Insight Communications has started to make vendor selections for the MSO's forthcoming rollout of IP telephony services.
Insight has placed orders for "multiple" ARRIS C4 cable modem termination systems (CMTSs) that house the vendor's high-density 2 downstream/12 upstream Cable Access Modules. The C4 is qualified for PacketCable 1.1, DOCSIS 2.0 and the Euro-DOCSIS 2.0 specification.
In making the selection, Insight CTO Charlie Dietz cited the C4's redundancy, hitless RF sparring and hitless software upgrade capabilities.
Insight presently supports its circuit-switched telephony service with ARRIS' Cornerstone platform.
