<p><b>New page</b></p><div>A '''customer dial pulse receiver''', or '''CDPR''', is equipment in a telephone switch that receives digits dialed from a subscriber. Although the term refers to dial pulses, the same equipment may also be used to receive DTMF digits. In stored processor controlled switches, this is accomplished using a hardware DSP.<br />

== Crosstalk ==<br />
<br />
On 1ESS and 1AESS, CDPRs were frequently subject to crosstalk, such that subscribers could hear other people dialing digits during a call<ref>{{cite web |url=http://www.evan-doorbell.com/production/CentrexQ83p1.flac |title=The (1A ESS) Centrex Quirks of ‘83, part 1, 2:05-2:15 |last=Doorbell |first=Evan}}</ref>. This kind of crosstalk was more common on newer 1AESS systems than on the original 1ESS systems<ref>{{cite web |url=http://www.evan-doorbell.com/production/CentrexQ83p1.flac |title=The (1A ESS) Centrex Quirks of ‘83, part 1, 2:10-2:19 |last=Doorbell |first=Evan}}</ref>. <br />
