Nokia Pop-Port
ThePop-Portinterface (originally codenamed "Tomahawk" )[citation needed]was aproprietaryplug-in port for accessories and data synchronisation, available with manyNokiamobile phones.The port consists of one metal pin on either end, and a plastic tab containing thirteen contacts. Pop-Port-like interfaces first appeared in Nokia phones since circa 1996, but the Pop-Port was standardised as a single interface in 2002.[1]
By early 2007 the Pop-Port was fully replaced by the industry standardUSB(miniUSB, and later by microUSB) sockets for data services and a 4-part 2.5mm or 3.5mm "standard"TRRS socketfor audio. Nokia had been equipping certain devices with one of these connectors as alternatives from about 2004.[citation needed]
Nokia filed "Pop-Port" as atrademarkin theUnited Stateson September 3, 2002.[2]
Functions
[edit]The port carries signals for hands-free microphone, stereo speakers,FBusRx/Tx orUSBsignals for the phones supporting them, power output for feeding the accessories that do not have their own batteries, and the Accessory Control Interface (ACI), a bidirectional serial control bus for connection and authentication of phone accessories, with a specificASICinside accessories and aproprietary protocol.It is also used to upgradeUSB-enabled phones' software using a specific USB data cable and theNokia Software Updater.Earlier cables connected toRS-232but later was replaced by USB.
Criticisms
[edit]A common problem with Pop-port was that contacts often lost connection, thus resulting in drop-outs in audio (when a hands-free device is used) or an unstable data connection (when a USB cable is used). This was a common problem when listening to music from the phone while the phone was in a pocket. The more stable 2.5 mm and 3.5 mm audio sockets aren't prone to such problems.
The contacts are exposed to dust and dirt, more so than those of aTRRS socket.This, combined with the small size of the contacts, prevented connections in some cases. Also, the plug's 'hook' tended to lose its hooking capability, making it even easier to accidentally lose connection. The data cables had to be original in most cases.
