PBX Extension

PBX extension provides voice capabilities to teleworkers and remote callcenter employees, allowingthem to use digital phones to take advantage of their company’s voiceinfrastructure. Custom featuressuch as call redirect, voicemail, conferencing, speed dialing, and otherproductivity tools can be utilizedby workers not physically located at the corporate office.

At the teleworker’s location, there is a digital phone identical to theworker’s desktop PBX phone at thecorporate site. The digital phone connects to a remote PBX extender CPE thatconverts the voicesignal to IP packets for transport over DSL to the concentrator, whichreaches the corporate site overpublic or private data network. At the corporate site, a companion PBXextender unit attaches to thePBX station lines that are extended over the wide area network (WAN).

Using a local area network (LAN) extension from the enterprise, LAN traffic(data) may also be carriedover the DSL connection to the teleworker site. Since Copper Mountain’s DSLproducts can forwardIP packets securely at Layer 2, combining PBX extension and a corporate VPNfor data creates a secure,converged voice and data solution for remote workers. A remote worker can bemany miles from theSMB site, yet have direct access to the corporate PBX, email, and the companyintranet, just as if theywere sitting in the corporate office.

Baseband POTS

G.lite and Full-Rate Asymmetric DSL (ADSL) are DSL variants that carryhigh-speed data and a normalPOTS line on a single loop. POTS with ADSL is really voice under DSL; it is not packet voice at all.

G.lite is splitterless at the customer premise, and a standard POTS devicelike a phone or fax machinecan share the single copper loop that also transports data at speeds over 1.5Megabits per second(Mbps) downstream. At the CO, baseband POTS is separated from the data bymeans of a splitter, and can be groomed off to either the ILEC or CLEC circuit-switched analogfacilities.
