Cheap Hardware Wanted
Any designs geared for business not only must comply with existing CableLabs DOCSIS 2.0 and PacketCable 1.0 VOIP specifications, but also must meet higher standards for business use. The ML-MTAs must survive the higher temperatures of utility closets, be wall-mountable or rackable, and provide alarms on malfunction, PSTN (Public Switched Telephone Network) failover and management tools.

Cox was the first to announce that it would put out an RFP for a multiline MTA. When others announced similar interest, the roundtable decided to make CableLabs the focal point for that process."In this way, we could get enough uniformity so that it would make economic sense for a vendor to produce the product and sell to a dozen members, rather than designing to sell to one member a dozen times," Bennington said. CableLabs also intends for the process to consolidate the market to a few vendors and get the price down low enough for the operators to bundle the equipment with service. CableLabs RFP contains a minimal set of requirements for the ML-MTA, whichin addition to DOCSIS and PacketCable VOIP conformanceinclude Ethernet connectivity, support for at least eight concurrent phone conversations, upstream data throughput with mixed frame sizes of 1.5 Mbps and downstream data throughput with mixed frame sizes of 5 Mbps, while all telephony connections are in use. Further requirements should come out of the proposals submitted by vendors. The full RFP can be viewed here in PDF form.
