMTS compliant Downstream External Phy interface ( DEPI) data.
The data is directed to only one GE Interface, through both the GE interfaces can be active at the same time.
-3G - because of the 3 Active GE ports - 24DS each port- ( 3 are passive)
x-times-60 Because of the upstreams
