The E7-2 VDSL2-48C line card can be plugged into one or both of the two universal slots
within a Calix E7-2 shelf to create a compact, very high density DSL node of 96 ports in a
1RU high chassis, for DSL and VOIP access. Pair bonding is supported in both ADSL2+
and VDSL2 modes.

The Calix E7-2 VDSL2-48D card can be plugged into one or both of the two universal slots
within a Calix E7-2 shelf to create a compact, high-density DSL node, with Ethernet
aggregation and transport, ideal for copper based delivery of IP services across the access
network. The line card supports pair bonding in both ADSL2+ and VDSL2 modes.
The Calix E7-2 VDSL2-48D Data-Only line card is ideally suited to meet new deployment
requirements for the “All-Digital loop” as well as traditional Class 5 TDM Voice Switch
consolidation applications. The All-Digital Loop provides high speed data services to all
subscribers with the VoIP POTS functionality provided as an integrated component of the
home residential gateway or as a separate IAD device attached to the modem. VoIP traffic is
packetized in the home and then forwarded across the Calix network to the SIP enabled
Softswitch. This application completely removes the POTS functionality from the service
loop as the VoIP traffic is forwarded as a prioritized data packet. Using the E7-2 VDSL2-
48D Data-Only line card Service Providers may continue to provide triple play services with
the voice element being classified as “digital voice” as compared to “Life-line POTS”.
In this application, the TDM Class 5 POTS and Splitters are external to the E7 solution. The
E7-2 VDSL2-48D Data-Only solution does not include splitter functionality. POTS services
in this application are provided by the Class 5 switch and the splitter function is external to
the E7 solution. In this application, high speed digital traffic is routed across the E7 while
POTS signaling is forwarded across the installed TDM network.
